Correct Answer - Option 3 : 24

**Given :**

The number of zeros at the end of the number obtained, by multiplying the number from 1 to 100 will be:

**Calculation :**

For every 5 in unit place one zero is added so between 1 to 100 there are 10 nos like 5, 15, 25, ...., 95 which has 5 in unit place.

Similiarly for every no divisible by 10 one zero is added in the answer so between 1 to 100 11 zeros are added for 25, 50, 75 3 extra zeros are added

so total no of zeros are 10 + 11 + 3 =24

**∴ Total no. of zeros are 24 **
