i years old. Flynn is five times as old as Fabian and Rael is 4 years younger than Flynn.
- Express Rael's age in terms of i.
- Fabian is 4 years old as of now. ln how many years' time will Rael be 3 times as old as Fabian?
(a)
Fabian's age =
i years
Flynn's age = 5
i years
Rael's age = (5
i - 4) years
(b)
i = 4
Difference in age remains unchanged.
Difference in age between Rael and Fabian
= (5
i - 4) -
i = 5
i -
i - 4
= 4
i - 4
= 4 x 4 - 4
= 12 years
Difference in the age when Rael will be 3 times as old as Fabian
= 3 u - 1 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Number of years' time so Rael will be 3 times as old as Fabian
