Explain why 82°30′ E an odd value has been chosen as the standard meridian of India. [HOTS]
The odd value has been chosen as the standard meridian because the longitudinal extent of India is 68°7′ E to 97°25′ E and this meridian passes through the centre of India. It passes through Mirzapur i.e. the centre of India. Then there is an understanding among the countries of the world that the degrees of the meridian should be divisible by 712 i,e. 82° 30′ E. This enables us to overcome the difference of 2 hours of time between Arunachal Pradesh and Gujarat. The time is Indian Standard Time.
