Answer 1

Given :

Toffees are bought at 7 for a Rupee and sold at 5 for a rupee

To find :

Gain or Loss percentage.

Solution :

Finding the CP of 1 toffee :-

7 toffees = ₹ 1

1 toffee = ₹ 1/7

Finding the SP of 1 toffee :-

5 toffees = ₹1

1 toffee = ₹ 1/5

CP = ₹ 1/7 and SP = ₹ 1/5

SP is more so Gain occurred.

Finding the Gain :-

Gain = SP - CP

Gain = 1/5 - 1/7

Gain = (7-5)/35

Gain = 2/35

Finding Gain Percentage :-

Gain percentage = (Gain÷CP) x 100

Gain Percentage = (2/35÷1/7) x 100

Gain Percentage = (14/35) x 100

Gain Percentage = 40℅

Hence, Gain Percentage = 40%
