    The present age of a father is 3 yr more than three times the age of his son. Three years hence, father's age will be 10 yr more than twice the age of the son. The father's present age is

    A)  33 y                

    B)  39 yr

    C)  45 yr                           

    D)  40 yr

    Correct Answer: A

    Solution :

    Let the son's present age \[=x\,yr\] \[\therefore \] Father's age \[=(3x+3)yr\] After 3 yr, \[\Rightarrow \]   \[(3x+3)+3=2(x+3)+10\] \[\Rightarrow \]          \[36+6=2x+16\] \[\Rightarrow \]               \[x=10\] \[\therefore \]      Father's present age \[=3x+3\]             \[=3\times 10+3=33\,\,yr\]
