Question

a man sells an article at a profit of 25% if he had brought it 20% less and sold it for 10.50 less, he would have gained 30% find the cost price 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.
