Question 128

On selling an article for ! 170, a shopkeeper loses 15%. In order to gain 20%, he must sell that article at rupees:

Solution

Original S.P. = 170

Loss % = 15%

Let C.P. = $$x$$

=> $$\frac{x - 170}{x} * 100 = 15$$

=> $$17x = 3400 => x = 200$$

Profit % = 20%

=> Profit amount = $$\frac{20}{100}$$ * 200 = 40

New S.P. = 200+40 = 240
