Question

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

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

The correct option is C 5

C.P. of 6 toffees = Rs. 1
S.P. of 6 toffees = $120\%$ of Rs. 1 = Rs. $\frac{6}{5}$
For Rs. $\frac{6}{5}$, number of toffees sold = 6.
For Rs. 1, number of toffees sold $=(6\times \frac{5}{6})=5$.
