    A piece of wire 78 cm long is bent in the form of an isosceles triangle. If the ratio of one of the equal sides to the base is \[5:3,\] then what is the length of the base?

    A)  \[16\text{ }cm\]                        

    B)  \[18\text{ }cm\]

    C)  \[\text{20 }cm\]                        

    D)  \[\text{30 }cm\]

    Correct Answer: B

    Solution :

     Let each equal side \[=5x\text{ }cm\] and the base = \[3x\text{ }cm\] then, \[5x+5x+3x=78\Rightarrow x=\frac{78}{13}=6\] Length of base \[=3\times 6=\]
