The difference in the age between Reggie and Carl remains unchanged.
Carl's current age = 1 u
Reggie's current age = 1 u + 7
Combined age of Reggie and Johny 13 years ago
= 1 u + 1 u + 7
= 2 u + 7
2 u + 7 = 63
2 u = 63 - 7
2 u = 56
1 u = 56 ÷ 2 = 28
Reggie's current age
= 1 u + 20
= 28 + 20
= 48
Answer(s): 48
