Arif incurred a loss of 25% by selling a used mobile phone set at taka How much could he gain/loss by selling it at 2,200 taka?

A 10% loss

B 20% gain

C 10% gain

D 20% loss

Solution

Correct Answer: Option C

25% loss means 75% of the original price.

75% = 1500

100% = 1500*100/75 = 2000 tk

Now,

2000 tk = 100%

then, 2200 tk = 100*2200/2000

= 110%

Now, gain is = 110 - 100 = 10%
