Question

Longitudinal and Latitudinal Extent of India is _______.
a. 8°3 N-38°5 N latitudes and 65°5 E-97°21 E longitudes
b. 7°9 N-37°5 N latitudes and 65°5 E-97°21 E longitudes
c. 8°4 N-37°6 N latitudes and 68°7 E-97°25 E longitudes
d. 8°4 N-37°6 N latitudes and 68°7 E-97°24 E longitudes

Answer 1

Hint: The longitudinal extent of India is less than 30 degrees whereas the latitudinal extent is also less than 30 degrees. Also, India lies partially in the tropical zone and partially in the sub-tropical zone.

Complete answer:
The extent of India's latitudes and longitudes can be found using memory.
Let’s look at our options one by one:
a. 8°3 N-38°5 N latitudes and 65°5 E-97°21 E longitudes - The latitudinal extent is too large, and we know that it is less than 30 degrees. Also the longitudinal extent is larger than 30 degrees. So, it is an incorrect option.
b. 7°9 N-37°5 N latitudes and 65°5 E-97°21 E longitudes - The latitudinal extent is not too large, and we know that it is less than 30 degrees. But, the longitudinal extent is larger than 30 degrees. So, it is an incorrect option.
c. 8°4 N-37°6 N latitudes and 68°7 E-97°25 E longitudes - The latitudinal extent is well within range of approximation, as we know that it is less than 30 degrees. Also the longitudinal extent is less than 30 degrees. So, it is the correct option
d. 8°4 N-37°6 N latitudes and 68°7 E-97°24 E longitudes - The latitudinal extent is not too large, as we know that it is less than 30 degrees. So, it is an incorrect option.

Note: The latitude of 10 degrees N is an important latitude as it separates the Andaman and the Nicobar islands. The actual extent of India is till the 6 degrees N latitude due to the Indian administration over Andaman and Nicobar Islands. The above question discusses only the mainland of India.
