Why do we need a Standard Meridian for India ?

Solution
The latitudinal and longitudinal extent of India is almost the same in degrees (i.e. 30 degree) but in kilometres, the north-south distance is 3200 kilometres while that of east-west distance i.e. 3000 km.
In order to bring uniformity in local time, the Standard Meridian of 82°30'E has been accepted. It passes through Mirzapur (U.P.). Hence, we can state that we need Standard Meridian for India to maintain a standard time.
