    If\[x=\frac{y}{3}=\frac{z}{4}={{25}^{o}}\], then the value of \[x+y+z\] is

    A) \[{{100}^{o}}\]                                  

    B) \[{{300}^{o}}\]

    C) \[{{200}^{o}}\]                                  

    D) \[{{400}^{o}}\]

    Correct Answer: C

    Solution :

     \[x=\frac{y}{3}=\frac{z}{4}={{25}^{o}}\] \[\therefore x=25,\frac{y}{3}={{25}^{0}},\frac{z}{4}={{25}^{o}}\] \[y={{75}^{o}},\,\,z={{100}^{o}}\] Hence\[x+y+z={{25}^{o}}+{{75}^{o}}+{{100}^{o}}={{200}^{o}}\]
