29

Did it by enumeration ... not sure if this is the best way to solve this kinda problem.

1...10 2 zeros .... 2*5 and 10
11..20 2 zeros ..... same logic
21..25 2 zeros ..... 25 is 5 times 5 ... hence 1 zero comes from 22*5 and the other zero comes from 24*5

Hence we get the 6 zeros needed and highest value of n is 29
