Key Concept: Salary as an Economic Activity

b) Because he gets paid for his work
[Solution Description]
Rohan receives a fixed monthly salary for his work as a software engineer. This exchange of services for money makes it an economic activity.

Key Concept: Uniform significance, Career choices

b) It indicates they work in different areas or services.
[Solution Description]

In many workplaces—especially government jobs, security, healthcare, and sanitation—uniform color signifies the department or role of a worker. For example, a nurse, police officer, railway worker, or sanitation worker might each have distinct colors or styles of uniform.

So, the difference in Geeta Aunty’s and Kabir’s grandfather’s uniforms helps others identify their respective job roles or departments, showing dignity of labor and how every role is important.

Swachh Bharat Abhiyan is a community-driven initiative where people participate voluntarily to keep public spaces clean without expecting monetary compensation. This aligns with non-economic activities as the motivation comes from a sense of responsibility and societal contribution rather than financial gain.

Key Concept: Sevā, Non-economic activities

c) Selfless service and communal harmony
[Solution Description]
Langar in gurudwaras represents sevā (selfless service), which is a non-economic activity. The primary principle here is serving others without expecting anything in return, fostering gratitude and community bonding, which does not involve monetary transactions.

Key Concept: Economic vs Non-Economic Activities, Sevā

b) Serving food is non-economic, while designing is economic.
[Solution Description]
The first activity (serving food at the gurudwara) is a non-economic activity because it is done out of selfless service (sevā) without monetary gain. The second activity (freelance graphic designing) is an economic activity because it involves earning a fee for services provided. Thus, the correct statement must distinguish both types of activities accurately.

Key Concept: Economic vs Non-economic Activities

Key Concept: Sevā and Non-Economic Activities

c) Serving free meals at a gurudwara
[Solution Description]
Sevā refers to selfless service, often seen in places like temples or gurudwaras, where services like langars (community kitchens) are provided for free. The correct option should match this concept of unpaid, altruistic service.

Key Concept: Value Addition, Economic Activities

d) Rs.3,000
[Solution Description]
First, calculate the total revenue generated by the bulldozer:
Total Revenue = Bulldozer Rental per Day × Number of Working Days
Total Revenue = Rs.5,000 × 20 = Rs.100,000
Next, subtract the Salary Paid to Technician from the Total Revenue to find the Value Added:
Value Added = Total Revenue - Salary Paid
Value Added = Rs.100,000 - Rs.40,000 = Rs.60,000
Now, divide the Value Added by the Number of Working Days to get Daily Value Added:
Daily Value Added = Rs.60,000 ÷ 20 = Rs.3,000
The daily value added by Kavya's uncle is Rs.3,000.

Key Concept: Economic Activities, Indirect Benefits

d) Rs.1,500
[Solution Description]
First, calculate the Fuel Cost Saved:
Time Saved = Old Travel Time - New Travel Time
Time Saved = 5 hours - 2 hours = 3 hours
Fuel Cost Saved = Time Saved × Fuel Cost per Hour
Fuel Cost Saved = 3 hours × Rs.200 = Rs.600
Next, calculate the Earnings from Time Saved:
Earnings = Time Saved × Earning Rate per Hour
Earnings = 3 hours × Rs.300 = Rs.900
Now, calculate the Total Indirect Economic Benefit:
Total Benefit = Fuel Cost Saved + Earnings from Time Saved
Total Benefit = Rs.600 + Rs.900 = Rs.1,500
The total indirect economic benefit per trip is Rs.1,500.

Key Concept: Types of Economic Activities

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that operating a bulldozer and getting paid for it is an economic activity. This is true because the syllabus defines economic activities as those involving payment, such as earning a salary. The reason explains that all money-earning activities through goods or services are economic activities, which correctly supports the assertion. Therefore, both statements are true, and the reason properly explains the assertion.

Key Concept: Economic Activities, Value Addition

d) \$300
[Solution Description]
Value addition is calculated as the difference between the selling price and the cost of inputs at each stage. For the farmer, value added = \$100 (since there are no prior costs). For the miller, value added = \$180 - \$100 = \$80. For the baker, value added = \$300 - \$180 = \$120. Total value added = \$100 + \$80 + \$120 = \$300.

[Solution Description]
A market is a place where people exchange goods and services, usually for money.

Key Concept: Economic Activities, Money's Worth

d) \$1000
[Solution Description]
Value added is calculated as the difference between the selling price and the cost price at each stage. For the farmer, value added is \$500 (since there is no cost mentioned). For the wholesaler, value added is \$700 - \$500 = \$200. For the retailer, value added is \$1000 - \$700 = \$300. Total value added is \$500 + \$200 + \$300 = \$1000.

Key Concept: Value of Non-Economic Activities

c) They enhance community bonding and environmental health
[Solution Description]
The syllabus states that non-economic activities foster social welfare, personal wellbeing, and quality of life. Tree plantation drives improve the environment (social welfare) and give participants a sense of satisfaction (personal wellbeing).
Option A incorrectly ties them to income. Option B focuses on profit, which contradicts the syllabus. Option C correctly highlights their social and personal benefits. Option D misrepresents them as income-generating. The answer is C.

Key Concept: Non-Economic vs Economic Activities, Compensation, Motivation

c) The absence of monetary motivation in the grandfather’s case
[Solution Description]

Option c) is correct because organizing a free medical camp fits the definition of selfless service without any economic motive.

Key Concept: Non-Economic Activities

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The syllabus defines non-economic activities as those done out of feelings like gratitude, love, care, and respect, not for income or wealth. Cooking for the family fits this definition as it is an act of care without financial motivation. Therefore, both Assertion and Reason are true, and the Reason correctly explains why cooking for the family is a non-economic activity.

Key Concept: Non-Economic Activities

c) Volunteering at a local shelter to feed the homeless
[Solution Description]
Non-economic activities are those performed out of love, care, or respect without expecting any monetary benefit. Among the options listed, only one fits this criterion. Cooking for family members is done out of care and does not involve financial transactions.

Key Concept: Volunteering, Sevā

d) One operates purely on generosity while the other maintains financial considerations
[Solution Description]
Langar is selfless service (sevā) where food is given unconditionally as spiritual practice, regardless of recipients' ability to pay. The restaurant's initiative, while charitable, still operates within commercial framework with suggested donations. Non-economic sevā expects nothing in return, while commercial establishments ultimately aim for sustainability.

Key Concept: Economic and Non-Economic Activities

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that a business person selling school bags in the market is engaged in an economic activity, which is true as per the syllabus ("Economic Activities: Those that involve money or are performed in exchange for money or money’s worth"). The reason explains why it is an economic activity by stating that such activities involve money or money’s worth, which directly aligns with the definition provided in the syllabus. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.

Key Concept: Value Addition

c) Enhancement through transformation stages
[Solution Description]
Value addition in economic activities refers to the enhancement of value at each stage of transforming raw materials or inputs into finished goods or services. As per syllabus, this process occurs through various production stages where economic value is progressively added, distinguishing it from non-economic activities or simple exchange scenarios.

Key Concept: Economic vs. Non-Economic Activities

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that selfless service (Sevā) like serving food in langars at gurudwaras is a non-economic activity, which is true because it does not involve monetary transactions. The reason explains that non-economic activities do not involve money but create social and emotional value, which is also true and correctly explains the assertion.

Key Concept: Significance of Uniform

c) It represents her commitment to serving the nation
[Solution Description]
The uniform represents her profession and her dedication to serving the nation. It distinguishes her as a member of the Indian Air Force, highlighting her dual role in economic activity and national service.

Key Concept: Opportunity Cost, National Service

b) \$20,000
[Solution Description]
Opportunity cost is the difference between what she earns now and what she could have earned elsewhere, adjusted for non-monetary benefits. Corporate Salary (\$80,000) - Air Force Salary (\$40,000) = \$40,000. Subtract the non-monetary benefits (\$20,000): \$40,000 - \$20,000 = \$20,000. Thus, the net opportunity cost is \$20,000 per year.

Key Concept: Economic Activity vs. National Service

c) She combines economic activity with national service
[Solution Description]
Geeta Aunty serves as an Air Force pilot, which is both an economic activity (as she receives a salary) and a service to the nation (as she protects national security). The uniform signifies her professional commitment to serving the country.

Key Concept: Economic vs Non-economic Activities

d) Assertion is false, but Reason is true.
[Solution Description]
The assertion claims that Rohan’s teaching at the youth development programme is economic because it enhances his professional reputation. However, non-economic activities are those performed out of goodwill or community service without monetary compensation, regardless of indirect benefits like skill enhancement. Thus, the assertion is false. The reason states that any activity contributing to employability should be economic. While some activities may enhance employability, they remain non-economic if done without payment or profit motive. Hence, the reason is also false. Therefore, both the assertion and reason are incorrect in this context.

Key Concept: Non-Economic Activities

c) Parents cooking food for their family
[Solution Description]
A non-economic activity is something done out of feelings like love, care, or respect without generating any income. Parents cooking food for their family is an example of a non-economic activity, whereas working in an office or running a shop earns money and are economic activities.

Key Concept: Economic and Non-Economic Activities

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that Rohan's volunteering is a non-economic activity. According to the syllabus, non-economic activities do not generate income or wealth but are undertaken due to feelings such as gratitude, love, care, or respect. The reason explains why volunteering qualifies as a non-economic activity—because it lacks monetary compensation and stems from altruistic motives. Both the assertion and reason are true, and the reason correctly explains the assertion.

Key Concept: Value Addition

c) Value addition through labor and expertise
[Solution Description]
The difference between the selling price (Rs.1,000) and the cost of raw materials (Rs.600) is Rs.400. As explained in the syllabus, this amount represents the monetary value added by Rajesh’s skill, time, and effort in transforming wood into furniture—an example of value addition in economic activities.

Key Concept: Transportation, Economic Impact

c) Rs.300
[Solution Description]
Current fuel cost for 5-hour trip = Rs.500. Fuel cost is proportional to time, so cost for 2-hour trip = (Rs.500 ÷ 5) × 2 = Rs.200. Savings per round trip = Rs.500 - Rs.200 = Rs.300.

Key Concept: Economic Activities and Payment Methods

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that Sahil's receipt of mangoes as part of his payment is an example of wage labor. This is true because wage labor includes all forms of compensation for work, including non-cash payments like mangoes. The reason states that payment in kind refers to non-cash compensation, which is also true. Moreover, the reason correctly explains why Sahil's income in the form of mangoes qualifies as payment in kind, directly supporting the assertion.
Therefore, both the assertion and reason are true, and the reason is the correct explanation of the assertion.

Key Concept: Wage Calculation, Economic Impact

c) $17,280
[Solution Description]
Calculate monthly expenditure: \$1,200 × 80% = \$960
Total expenditure over 18 months: \$960 × 18 = \$17,280

Key Concept: Economic Activities, Value Chain

Total wage expenditure: \$12,500 + \$12,500 + \$7,500 = \$32,500

Key Concept: Economic Activities and Payment Methods

d) Payment in kind
[Solution Description]
The question describes Sahil receiving partial payment in mangoes, which is termed as "payment in kind" according to the syllabus.

Key Concept: Salary Comparison, Additional Work, Tax Deduction

b) 9.44%
[Solution Description]
The first worker earns \$1,500 monthly. The second worker earns 20% more, so:
20% of \$1,500 = 0.2 * \$1,500 = \$300.
Second worker's salary = \$1,500 + \$300 = \$1,800.
Both workers pay \$170 in tax. For the second worker, the tax percentage is:
(\$170 / \$1,800) * 100 = (170/1800)*100 ≈ 9.44%.

Key Concept: Employment and Additional Work

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The Assertion states that Kavya's income increases due to her dual roles—working at the post office and conducting online classes. This is true as she receives a fixed salary and an additional weekly fee. The Reason explains that engaging in multiple sources of work improves financial stability, which is also correct. However, the Reason does not directly explain why Kavya's income increases; it provides a broader benefit of such behavior. Therefore, both statements are true, but the Reason is not an exact explanation of the Assertion.

Key Concept: Salary, Weekly Earnings, Total Income

b) \$1,530
[Solution Description]
First, calculate the monthly earnings from online classes:
Number of weeks = 4, fee per week = \$50.
So, class income for the month = 4 * \$50 = \$200.
Next, add the fixed salary to the class income:
Total gross income = \$1,500 + \$200 = \$1,700.
Now, subtract 10% tax from the total income:
10% of \$1,700 = 0.1 * \$1,700 = \$170.
Net income = Gross income - tax = \$1,700 - \$170 = \$1,530.

Key Concept: Total wage calculation, Mixed payment

c) \$150
[Solution Description]
Daily cash wage is \$25, and mangoes are worth half of this, so mangoes per day: $25 / 2 = \$12.50$. Total cash in 4 days: $25 \times 4 = \$100$. Total mangoes in 4 days: $12.50 \times 4 = \$50$. Total earnings = $100 + 50 = \$150$.

Key Concept: Payment in kind, Wage calculation

c) \$300
[Solution Description]
Sahil earns \$40 per day in cash and \$20 worth of mangoes per day. Total cash earned in 5 days: $40 \times 5 = \$200$. Total value of mangoes received in 5 days: $20 \times 5 = \$100$. Total earnings = Cash + Mangoes = $200 + 100 = \$300$.

Key Concept: Farm Laborer Wages

c) Payment in kind
[Solution Description]
When a laborer receives part of their wage in goods (like mangoes), it is termed as payment in kind.

Key Concept: Value Addition, Opportunity Cost, Economic Decision

b) \$250
[Solution Description]
Opportunity cost is the income Rajesh could have earned if he had chosen the next best alternative (consulting). At \$50 per hour for 5 hours, the opportunity cost is \$50 * 5 = \$250. No other costs are considered here as per the question.

Key Concept: Value Addition, Cost Calculation, Economic Activities

b) \$300
[Solution Description]
Total cost of inputs = Cost of wood (\$600) + Cost of tools and materials (\$100) = \$700. Selling price of the chair = \$1,000. Value added = Selling price - Total cost of inputs = \$1,000 - \$700 = \$300.

Key Concept: Concept of Value Addition

c) Monetary value of Rajesh's skill, time, and effort
[Solution Description]
The remaining Rs.400 represents the monetary value of Rajesh's skill, time, and effort used to turn the wood into a chair. This is the value added by Rajesh.

Key Concept: Value Addition

b) Rs.400
[Solution Description]
Value addition is calculated as the difference between the selling price and the cost of raw materials. Here, selling price = Rs.1,000 and cost of wood = Rs.600. Therefore, value addition = Rs.1,000 - Rs.600 = Rs.400.

Key Concept: Economic Activities, Profit Calculation

c) 50%
[Solution Description]
Total cost = Rs.800 (fabric) + Rs.200 (threads/buttons) = Rs.1,000. Selling price = Rs.1,500. Profit = Rs.1,500 - Rs.1,000 = Rs.500. Profit percentage = ($\frac{Rs.500}{Rs.1,000} \times 100 = 50%$).

Key Concept: Profit Calculation

c) Rs.1,500
[Solution Description]
Total revenue from selling 5 chairs: $5 \times Rs.1,000 = Rs.5,000$. Total cost is given as Rs.3,500. Profit is calculated as $Rs.5,000 - Rs.3,500 = Rs.1,500$.

Key Concept: Compensation for Economic Activities

c) Compensation for skill and effort
[Solution Description]
The remaining Rs.400 ($Rs.900 - Rs.500$) compensates the tailor for his skill, effort, and time spent in stitching the dress. This is how value addition works in economic activities.

Key Concept: Economic Activities

c) Value added through skill and effort
[Solution Description]
The difference between selling price (Rs.400) and cost of raw material (Rs.150) is Rs.250. This represents the value added by the potter’s skill, effort, and time in transforming clay into pottery.

Key Concept: Value Addition

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
Rajesh buys wood for Rs.600 and sells the chair for Rs.1000. The difference of Rs.400 ($Rs.1000 - Rs.600$) represents the value added by Rajesh's skill, effort, and time. Therefore, both Assertion (A) and Reason (R) are true. Additionally, Reason (R) correctly explains why Rajesh earns Rs.400 as profit, making it the correct explanation for Assertion (A).

Key Concept: Community Participation, Examples of Non-Economic Activities

c) It builds trust and cooperation among neighbors
[Solution Description]
Neighbors helping each other in house renovations without monetary exchange is a non-economic activity that builds trust and cooperation within the community. It reduces reliance on paid labor, promotes mutual aid, and enhances the overall quality of life through strengthened interpersonal relationships. This exemplifies how non-economic activities can create long-term social capital rather than immediate financial gain.

Key Concept: Value of Non-Economic Activities, Festivals

c) It enhances personal well-being and fosters social bonding
[Solution Description]
The Diwali decoration event is a non-economic activity as it involves no monetary exchange but holds significant social value. Such events enhance personal well-being through creativity and teamwork, foster social bonding, and preserve cultural traditions. These aspects collectively improve the quality of life beyond mere financial considerations, fulfilling emotional and communal needs.

Key Concept: Non-Economic Activities

c) Parents teaching their child to ride a bicycle
[Solution Description]
Non-economic activities are those performed out of love, care, or gratitude without any monetary gain. Cooking food for family, helping children with homework, or volunteering at a community kitchen (like langar in gurudwaras) are examples of non-economic activities. These do not involve payment but hold social and emotional value.

Key Concept: Sevā: selfless service

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that sevā fosters a sense of satisfaction and gratitude, which is true as mentioned in the syllabus (e.g., langars at gurudwaras}. The reason given is that sevā involves contributing to society without expecting anything in return, which is also correct and directly explains why it fosters satisfaction and gratitude (selflessness leads to inner fulfillment). Hence, both are true, and the reason correctly explains the assertion.

Key Concept: Non-Economic Activities, Societal Impact

b) Promoting social equality through shared dining.
[Solution Description]
While langar feeds people, its deeper impact lies in fostering equality and community bonding by serving everyone irrespective of background. This aligns with the syllabus's emphasis on non-economic activities generating social value. Option B highlights this broader significance.

Key Concept: Sevā, Langar, Prasād

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that practices like distributing prasād and langar foster social equality by providing the same food to everyone, irrespective of economic status. This is true as these practices ensure no discrimination based on wealth. The reason states that sevā (langar and prasād distribution) is a non-economic activity promoting inclusivity and unity. This is also true because sevā does not involve monetary transactions and aims to bring people together. Moreover, the Reason explains why the Assertion holds—because sevā is designed to eliminate inequalities through selfless service, it naturally fosters social equality. Thus, both are true, and the Reason correctly explains the Assertion.

Key Concept: Langar and Seva

d) To offer free meals and promote equality through selfless service
[Solution Description]
Langar is a community kitchen where free meals are served to all visitors regardless of their background. It represents the Sikh principle of equality and selfless service (seva). The primary purpose of langar is to foster a sense of community, gratitude, and equality among people.

Key Concept: Community Participation, Sevā

d) Langar serving free meals at a gurudwara
[Solution Description]
The activity must align with the principles of selfless service (sevā) and contribute to both personal fulfillment and social unity.
- Langar at Golden Temple is a form of sevā as it serves food without any expectation of return, promoting gratitude and community bonding.
- Parents cooking dinner for their family is non-economic but not necessarily sevā as it involves familial responsibility rather than community service.
- Van Mahotsav promotes environmental awareness but is more focused on conservation, not directly sevā.
- Swachh Bharat Abhiyan involves collective cleanliness efforts, aligning with sevā and social cohesion.
Thus, both langar and Swachh Bharat Abhiyan fit. However, langar specifically embodies sevā more explicitly.

Key Concept: Sevā - Selfless Service

c) At gurudwaras during langar
[Solution Description]
Sevā is practiced in religious and community spaces where services like free food distribution (e.g., langars in gurudwaras) are offered without expectation of return.

Key Concept: Economic Life, Non-Economic Value

c) They reinforce social unity and cultural identity.
[Solution Description]
Non-economic activities during festivals strengthen social bonds, foster cultural continuity, and enhance communal well-being. Though unpaid, they build trust and cooperation, which indirectly supports economic resilience (e.g., shared resources during crises). Their value lies in intangible benefits like happiness and social cohesion.

Key Concept: Community Participation

d) Assertion is false, but Reason is true.
[Solution Description]
The assertion claims that the Swachh Bharat Abhiyan is successful due to individual efforts alone, which is false because the syllabus highlights that collective efforts of all Indian citizens are crucial for its success. The reason states that collective community participation is essential for such initiatives, which is true as per the syllabus. Therefore, the assertion is false, but the reason is true.

Key Concept: Long-term Sustainability, Multi-stakeholder Engagement

[Solution Description]
Business contribution is 40% of $500,000, which is $500000 \times 0.40 = 200000\$ dollars. This model ensures sustainability by involving multiple stakeholders (businesses and government), reducing financial burden on any single entity, and fostering community ownership.

Key Concept: Conceptual Understanding

c) Collective efforts of all citizens
[Solution Description]
The initiative thrives on the idea that every citizen's participation is crucial to achieving nationwide cleanliness, highlighting the power of shared responsibility.

Key Concept: Collective Action, Resource Management

c) 120,000 liters/month
[Solution Description]
Number of participants = 40% of 2000 = 800 residents. Total trees planted = 800 * 3 = 2400 trees. Water required per tree = 50 liters/month. Total water needed = 2400 trees * 50 liters/tree = 120,000 liters/month.

Key Concept: Community Participation, Economic Impact

b) \$200,000
[Solution Description]
First, calculate the current total economic value: 500 trees * $2000 = \$1,000,000. With a 20% increase in participation, the number of trees planted would also increase by 20%. New number of trees = 500 + (20% of 500) = 500 + 100 = 600 trees. Additional trees planted = 100. Additional economic value = 100 trees * \$2000 = \$200,000.

Key Concept: Community Participation

c) To achieve cleanliness through collective efforts
[Solution Description]
The Swachh Bharat Abhiyan aims to achieve cleanliness across India through collective efforts. It encourages citizens to maintain cleanliness in their homes, neighborhoods, and public places. This initiative promotes community participation to ensure a clean and hygienic environment nationwide.

Key Concept: Community Participation, Swachh Bharat Abhiyan

c) Transient population leading to reduced community engagement
[Solution Description]
The Swachh Bharat Abhiyan aims for collective participation, but urban areas often face issues like lack of awareness or reluctance among residents to participate actively. One major challenge is the transient nature of urban populations, where people may not feel a strong sense of belonging or responsibility toward public spaces.
