Question

if the selling price of 25 balls is equal to the coast price of 15 balls find the profit or the loss percentage

Answer 1

percentage of loss is 40%

Step-by-step explanation:

let CP of one ball be =1

CP of 15 ball = 15

CP of 25 ball = 25

Given,

CP of 15 balls= SP of 25 balls

so, SP of 25 balls= 15

loss = CP-SP

=25-15

=10

percentage of loss= loss/CP *100

=10/25 *100

=40%

Answer 2

Given: Selling Price of 25 balls= Cost Price of 15 balls

To Find: Profit or Loss percentage

Solution: Let us assume that,

CP of one ball= Rs.1                               [CP=Cost Price, SP=Selling Price]

CP of 15 balls= Rs. 15.

Given that, SP of 25 balls=CP of 15 balls

Therefore, SP of 25 balls=Rs.15.

Since, CP of 25 balls is more than SP than of 25 balls, hence there is loss

Loss=CP-SP

Loss=Rs.25-Rs.15 [CP of 25 balls=Rs.25]

       =Rs.10.

Loss Percentage=Loss/CP* 100

                           =10/25*100

                           =40%

Answer:- The loss percentage is 40%.
