Question
Virendra makes a profit of Rs. 134 if he sells a
certain number of charts papers, he has at the price of Rs. 12 per chart paper and incurs a loss of Rs. 46, if he sells the same number of chart papers for Rs. 8 per chart paper. What should be the selling price of all the chart papers in order to make a profit of 17%?Solution
Let number of chart papers be ‘x’ Profit = 134 Selling price = 10 x Cost price = SP – Profit = 12 x – 134 Similarly, selling price = 8x Loss = 46 Cost price = SP + loss = 8x + 46 Equating two cost prices 12x – 134 = 8x + 46 12x – 8x = 46 + 134 4x = 180 x = 45 Total cost price = 8 × 45+ 46= Rs. 406 In order to make a profit of 17%, selling price = 406 + (17% of 406) = 406 + 69.02 = Rs. 475.02
