1) 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 CExplanation:Let S.P = Rs. x. New S.P = Rs. x2, Loss = 30%. So, C.P = Rs. (10070×x2) = Rs. 5x7. Profit = Rs. (x−5x7) = Rs. 2x7 ∴ Profit% =(2x7×75x×100)% =40%
