Question: 100 million is equal to

(a) 1 crore (b) 10 lakh (c) 10 crore (d) 100 crore

Million refers to a number in the International Number System, whereas, lakh and crore is used in the Indian Number System.

Answer: 100 million is equal to 10 crores.

Let us understand the relationship between million, lakh and crore.

Explanation:

According to Indian number system,

1 lakh = 1,00,000

10 lakh = 10,00,000

1 crore = 1,00,00,000

10 crore = 10,00,00,000

According to International number system,

1 million = 1,000,000

Ten million = 10,000,000

Hundred million = 100,000,000

Therefore, it can be said that:

10 Lakh = 1 Million (since both are written as 1 followed by 6 zeros)

1 crore = 10 Million (since both are written as 1 followed by 7 zeros)

10 crore = 100 Million (since both are written as 1 followed by 8 zeros)

Thus, Option (c) is the correct answer. 10 crore is equal to 100 million.
