A) 14        

B) 22    

C) 21                                

D) 48

Correct Answer: A

Solution :

Number of books in each stack = HCF (336, 240, 96)

\[\therefore \]Number of books in each stack \[=48\]

\[\therefore \]Total number of stacks \[=\frac{336}{48}+\frac{240}{48}+\frac{96}{48}\]

\[=7+5+2=14\]
