Question

The cost price of 10 apples is equal to the selling price of 9 apples. Find the loss or gain
percentage.​

Answer 1

Answer:

11.11%

Step-by-step explanation:

let the c.p of 10 apple be x.

Then, selling price of 9 apples ( SP) = ₹ x (given)

Cost price of 9 apples (CP)= x * 9 / 10 = 9x /10

sold 9 apples out of 10 apples for the same cost.

=> profit

therefore profit % = (s.p -c.p) of 9apples *100 / c.p of 9 apples

                             = { [x - (9x/10)]*100 } / (9x/10)

                             = { [(10x-9x)]*10 } * (10/9x)

                             = {x*10 } * (10/9x)

                             =(10x*10)/9x

                             = 100/9

                             = 11.11 %
