Question

A shopkeeper fixed the price of a pen to make a profit of 10 percent but he sold allowing a discount 7.50 and lost 5 percent . At what price did he purchase the pen

Answer 1

Answer:

Step-by-step explanation:

Let the cost price of the article be CP. And selling price be SP.

Case 1: Profit%= 10%

SP= CP+ (10/100)*CP = 11CP/10.

Case 2: Now if she had sold it for RS.45 more, profit% given is 25%.

SP+45= CP + (25/100)*CP

SP + 45= 5CP/4

Substitute SP = 11 CP/10 in the above equation.

You get CP = RS. 300

So the price of the article is RS. 300.
