    A boy's age is one fourth of his father's age. The sum of the boy's age and his father's age is 35. What will be father's age after 8 years?

    A)  15                   

    B)  28

    C)  35                   

    D)       36

    Correct Answer: D

    Solution :

     Let father's age is \[x\]      \[\frac{1}{4}x+x=35\]     or \[\frac{\cancel{5\,}x}{4}={{\cancel{35}}^{7}}\]     or \[x=28\] Father's age after 8 years \[=x+8\]                                        \[=28+8=36\] years
