Question
The age of person X (x + 1) years ago and the age of
person Y (x + 2) years from now are in the ratio 1:2.Additionally, it is given that:X is 4 years younger than Z.Y is 5 years older than Z.Z will be 34 years old after 5 years.Solution
ATQ;
Given,
(X-(x+1)): (Y+(x+2)) = 1: 2 …(i)
Also, age of Z = 34- 5 = 29 years
So, age of X = 29- 4 = 25 years
Age of Y= 29+5 = 34 years
Now, using equation (i), we get,
(X-(x+1)) : (Y+(x+2)) = 1: 2
(25 – x-1) : (34+x+2) = 1: 2
48 – 2x = 36 + x
3x = 48 – 36
3x = 12
x = 12 ÷ 3 = 4
