(a)
Total age of Adam and Bryan now
= 50 - 32
= 18
Now
Adam's age = 5 u
Bryan's age = 1 u
Total age of Adam and Bryan = 6 u
6 u = 18
1 u = 18 ÷ 6 = 3
Bryan's age now
= 1 u
= 3
(b)
Number of years that Bryan is younger than Adam
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
(c)
Adam's age 14 years' ago
= 5 u - 14
= 5 x 3 - 14
= 15 - 14
= 1
Answer(s): (a) 3; (b) 12; (c) 1
