1) In a Geography Book, Some Information About the States of India Is Present Which Is Given Below. Read the Information and Answer the Following Question:

States	Population (census 2011)	Area (sq. km)
Sikkim	610,577	7,096
Mizoram	1,097,206	21,081
Tripura	3,673,917	10,492
Nagaland	1,978,502	16,579
Goa	1,458,545	3,702

Which State Is Nearly 3 Times of Sikkim's Area? (Find the Estimated Value)
Which State Is Nearly Half of Sikkim's Area? (Find the Estimated Value)
Which State Is More Than 2 Times Tripura's Area?
Find the Difference in Population Between Goa and Sikkim.
Find the Total Area Covered by the Given Five States.

Area of Sikkim = 7096 sq. km
Now, three times of 7096
=

Now 21288 is near the number 21081.
21081 sq. km is the area of Mizoram.
Hence, the area of Mizoram is nearly three times of Sikkim.

b. Area of Sikkim = 7096 sq. km
Now, half of the number 7096

The number 3548 is near the number 3702
3702 sq. km is the area of Goa.
Hence, the area of Goa is half of Sikkim's area.

c. Area of Tripura = 10492 sq. km
Now, two times of 10492
=

Now 20996 is near the number 21081.
21081 sq. km is the area of Mizoram.
The area of Mizoram is more than two times Tripura's area.

d. The population of Goa = 1,458,545
Population of Sikkim = 610,577
Now, the difference
=

The population of Goa is more than the population of Sikkim.
The population difference between Goa and Sikkim is 847968.

e. The area covered by the given five states
=

Hence, the five states' total area is 58950 Sq. Km
