Question
A shopkeeper marks an item 50% above its cost price.
During a sale, he provides two successive discounts of 20% and 10%. Calculate the profit percentage.Solution
Let the Cost Price (CP) = ₹x. Marked Price (MP) = CP × 1.50 (since it's 50% above CP) = 1.5x Selling Price (SP) after two successive discounts of 20% and 10%: SP = 1.5x × (1 - 0.20) × (1 - 0.10) SP = 1.5×0.72x SP = 1.08x
