Question 123753
Let the age of Tom be "x" yrs.


Therefore, the age of Tom's father is 3x yrs.


Given that 4 yrs ago, he was 4 times as old as tom. Therfore the equations are:


3x - 4 = 4(x - 4) 


3x - 4 = 4x - 16 


16 - 4 = 4x - 3x


12 = x


Therfore, Tom is 12 yrs old


Hence his father would be 3 times as tom. that is equal to 3(12) = 36 yrs


Hence the solution
