Key Concept: Food waste, Farmer's effort

c) 6 chapatis, significant wastage
[Solution Description]
First, calculate 20\% of 30 chapatis:
20\% of 30 = (20/100) * 30 = 6 chapatis.
This means out of 30 chapatis bought, 6 are wasted, representing the wasted effort of farmers and others involved in getting food from farm to plate.

Key Concept: Food Miles

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that reducing food miles helps cut down the cost and pollution during transport. This is true because shorter distances mean less fuel consumption and lower emissions. The reason explains that the longer the distance food travels, the more fuel is consumed, leading to higher costs and pollution. This directly supports and explains the assertion. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.

Key Concept: Food miles, Pollution, Local farmers

a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
[Solution Description]
The assertion states that reducing food miles decreases the carbon footprint of food transportation, which is true because shorter distances mean fewer emissions from vehicles. The reason explains that locally grown food needs less fuel for transport, leading to lower greenhouse gas emissions, which is also true and correctly explains why reducing food miles cuts carbon footprint. Thus, both assertion and reason are true, and the reason is the correct explanation of the assertion.

Key Concept: Food Miles Concept

b) It reduces transportation pollution and costs
[Solution Description]
Reducing food miles helps cut down transportation costs and pollution, supports local farmers, and keeps food fresher and healthier.

Key Concept: Process of Food Production

b) Transport to retail shop
[Solution Description]
According to Fig. 3.10, after grinding and packing the grains, the next step is transporting the packed flour to retail shops where consumers can purchase it. This ensures the product reaches the market efficiently.

Key Concept: Food Miles Concept

d) Food miles
[Solution Description]
The term used for the total distance traveled by food from the producer to the consumer is called "food miles". This concept emphasizes the importance of reducing distance to cut costs and pollution.

Key Concept: Food miles, Process of chapati making

c) Transport from retailer to consumer as it covers maximum states
[Solution Description]
The food miles concept refers to the total distance traveled by food from producer to consumer. In this case:
1) Punjab to Delhi is first transport (farm to mill)
2) Delhi to Mumbai is second transport (mill to retailer)
3) Mumbai to Chennai is final transport (retailer to consumer)
The longest distance that affects both cost and pollution would be either Delhi-Mumbai or Mumbai-Chennai, as these involve cross-country transportation rather than local movement. Since Mumbai-Chennai covers a greater geographical distance across states compared to Delhi-Mumbai, this leg adds the most to food miles.

Key Concept: Definition of Food Miles

b) The distance traveled by food from farm to plate
[Solution Description]
According to the syllabus, food miles is defined as the entire distance traveled by a food item, such as wheat, from the producer (farmer) to the consumer (our plate). It includes all steps like transportation, processing, and storage.
