Roshan purchased 100 rolls of paper for Rs. 22 per roll.
He spent Rs. 300 on their transportation. He also paid 10 paise per roll for packing of each roll. At what price must he sell each roll to gain 30% overall?Solution
Effective cost price of 100 rolls of paper = (100 × 22) + 300 + (100 × 0.1) = 2200 + 300 + 10 = Rs. 2510 Selling price at 30% profit = 1.30 × 2510 = Rs. 3263 Therefore, selling price of each roll of paper = 3263/100 = Rs. 32.63
