Question

A man sells an article at a profit of Rs 20%. If he had bought it at 10% less and sold it for Rs 18 more, he would have gained 40%. Find the cost price of the article?

Answer 1

Answer:

Step-by-step explanation:

Let C.P =100

Gain =20%

S.P = 100 + 25% of 100 = 120

Supposed C.P =80

Gain =40%

S.P =(140*80)/100=112

Difference =(120-112) = 8

Now comparing difference

8 on 100

1 on 100/8

So, 18 on = (18*100)/21 = 87.571 (approx)

So, required C.P = Rs. 87 .
