GRE Exam Numerical Ability Profit and Loss

A man purchases 2 watches for Rs. 560.
He sells one at 15% profit and the other at
10% loss. He neither gains nor loses. Thus,
the cost prices of 2 watches are....

Read Solution (Total 3)

Let the price of the 2 watches be x and y.
Thus x+y=560
Now let x be sold at 15% profit and y be sold at 10% loss.
Thus 115x+90y=56000
Or 115x+90(560-x)=56000
Or 115x-90x+50400=56000
Or 25x=5600
Or x=224
Thus y=336

224, 336

If cost price of one watch=x & other=(560-x), then
1.15x + 0.9(560-x)= 560
1.15x+504-0.9x=560 ,x=224, so (560-x)=336
