Explanation:
Detailed explanation-1: -There is a general understanding among the countries of the world to select the standard meridian in multiples of 7°30’ of longitude. That is why 82°30’ E has been selected as the ‘standard meridian’ of India.
Detailed explanation-2: -Because 15 degrees of longitude is equivalent to 1 hour in time (that is 360 / 24) it is convenient to adopt time zones at 7.5 degrees or 15 degrees multiples. In other words time zones are separated by multiples of 1 hour or 1/2 hour.
Detailed explanation-3: -The standard meridian of India is 82°30’E. It passes through Mirzapur (Uttar Pradesh). The time of this meridian is taken as the standard time for the whole country.
