If the cost price of 15 articles is equal to the selling price of 12 articles, what is the profit percent?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 25%.
Let cost price (CP) of 1 article = ₹1
Then, CP of 15 articles = ₹15
Given: CP of 15 articles = SP of 12 articles
⇒ SP of 12 articles = ₹15
So, SP of 1 article = 15 / 12 = ₹1.25
Profit per article = 1.25 − 1 = ₹0.25
Profit % = (0.25 / 1) × 100 = 25%
