Question

a man sold an article at a loss of 25%. if he sells the article for rs. 21 more, he would have got a gain 10%. the cp of the article Is?

Answer 1

Let C.P =100

Gain =25%

S.P = 100 + 25% of 100 = 125



Supposed C.P =80

Gain =30%

S.P =(130*80)/100=104

Difference =(125-104) =21



Now comparing difference

21 on 100

1 on 100/21

So, 10.50 on = (10.50*100)/21 = 50.

So, required CP = Rs. 50.
