Why do we need a standard Meridian for India ?

Ans.

82!/2° East meridian is taken as the Standard Meridian of India. It passes through the town of Allahabad. Local time of Allahabad is taken as the standard time all over India. It is a central meridian for India as it divides the country into two equal halves. So it suits most parts of the country. Moreover, Nepal and Sri Lanka also adopt SlVf E as the Standard Meridian to have a uniformity of tern with India.
