Fabian is
h years old. Vaidev is six times as old as Fabian and John is 7 years younger than Vaidev.
- Express John's age in terms of h.
- Fabian is 9 years old as of now. ln how many years' time will John be 3 times as old as Fabian?
(a)
Fabian's age =
h years
Vaidev's age = 6
h years
John's age = (6
h - 7) years
(b)
h = 9
Difference in age remains unchanged.
Difference in age between John and Fabian
= (6
h - 7) -
h = 6
h -
h - 7
= 5
h - 7
= 5 x 9 - 7
= 38 years
Difference in the age when John will be 3 times as old as Fabian
= 3 u - 1 u
= 2 u
2 u = 38
1 u = 38 ÷ 2 = 19
Number of years' time so John will be 3 times as old as Fabian
= 19 - 9
= 10 years
Answer(s): (a) (6
h - 7) years; (b) 10 years
