Question

If $5$% more is gained by selling an article for Rs. $700$ than by selling it for Rs. $680$, the cost of the article is:

• A. $300$
• B. $400$
• C. $500$
• D. $600$

Answer 1

Answer: (B)

$400$

$Profit=Rs.700-Rs.680=Rs20$

Gain % = $\frac{20\times 100}{CP}$

$\Rightarrow CP=\frac{20\times 100}{5}=Rs.400$
