    A) 10 yr                

    B) 15 yr

    C) 20 yr

    Correct Answer: D

    Solution :

    Let present age of man be x yr.

    \[x+15=4\,\,(x-15)\]
    \[\Rightarrow \]   \[x+15=4x-60\]\[\Rightarrow \]\[3x=75\]
    \[\therefore \]      \[x=25\,\,yr\]
    Hence, the present age of man is 25 yr.
