Question
Ravi purchased an item at a 25% reduction from its
listed price and later sold it with a 10% reduction from the same price. What was Ravi's profit percentage from this transaction?Solution
Let the marked price of the article be Rs. '100x' So, cost price for Ravi = 100x X 0.75 = Rs. '75x' And selling price for Ravi = 100x X 0.9 = Rs. '90x' So, gain percentage = {(90x - 75x) /75x} X 100 = 20% Hence, option c.
