A) 14
B) 21
C) 22
D) 48
Correct Answer: A
Solution :
[a] Factors of \[336={{2}^{4}}\times 3\times 7\] Factors of \[240={{2}^{4}}\times 3\times 5\] Factors of \[96={{2}^{5}}\times 3\] HCF \[=(24\times 3)=48\] So, we make stacks of 48 books each. Number of stacks \[=\left( \frac{336}{48}+\frac{240}{48}+\frac{96}{48} \right)\] \[=(7+5+2)=14\] |
