d years old. Cody is six times as old as Ryan and Albert is 14 years younger than Cody.
- Express Albert's age in terms of d.
- Ryan is 8 years old as of now. ln how many years' time will Albert be 3 times as old as Ryan?
(a)
Ryan's age =
d years
Cody's age = 6
d years
Albert's age = (6
d - 14) years
(b)
d = 8
Difference in age remains unchanged.
Difference in age between Albert and Ryan
= (6
d - 14) -
d = 6
d -
d - 14
= 5
d - 14
= 5 x 8 - 14
= 26 years
Difference in the age when Albert will be 3 times as old as Ryan
= 3 u - 1 u
= 2 u
2 u = 26
1 u = 26 ÷ 2 = 13
Number of years' time so Albert will be 3 times as old as Ryan
= 13 - 8
= 5 years
