Question
Roshan purchased 100 rolls of paper for Rs. 25 per roll.
He spent Rs. 500 on their transportation. He also paid 30 paise per roll for packing of each roll. At what price must he sell each roll to gain 20% overall?Solution
Effective cost price of 100 rolls of paper = (100 × 25) + 500 + (100 × 0.3) = 2500 + 500 + 30 = Rs. 3030 Selling price at 20% profit = 1.20 × 3030 = Rs. 3636 Therefore, selling price of each roll of paper = 3636/100 = Rs. 36.36
