Question

If the cost price of $14$ articles is equal to the selling price of $10$ articles. What is profit per cent?

• A. $18\%$
• B. $20\%$
• C. $40\%$
• D. $80\%$

Answer 1

Answer: (C)

$40\%$

Let cost price of an article $=XRs$

Cost price for 10 articles $=10XRs$

Selling price for 10 articles $=$ Cost Price of 14 articles $=14XRs$ ( Given)

So, Profit $=$ Selling price-Cost price $=14X-10X=4XRs$

$\therefore Profitpercentage=\frac{profit\times 100}{Costprice}=\frac{4x\times 100}{10x}=40\%$
