(a)
Jeremy's age =
n years
Daniel's age = 5
n years
Dylan's age = (5
n - 4) years
(b)
n = 4
Difference in age remains unchanged.
Difference in age between Dylan and Jeremy

n - 4) -
n = 5
n -
n - 4
= 4
n - 4
= 4 x 4 - 4
= 12 years
Difference in the age when Dylan will be 3 times as old as Jeremy

= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
