Jordan's current age
(Divisible by 6)
(Between 20 to 50)
Therefore possible age: 24,30,36,42 or 48
After 4 years, Jordan's possible age : 28,34,40,36 or 52
Age after 4 years must be divisible by 5. Only 40 is divisible by 5.
Therefore Jordan's age after 4 years must be 40
Jordan's current age is 36.
Hope it helps! :)
