Question
If there is a loss of 20% on selling the article at 16/27 of the original selling price then what will be the percentage profit after selling the article at original selling price?
Solution
Let the original selling price be Rs. 27x New selling price = (16/27) × 27x = Rs. 16x Now, cost price of the article = 16x/0.8 = Rs. 20x Required profit percent = [(27x – 20x)/20x] × 100 = 35%
