1 % of 2% of 3 % of ..........of (n-1) % of n = 720/[(100)^(n-1)]
then n =

OPtion

1) 4
2) 6
3) 11
4) 23
5) 99
6) 125
7) 200
8) 720
9) it is not possible to get any value
10) none of these

Solution

(1/100)[(2/100)[(3/100)[(4/100).....[((n-2)/100)[((n-1)/100)n]].....]]] = 720/[100^(n-1)
so 1*2*3*4...........*n = 720
so n = 6
