    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
