Question

The ratio between the sale price and cost price of an article is $7:5$. What is the ratio between the profit and the cost price of that article ?

• A. $2:7$
• B. $5:2$
• C. $7:2$
• D. $2:5$

Answer 1

The correct option is D $2:5$

The ratio between the sale price and cost price of an article is $7x:5x.$

Then the profit becomes $7x-5x$ which is $2x$.

So, the ratio between profit and cost price is $2x:5x$ or $2:5$.
