How many zeros are there in one crore?

A. 5

B. 6

C. 7

D. 8

Since we are unsure about the number of zeros in a crore, let’s understand it step by step using smaller units:

• Ten hundreds make one thousand (1,000).
• One hundred thousand makes one lakh (1,00,000).
• Ten lakhs make one million (10,00,000).
• Ten million make one crore (1,00,00,000).

From this, we can clearly see that one crore has seven zeros.

Therefore, the correct answer is Option C (7 zeros).
