    A)  3

    B)                                 4  

    C)         5                    

    D)         6

    Correct Answer: B

    Solution :

            \[\frac{(x+2)\times 60+x\times 120+(x-2)\times 180}{(x+2)+x+(x-2)}=100\]             \[\Rightarrow \]   \[\frac{360x-240}{3x}=100\]             \[\Rightarrow \]   \[60x=240\Rightarrow x=4\]
