Question
A person bought an article and sold it at a loss of 20%.
If he had bought it at 10% less price and sold it for 7400 more, he would have gained 30%. Find the profit percent if he had sold it at Rs 22000.Solution
Let the C.P be Rs x S.P = (x × 80)/100 = Rs 80/100 x Then, New C.P = (x × 90)/100 = Rs 90/100 x New S.P = Rs (90 x)/100× 130/100 = Rs 117/100 x According to question 80/100 x + 7400 = 117/100 x 37/100 x = 7400 ∴ x = (7400 ×100)/37 = Rs 20000 C.P of an article = Rs 20000 S.P of an article = Rs 22000 Profit % = (22000-20000)/( 20000) ×100 = 10%
