Question

The easternmost longitude of India is
A. 97°25'E
B. 68°7'E
C. 77°6’E
D. 82°30'E

Answer 1

Hint: In order to trace points in the earth surface longitudes and latitudes are used by cartographers and geographers on the globe. The equator is an imaginary line which is equidistant from North to South poles which divides the globe into northern hemisphere and southern hemisphere.

Complete Answer:
The lines are imaginary circles parallel to the equator. Latitudes help to find the north-south position of a location on the globe.
Longitudes are the imaginary circles that intersect the north and south poles and the equator. These run from the North pole to the South pole intersecting the equator. To specify the east and west position of a location longitudes are used.
In the Northern hemisphere, India is located. The division of India takes place due to the Tropic of Cancer which passes at 23°30’N. The latitude of 8°4’N and 37°6'N signifies the south to North position of India and the longitudes 68°7’E and 97°25’E which signifies the western and eastern position of the earth. At the latitude of 37°6’N is the extreme north position of India and the easternmost longitude of India is 97°25'E. The easternmost point is 2 hours ahead as compared to the western point. The easternmost point is located at Arunachal Pradesh in the northeastern region of India. A local time of central meridian is adopted in India as standard time since the difference between Dwarka in Gujarat and Dibrugarh in Assam is of 1 hour and 45 minutes therefore Indian Standard Time is adopted for India.
So, the correct answer is Option A.

Note: The easternmost longitude of India is 97°25’E which is located in Arunachal Pradesh which is the northeastern state of India. Since there is 29° of longitudinal extent there could be a difference in local time in India therefore Indian Standard Time is adopted for all the regions in India.
