Question

A man loses the selling price of 4 apples upon selling 36 apples. His loss percent is

Answer 1

Let the sp be x
Sp of 8 aaples=rs.36x
Sp of 4 aaples=rs.4x
Lost amount==sp of 4 apples=4x

Cp of 36 apples=sp+loss
=36x+4x
=40x

Loss%=loss/cp×100
=4x/40x×100
=10%

Answer 2

Answer:

His loss percent is 10%.

Step-by-step explanation:

It is given that a man loses the selling price of 4 apples upon selling 36 apples.

Loss on 36 apples is equal the the selling price of 4 apples.

loss × 36 = selling price × 4

$\frac{loss}{SP}=\frac{4}{36}=\frac{1}{9}$

It means the ratio of loss and selling price is 1:9.

Let the loss be x and selling price be 9x.

Cost price of apple is

$CP=SP+loss$

$CP=9x+x=10$

Loss percentage is

$loss\%=\frac{loss}{CP}\times 100$

$loss\%=\frac{x}{10x}\times 100=10\%$

Therefore his loss percent is 10%.
