    Six years hence a father's age will be three times his son's age and three years ago father was nine times as old as his son. What is the present age of father?

    A) 48 yr                

    B) 42 yr

    C) 36 yr                            

    D) 30 yr

    Correct Answer: D

    Solution :

    Let the present age of son \[=x\,yr\] And die present age of father \[=y\,yr\] By given condition, \[(y+6)=3(x+6)\] \[\Rightarrow \]   \[3x-y=-12\]                               ?(i) and       \[y-3=9(x-3)\] \[\Rightarrow \]   \[9x-y=24\]                                ?(ii) On solving Eqs. (i) and (ii), we get \[x=6\,yr\] and \[y=30\,yr\] Then, the present age of father is 30.
