Question

the selling price of a sofa set is 4 / 5 times of its CP. Find the gain or the loss as percent. Fast I want the answer as soon as possible.

Answer 1

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%
