Question

Jai Narayan sells two radio sets for 2288® each .on one he gains10% and on other he loses 10% .find his gain or loss per cent

Answer 1

Answer:

1% loss

Step-by-step explanation:

Cp of 1st = x

Gain 10% = (10{100)x = 0.1x

x +0.1x = 2288

1.1x = 2288

x = 2288/1.1 = 2080

Cp of other = y

Loss = (10/100)y = 0.1y

y -0.1y = 2288

0.9y = 2288

y = 2288/0.9 = 2542.22

Cp of both = 2080 + 2542.22 = 4622.22

Selling price of both = 2288×2 = 4576

Loss = 4622.22-4576 = 46.22

Loss % = (46.22 /4622.22)×100 = 1%

Answer 2

when there is increase in 10 % and again decrease in 10 % finally there will be 10% decrease
