Question

The selling price of a sofa set is 45 times of
its cost price find the gain or the loss percent

Answer 1

Step-by-step explanation:

Selling price is 4/5 of CP

Let CP = x

SP = 4/5 of x = 4x/5

Cp is greater hence loss

Loss = x - 4x/5 = (5x-4x) / 5 = x/5

Loss percent = loss/cp * 100

= (x/5) / x * 100

= x/5x * 100

= 100/5 = 20%

loss % = 20%

Answer 2

Correct Question : The selling price of a sofa set is 4/5 times or its cost price find the gain or the loss percent.

Let the Cost Price (CP) be x.

Then,

The selling price (SP) will be = 4/5 of x

SP = (4/5) × x

SP = 4x/5

Since, CP is greater than SP, there is loss.

$\boxed{\bold{Loss= CP - SP}}$

Loss = (4x/5) - x

Loss = x/5

As loss is x/5,

Loss% = {(loss/CP)×100}%

= {(x/5x)×100}%

= (100/5)%

= 20%

Therefore, from the above given sofa set we got a loss of 20%.
