Question

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

Answer 1

Answer:

Step-by-step explanation:

Hey

Sp of 25 balls=cp of 15 balls

Let cost price of 1 ball be 1rs

Then cp of 15 ball is 15 rs

Now,

Cp of 25 ball should be 25 rs

But here so of 25 ball is equal to cp of 15 ball that is 15 rs

Loss is equal to cp-sp

25-15=10rs loss

Loss% is loss*100/cp

10*100/25

40%loss

Answer 2

Answer:

The loss percentage of the balls is 40%​

Step-by-step explanation:

Given,

• Selling price 'SP' of 25 balls = Cost price 'CP' of 15 balls

Now,

we have to find the profit or loss percentage.

Let us take the cost price of 1 ball be 1rs

Then,

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

But here,

• SP of 25 = CP of 15 balls
• and the cost of SP is 15 rs.

To find gain or loss,

loss = CP - SP

       = 25 - 15

       = 10

loss % = $\dfrac{gain}{CP}\times100$

           = $\dfrac{10}{25}\times100$

           = 40%
