arithmetic - 1 year ago a father was four times as old as his son muni in 6 years time his age exceeds twice the munis age by 9 years ratio of their ages is - skillgun

Let the present ages of father and son be x and y years, respectively
Then, (x - 1) = 4(y -1)
or, 4y - x = 3 ..(1)
and, (x + 6) - 2(y + 6) = 9
or, -2y + x = 15 ..(2)
Solving (1) and (2), we get , x = 33, y = 9
Ratio of their ages = 33 : 9 = 11 :3
