(g) Why is it 5.30 p.m in India when it is 12.00 noon in London?
In London, the Greenwich Mean Time (GMT) is followed. The Indian Standard Meridian is located 821/2∘ 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.
