Sam is
m years old. Wesley is five times as old as Sam and Bryan is 14 years younger than Wesley.
- Express Bryan's age in terms of m.
- Sam is 9 years old as of now. ln how many years' time will Bryan be 3 times as old as Sam?
(a)
Sam's age =
m years
Wesley's age = 5
m years
Bryan's age = (5
m - 14) years
(b)
m = 9
Difference in age remains unchanged.
Difference in age between Bryan and Sam
= (5
m - 14) -
m = 5
m -
m - 14
= 4
m - 14
= 4 x 9 - 14
= 22 years
Difference in the age when Bryan will be 3 times as old as Sam
= 3 u - 1 u
= 2 u
2 u = 22
1 u = 22 ÷ 2 = 11
Number of years' time so Bryan will be 3 times as old as Sam
= 11 - 9
= 2 years
