Lee is
s years old. Vaidev is six times as old as Lee and Caden is 10 years younger than Vaidev.
- Express Caden's age in terms of s.
- Lee is 8 years old as of now. ln how many years' time will Caden be 3 times as old as Lee?
(a)
Lee's age =
s years
Vaidev's age = 6
s years
Caden's age = (6
s - 10) years
(b)
s = 8
Difference in age remains unchanged.
Difference in age between Caden and Lee
= (6
s - 10) -
s = 6
s -
s - 10
= 5
s - 10
= 5 x 8 - 10
= 30 years
Difference in the age when Caden will be 3 times as old as Lee
= 3 u - 1 u
= 2 u
2 u = 30
1 u = 30 ÷ 2 = 15
Number of years' time so Caden will be 3 times as old as Lee
= 15 - 8
= 7 years
Answer(s): (a) (6
s - 10) years; (b) 7 years
