Answer 1

Explanation:

1. The difference between two longitudinal extremes of India is 30°.

2. The difference between the two longitudinal extremes of mainland of India is less than the latitudinal distance of India. Here, you have not mentioned to what we have compare the longitudinal extremes of India. So I have taken latitudinal distance.

3. 82.5°E longitude in the city of Shankargarh Fort in Prayagraj district, Uttar Pradesh is called as Indian Standard Time (IST).

4. GMT is 0° and IST is 82.5°. So the angular difference is of 82.5°.

5. Indian Standard Time is 5 hours and 30 minutes ahead of Greenwich Mean Time.

Hope it helps.
