The difference in the age between Gabriel and Seth remains unchanged.
Seth's current age = 1 u
Gabriel's current age = 1 u + 6
Combined age of Gabriel and Johny 10 years ago
= 1 u + 1 u + 6
= 2 u + 6
2 u + 6 = 70
2 u = 70 - 6
2 u = 64
1 u = 64 ÷ 2 = 32
Gabriel's current age
= 1 u + 16
= 32 + 16
= 48
Answer(s): 48
