- Express Valen's age in terms of p.
- Elijah is 10 years old as of now. ln how many years' time will Valen be 4 times as old as Elijah?
(a)
Elijah's age =
p years
Pierre's age = 6
p years
Valen's age = (6
p - 11) years
(b)
p = 10
Difference in age remains unchanged.
Difference in age between Valen and Elijah
= (6
p - 11) -
p = 6
p -
p - 11
= 5
p - 11
= 5 x 10 - 11
= 39 years
Difference in the age when Valen will be 4 times as old as Elijah
= 4 u - 1 u
= 3 u
3 u = 39
1 u = 39 ÷ 3 = 13
Number of years' time so Valen will be 4 times as old as Elijah
