    A father's age is 7 times as old as his son. Two year ago, the father was 13 times as old as his son. What are their present ages? (Son and father respectively)

    A)  6, 24                           

    B)  8, 32           

    C)  4, 28

    D)  9, 36

    Correct Answer: C

    Solution :

    (c): \[x\And y\] be ages Then, x = 7y \[\left( x-2 \right)=13\left( y-2 \right)\] \[\Rightarrow 7y-2=13y-26\] \[\Rightarrow 24=6y=y=4\] \[\therefore x=28.\]
