    A father tells his son, "I was of your present age when you were born." If the father is 36 now, how old was the boy five years back?

    A)  13       

    B)  15

    C)  17                               

    D)  20

    Correct Answer: A

    Solution :

    Let the father's age be x and the sons's age be y. Then, \[x-y=y\] or \[x=2y\] Now, \[x=36,\] So \[2y=36\] or \[y=18.\] \[\therefore \] Son's present age = 18 yr. So, son's age 5 yr ago\[=13\,yr.\]
