Question

If the selling price of 25 balls is equal to the cost price of 15 balls, find the profit or loss percent.​

Answer 1

The loss percentage of ball is 40%

Given,

• selling price SP of balls=Cost price CP of 15 balls.

Now,

We have to find the profit or loss per percentage.

Let us take the cost of 1 ball be 1rs

Then,

• CP of 15 balls=15rs
• CP of 25 balls should be 25rs

To find gain or loss,

Loss=CP-SP

=25-15

=10

Loss%=gain/CP×100

=10/25×100

=40%
