Question
If a pen is bought at 11/12th of its selling price and
sold at 10% more than its selling price, what will be the percentage profit?Solution
Let the SP = 600 Rs CP = 600 × 11/12 CP = 550 Rs ATQ-if sold at 10% more than its selling price SP = 600 × 110/100 SP= 660 Then Profit = 660-550 = 110 Profit % = (110/550) ×100 = 20%
