A man bought oranges at the rate of 8 for Rs. 34 and sold them at the rate of 12 for Rs. 57. How many oranges should be sold to earn a net profit of Rs. 45?

A) 90

B) 100

C) 135

D) 150

Correct Answer: A

Solution :

Let the man buy 24 (LCM of 8 and 12) oranges.

\[\therefore \]CP of 24 oranges \[=\frac{34}{8}\times 24\]= Rs. 102

SP of 24 oranges \[=\frac{57}{12}\times 24\]= Rs. 114

Gain\[=114-102\]= Rs. 12

\[\because \] Rs. 12 = 24 oranges

\[\therefore \] Rs.\[45=\frac{24}{12}\times 45=90\]oranges
