At what profit percent must an article be sold so that by selling at half that price, there may be a loss of 30% ?


A) 25%

B) 36%

C) 40%

D) 42%

E) 52%

Answer:

Option C

Explanation:

Let S.P = Rs. x. New S.P = Rs. x2, Loss = 30%.

So, C.P = Rs. (10070×x2)

= Rs. 5x7.

Profit = Rs. (x5x7) = Rs. 2x7

Profit% =(2x7×75x×100)%

=40%
