The difference in the age between Liam and Lee remains unchanged.
Lee's current age = 1 u
Liam's current age = 1 u + 11
Combined age of Liam and Johny 12 years ago
= 1 u + 1 u + 11
= 2 u + 11
2 u + 11 = 69
2 u = 69 - 11
2 u = 58
1 u = 58 ÷ 2 = 29
Liam's current age
= 1 u + 23
= 29 + 23
= 52
Answer(s): 52
