Question

a man buys toffees at 10 for rupees 3 and sells them at 8 for rupees 3 find his gain percent

Answer 1

hence the gain percent is 25%

Answer 2

Find the cost price of 1 toffee:

10 toffees = Rs 3

1 toffee = 3 ÷ 10 = Rs 0.30

Find the selling price of 1 toffee:

8 toffees = Rs 3

1 toffee = 3 ÷ 8 = Rs 0.375

Find the gain:

Gain = Selling Price - Cost Price

Gain = 0.375 - 0.3 = Rs 0.075

Find the gain percentage:

Gain Percentage = gain/cost price x 100

Gain Percentage = 0.075/0.3 x 100 = 25%

Answer: The gain is 25%
