Daniel is
h years old. Reggie is six times as old as Daniel and Wesley is 10 years younger than Reggie.
- Express Wesley's age in terms of h.
- Daniel is 10 years old as of now. ln how many years' time will Wesley be 3 times as old as Daniel?
(a)
Daniel's age =
h years
Reggie's age = 6
h years
Wesley's age = (6
h - 10) years
(b)
h = 10
Difference in age remains unchanged.
Difference in age between Wesley and Daniel
= (6
h - 10) -
h = 6
h -
h - 10
= 5
h - 10
= 5 x 10 - 10
= 40 years
Difference in the age when Wesley will be 3 times as old as Daniel
= 3 u - 1 u
= 2 u
2 u = 40
1 u = 40 ÷ 2 = 20
Number of years' time so Wesley will be 3 times as old as Daniel
= 20 - 10
= 10 years
