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
