Correct Answer: Rs. 10,000
Solution :
Given: Rajiv sells a book to Mohan at a profit of 9% and Mohan sells it to Gopal at a profit of 13%. Gopal pays Rs. 12,317 for it.
Let the cost price (CP) for Rajiv be $x$.
According to the question,
$x×\frac{100+9}{100}×\frac{100+13}{100}=12317$
⇒ $x=12317×\frac{100}{109}×\frac{100}{113}$
⇒ $x=10,000$
Hence, the correct answer is Rs. 10,000.
