- Express Jeremy's age in terms of g.
- Cole is 7 years old as of now. ln how many years' time will Jeremy be 3 times as old as Cole?
(a)
Cole's age =
g years
Bobby's age = 6
g years
Jeremy's age = (6
g - 9) years
(b)
g = 7
Difference in age remains unchanged.
Difference in age between Jeremy and Cole

g - 9) -
g = 6
g -
g - 9
= 5
g - 9
= 5 x 7 - 9
= 26 years
Difference in the age when Jeremy will be 3 times as old as Cole

= 2 u
2 u = 26
1 u = 26 ÷ 2 = 13
Number of years' time so Jeremy will be 3 times as old as Cole
