Glen is
r years old. George is six times as old as Glen and Asher is 6 years younger than George.
- Express Asher's age in terms of r.
- Glen is 9 years old as of now. ln how many years' time will Asher be 4 times as old as Glen?
(a)
Glen's age =
r years
George's age = 6
r years
Asher's age = (6
r - 6) years
(b)
r = 9
Difference in age remains unchanged.
Difference in age between Asher and Glen
= (6
r - 6) -
r = 6
r -
r - 6
= 5
r - 6
= 5 x 9 - 6
= 39 years
Difference in the age when Asher will be 4 times as old as Glen
= 4 u - 1 u
= 3 u
3 u = 39
1 u = 39 ÷ 3 = 13
Number of years' time so Asher will be 4 times as old as Glen
= 13 - 9
= 4 years
Answer(s): (a) (6
r - 6) years; (b) 4 years
