Since s/t = 64.12
let s = 6412 and t = 100
Here the remainder will be 12
divide s & t by 2
so, s = 3206 and t = 50,
Here the remainder will be 6
again divide s & t by 2
so, s = 1603 and t = 25,
Here the remainder will be 3
as you can see, the remainders are multiple of 3, and the only option that satisfies this criteria is 45.
