The difference in the age between Tim and Albert remains unchanged.
Albert's current age = 1 u
Tim's current age = 1 u + 11
Combined age of Tim and Johny 13 years ago
= 1 u + 1 u + 11
= 2 u + 11
2 u + 11 = 65
2 u = 65 - 11
2 u = 54
1 u = 54 ÷ 2 = 27
Albert's current age
= 1 u + 13
= 27 + 13
= 40
Answer(s): 40
