Question
If on a marked price, the difference between the
selling price at a discount of 40% and that at two successive discounts of 20% and 10% is Rs. 132. Find the marked price of the article?Solution
Let the MP be x In the first case, SP at 40% loss = 60x/100 Single discount equivalent to 20% and 10% successive discounts = (20+10-(20 × 10)/100) = 28% SP in the second case = 72x/100 Now, 72x/100 - 60x/100 = 132 12x/100 = 132 x = (100×132)/100 = Rs. 1100
