To find the time meridian of a country, take the westernmost longitude and the easternmost longitude of that country, take the mean, and find the nearest multiple of 7.5 degree.
As India's longitudinal extent is from 68° 7' 53" E to 97° 24' 47" E.
Nearest multiple of 7.5° is 82.5°.
So 82"30 minutes east has been selected as the standard meridian time of India
