C) 16
D) 15
Correct Answer: B
Solution :
Symmetric about \[x=4\] \[2\left\{ \left[ \frac{{{x}_{1}}+{{x}_{2}}}{2} \right]+\left[ \frac{{{x}_{3}}+{{x}_{4}}}{2} \right]+\left[ \frac{{{x}_{5}}+{{x}_{6}}}{2} \right]+\left[ \frac{{{x}_{7}}+{{x}_{8}}}{2} \right] \right\}\]\[=2\,\{4+4+4+4\}=16\times 2=32\]You need to login to perform this action.
