Question
Vishal sold an item for a 25% profit. Later, he reduced
the cost price and selling price of the item by 20% and 10%, respectively, from their original values. What is the percentage profit he makes after these adjustments?Solution
Let, original cost price be Rs. ‘x’. So, original selling price = 125% of x = Rs. 1.25x New cost price = 80% of x = Rs. 0.8x New selling price = 90% of 1.25x = Rs. 1.125x So, new profit percentage = {(1.125x – 0.8x)/0.8x} × 100 = 40.6%
