(2) Smart Tip: In this question, actualC.P. is not necessary. Thisquestion is all about finding overallpercentage change when there is apercentage increase and a percentagedecrease in succession.Thus, we can take any convenientvalue of C.P. Let C.P. = ₹ 100 Markup = 80% of 100 = ₹ 80 ⇒M.P. = 100 + 80 = ₹ 180 After the discount of 35%, S.P. = 180 – 35% of 180 = 180 – 63 = ₹117 Profit = 117 – 100 = ₹ 17 Since the shopkeeper has a profitof ₹ 17 on ₹ 100 ∴Profit percentage = 17%
