Question

A man sells an article at a profit of 25%.if he had bought it at 20% less and sold it for RS. 36.75 less he would have gained 30%.find the cp of the article.

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.
