Hint: We can simply write the amount in figures. We can put zeros by counting from the unit place, tens place, hundredth place, thousandth place, ten-thousandth place, lakh place, ten lakh place, crore place, and in the 10 crores’ place, we must write 1. Then we can count the number of zeros that come after 1.

Complete step by step Answer:

We are asked to find the number of zeros in 10 crores. We can put zeros by counting from the unit place, tens place, hundredth place, thousandth place, ten-thousandth place, lakh place, ten lakh place, crore place and we must write 1 in the 10 crores’ place. We can write 10 crores in figures as follows,
${\text{10,00,00,000}}$
From the above digits, we can easily count the number of zeros after 1. By counting, we will get the number of zeros to be 8.
So, there are 8 zeros that come after 1 in 10 crores.
Therefore, the correct answer is option C.

Note: We must use commas to separate the digits while writing large figures. This helps us for writing the digits and also to count the digits. Another method for doing this problem is to convert 10 crores into exponential form to the base 10 and the power of 10 will be the number of zeros. We can also count the number of zeros that must be added to 1 to get 10 crores. The answer will be the same method we do.
