A farmer bought toffees at 6 for a rupee. How many for a rupee must he sell to gain 20% ?

A. 7

B. 6

C. 5

D. 2

Answer : C. 5


Explanation:


    Cost Price(C.P) of 6 toffees = Re. 1
    Selling Price(S.P) of 6 toffees = 120% of Re. 1
    = Rs. 6/5
    For Rs. 6/5 toffees sold = 6.
    For Re. 1, toffees sold = 6 x 5/6
    = 5.
