ATQ, Assume the cost of article is x the person sold at 20% loss Loss % = (C.P - S.P)/C.P = ((x - S.P)/x) = S.P = (20/100) S.P = 0.8x If he had sold it for Rs. 12 more, then he would have gained 10%. Gain % = (S.P - C.P)/C.P = [[(0.8x + 2,000)- x]/x] = 20/100 20x = 80x + 2,00,000 - 100x 40x = 2,00,000 x = 5,000
