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
