Read Solution (Total 3)
-
- 24 zeroes is the answer.
Irrespective of power of 2 in the product,we just count the power of 5 in the product bcoz the number of 2's are >> than number of 5's
The max power of 5 is 24 - 11 years agoHelpfull: Yes(4) No(0)
- irrespective of power of 2 in the product,we just count the power of 5 in the product because the no of 2's is greater than the number of 5's
[100/5]+[100/5^2]+.....
=>20+4=24 (ans) - 10 years agoHelpfull: Yes(3) No(0)
- 10,20,30,...,100
there are 11 zeros
4*5,14*15,.....94*95
there are 10 zeros
5*2,5*4,5*6,5*8
there are 3 zeros since 5*4 is already counted
So,ans is 24 - 5 years agoHelpfull: Yes(0) No(0)
