Question

Give two reasons for choosing 82 1/2 degrees E longitude as the standard meridian of India?

Answer 1

India is vast country so, we must have a standard time to be followed everywhere for safe and successful trade and transactions. This leads to the choosing of a standard meridian which is 82 1/2°.
To avoid inconveniences, between East and West, we need to choose a meridian passing through the centre part of the country.
Any standard meridian all over the world should be divisible by 7 and 82 1/2° is divisible.
Thanks.
