Explanatory Answer

Method of solving this CAT Question from Profit and loss: Relating the profit percent with the selling price is the key here.

Let the C.P. be x and S.P. be y.
∴ Given,
3(y-x) = 2y – x
=> 3y – 3x = 2y – x
=> y = 2x
Original profit = Rs y – x
= Rs 2x – x (Since, y = 2x)
= Rs x
∴ Original profit % = x/x ∗ 100
= 100 %

The question is "Find the original profit percent."
The original profit percent is 100%

Hence, the answer is 100%.

Choice B is the correct answer.
