Question
A person 'X' is 8 years younger than 'Y' and also 13 years
less than twice the age of 'Z'. Given that the ages of 'Y' and 'Z' are in the ratio 5:3, determine the current age of 'X'.Solution
ATQ;
Let 'Y' = 5x, and 'Z' = 3x
'X' = 'Y' – 8 = 5x – 8
Also, 'X' = 2('Z') – 13 = 2(3x) – 13 = 6x – 13
Hence, 5x – 8 = 6x – 13
x = 5
'X' = 5(5) – 8 = 25 – 8 = 17
