The selling price of 6 articles is equal to the cost price of 7 articles. Find the profit percentage.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → \(16\frac{2}{3}\)%
Profit per cent is always taken on the cost price. Comparing the same number of articles (6) gives the cost and the selling price directly.
Let the cost price of one article be Rs 1
Cost price of 6 articles \(=\) Rs 6
Selling price of 6 articles \(=\) cost price of 7 articles \(=\) Rs 7
Profit \(=7-6=\) Rs 1
Profit % \(\displaystyle =\frac{1}{6}\times100=16\frac{2}{3}\%\)
The profit is \(16\frac{2}{3}\)%.
