Question

SP of 9 apples is equals to the CP of 15 apples.Find gain percent

Answer 1

Answer:

Gain = 66.67 per cent

Step-by-step explanation:

All the calculations will be made with respect to ONE apple

Let CP of 1 apple = x

=> CP of 15 apples = 15x

ATQ, SP of 9 apples = CP of 15 apples

=> SP of 9 apples = 15x

=> SP of 1 apple = (15/9)x

Profit = SP - CP

= (15/9)x - x

= [(15/9) - 1]x

= (6/9)x

Profit for 1 apple = (6/9)x

Profit% = 100*(Profit)/CP

            = 100*(6/9)x ÷ x

            = 100*(6/9)

            = 100*(2/3)

            = 66.67 (approx)

Profit% = 66.67 per cent
