(a)
Reggie's age =
d years
Glen's age = 5
d years
Warren's age = (5
d - 12) years
(b)
d = 9
Difference in age remains unchanged.
Difference in age between Warren and Reggie
= (5
d - 12) -
d = 5
d -
d - 12
= 4
d - 12
= 4 x 9 - 12
= 24 years
Difference in the age when Warren will be 3 times as old as Reggie
= 3 u - 1 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of years' time so Warren will be 3 times as old as Reggie
