Question

pr
5. A watch was sold at a loss of 10%. If it
was sold for Rs.140 more, there would
have been a gain of 4%. What is the cost
price?​

Answer 1

Explanation:

Given,

Loss is 10%

Suppose the CP is x

Then with the loss of 10% the SP will be

x-10% of x

= 9x/10.

Now according to the question if it was sold for 140 more then the SP is, (9x/10)+140

With gain of 4% on CP the SP will be x+4% of x

SP=26x/25

Now,

26x/25= (9x/10)+140

(26x/25)-(9x/10)=140

7x/50=140

x=(140*50)/7

x=1000.

So the CP is 1000.
