Gabriel's age =
v years
Japheth's age = 5
v years
Oliver's age = (5
v - 4) years
(b)
v = 9
Difference in age remains unchanged.
Difference in age between Oliver and Gabriel

v - 4) -
v = 5
v -
v - 4
= 4
v - 4
= 4 x 9 - 4
= 32 years
Difference in the age when Oliver will be 3 times as old as Gabriel
= 3 u - 1 u
= 2 u
2 u = 32
1 u = 32 ÷ 2 = 16
Number of years' time so Oliver will be 3 times as old as Gabriel
