Question

Why is the 5:30 PM in India and 12:00 noon in London?​

Answer 1

Answer:

The Indian Standard Meridian is located 82½° east of the Prime Meridian. Thus the Indian Standard Time (IST) is 5 hours and 30 minutes ahead of GMT. ... That is why, when it is 12 noon in London, it is 5.30 P.M. in India. As we know the earth rotates form west to east the sun rays first fall on the eastern most longitudes.

Answer 2

It is because The “Greenwich Mean Time” (GMT) is being followed in London. The Indian Standard Meridian is situated 'east of the Prime Meridian' at 82 1⁄2°.
