Answer:
82 degree 30'e has been chosen as the standard meridian of india because of the following reason:-
The longitudinal extent of India is 30 degrees. we all know that the sun rises in the east and sets in the west so it takes 4 minutes for the sun to move across a single longitude. The eastern most point of India is 2 hours ahead of the western most point, in accordance with local time. to avoid the confusion created by time differences a longitude passing through the mid point of 68 degrees and 7 minutes the west longitude and 97 degrees and 25 minutes east longitude is taken as the standard meridian of India
