    I am three times as old as my son. 15 years hence, I will be twice as old as my son. The sum of our ages is

    A)  48 years                      

    B)  60 years  

    C)  64 years          

    D)         72 years

    Correct Answer: B

    Solution :

     Let the son's present age \[=x\]years. \[\therefore \]Father's present age \[=3x\]years After 15 years,             \[3x+15=2(x+15)\] \[\Rightarrow \]   \[3x+15=2x+30\] \[\Rightarrow \]   \[x=30-15=15\] \[\therefore \]Sum of their present ages             \[=x+3x=4x\]             \[=4\times 15=60\] years
