Answer 1

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 is12 noon in London, it is 5.30 P.M. in India. ... So, when it is 12 noon in London, it is 5.30 P.M. in India.

• India and the United Kingdom lie on different longitudes. Each degree of longitudes corresponds to a difference of four minutes. This is because the earth rotates 360° in 24 hours, 1° in 4 minutes. The standard meridian of India is 82° 30′ E, and that of London is 0°. This means a difference of 4 minutes x 82.5 = 330 minutes = 5.5 hours. So when it is 12 noon in London, it is 5.30 p.m. in India.
