The difference in the age between Daniel and Julian remains unchanged.
Julian's current age = 1 u
Daniel's current age = 1 u + 11
Combined age of Daniel and Johny 8 years ago
= 1 u + 1 u + 11
= 2 u + 11
2 u + 11 = 55
2 u = 55 - 11
2 u = 44
1 u = 44 ÷ 2 = 22
Daniel's current age
= 1 u + 19
= 22 + 19
= 41
Answer(s): 41
