Question

Toffees are bought at the rate of 6 for Rs. 30 and sold at 5 for Rs. 30. Find the gain

percentage.
​

Answer 1

If 7 toffees are bought for Re.1, the CP (cost price) of each toffee is Re.1/7.

If 5 toffees are sol for Re.1, the SP (selling price) of each toffee is Re.1/5.

The gain is Re.(1/5) - (1/7) or Re. 2/35 and the gain percent is (2/35)*100/(1/7)

= (2*7/35*1)*100 = 1400/35 = 40%.
