Marks: +1, -0

A businessman sells an old machine for Rs. 1150 after taking some profit. Had he sold it for Rs. 910 his loss would have been

7 /5

of the profit. What was the cost price of that machine?

Solution:

Let his C.P. = Rs. x; then

7/5(1150-x)=x-910

⇒ 8050 - 7x = 5x - 4550

⇒12x = 12600

∴ x = Rs. 1050
