Solution
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.
