The difference in the age between Luis and Ken remains unchanged.
Ken's current age = 1 u
Luis's current age = 1 u + 6
Combined age of Luis and Johny 8 years ago
= 1 u + 1 u + 6
= 2 u + 6
2 u + 6 = 56
2 u = 56 - 6
2 u = 50
1 u = 50 ÷ 2 = 25
Luis's current age
= 1 u + 14
= 25 + 14
= 39
Answer(s): 39
