The difference in the age between Riordan and Neave remains unchanged.
Neave's current age = 1 u
Riordan's current age = 1 u + 12
Combined age of Riordan and Johny 13 years ago
= 1 u + 1 u + 12
= 2 u + 12
2 u + 12 = 66
2 u = 66 - 12
2 u = 54
1 u = 54 ÷ 2 = 27
Neave's current age
= 1 u + 13
= 27 + 13
= 40
Answer(s): 40
