Question

If percentage of profit made, when an article is sold for $Rs.78$, is twice as when it is sold for $Rs.69$, the cost price of the article is

• A. $Rs.49$
• B. $Rs.51$
• C. $Rs.57$
• D. $Rs.60$

Answer 1

Answer: (D)

$Rs.60$

Let $CP$ be $Rs.x$.
According to the question,

$(78-x)=2(69-x)$
$78-x=138-2x$

$\Rightarrow x=138-78=60$.

Hence, $CP=Rs.60$.
