The cost price 15 articles is equal to the selling price of 20 articles. Find the loss percentage.
Answer & explanation
Correct answer: option 4
Cost price of 15 articles = Selling price of 20 articles
Assume cost price of 1 article be 'x'
cost price of 15 article = 15x
Cost price of 20 articles = 20x
But, originally Selling price of 20 articles = 15x
Loss = Cost price of 20 articles-Selling price of 20 articles = 20x-15x = 5x
Loss% = Loss×100/Cost price of 20 articles = 5x × 100/20x = 25%
The correct answer is Option (4) → 25%
