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

11.06 2 – 7.12 × 4.88 + 9.96 = 12.22 × ?
1456.92 + ? – 1324.87 = 1875.34 – 1683.29
(359.92÷24.02)+(230.04÷5)=?% of 210.0-86.1
(20.98 ÷ 2.91) + (15.12 – 5.96) = ?
