If the cost price of 70 articles is equal to the selling price of 40 articles, what will be the profit percentage?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 75%
Let the cost price of one article = x
And, the selling price be y.
Given, 70x = 40y
⇒ y/x = 7/4
If cost price is Rs 4, then the selling price would be Rs 7
Profit = Rs 3
Profit percentage = (3/4) × 100 = 75%
