Give answer in approx

OPtion

1) 27
2) 30
3) 34
4) 37
5) 43
6) 44
7) 45
8) 47
9) 48
10) none of these

Solution

let the initial investment = 100
so after first year of loss remaining amount = 100-27 = 73
let the profit factor (profit percent/100) = x
so according to the given condition
73(1+x) = 100
or 1+x = 100/73
or x = 100/73 - 1 = 27/73 = 0.3699
means 36.99 = 37 %
