If the father is 60 years old and the son is half his age, the son is currently 30 years old. When the father was four times the son's age, he would have been 40 years old (since 40 is four times 10). At that time, the son was 10 years old. Thus, the boy was 10 years old when his father was four times his age.
He will never reach that exact age.In four years' time they will be 26 and 6 so that Mr Walker will be 4.33... times his son's age, or 3.33... times older than his son. In five years' time they will be 27 and 7 so that Mr Walker will be 3.86... times his son's age, or 2.86... times older than his son.
Suppose your age now is Y So 3*(Y + 3) + 4*(Y + 4) = 8*Y That is, 3Y + 9 + 4Y + 16 = 8Y or 7Y + 25 = 8Y so that Y = 25 In two years time you will be Y + 2 = 27

Let x be Kate's age. In 4 years, 3 times her age is 57 So first , in 4 years, she will be x+4 years old Now 3 times that is 3(x+4)= 3x+12 and that is 57 so 3x+12=57 or 3x=57-12=45 x=45/3=15 So she is 15 years old Let's check. In 4 years she is 19 and 19 times 3 is 57.
