Problem
Solution 1
We use the distributive property to get ![\[3\times 4+2\times 4+2\times 3 = 26 \rightarrow \boxed{\text{E}}\]](http://latex.artofproblemsolving.com/6/9/6/696057855d9d7437bb8c492ee09749c3a843647f.png)
Solution 2
Since 
, we have ![\[(2\times 3\times 4)\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{4}\right) > 2\times 3\times 4 \times 1 = 24\]](http://latex.artofproblemsolving.com/7/3/f/73fb09048546749e763867c37a9daf9b86e9a9df.png)
The only answer choice greater than 
is 
.
Solution 3(Bash)
