Question
A seller sold some pens at a 24%
discount, resulting in a loss of 5%. If he had sold the pens for Rs. 30 more, he would have made a profit of 20%. What is the cost price of the pens?Solution
ATQ,
Let the marked price of the pen be Rs. '100x' Selling price of the pen = 100x X 0.24 = Rs. '76x' And, cost price of the pen = 76x ÷ 0.95 = Rs. '80x' ATQ; 76x + 30 = 80x X 1.2 Or, 76x + 30 = 96x Or, 30 = 20x So, x = 1.5 So, cost price of the pen = 80 × 1.5 = Rs. 120
