The difference in the age between Mr Warren and his cousin at first and in the end remains the same.
Difference in the age between Mr Warren and his cousin
= 3 u - 1 u
= 2 u
2 u = 44 - 6
2 u = 38
1 u = 38 ÷ 2 = 19
Number of years' time so Mr Warren will be 3 times as old as his cousin
= 19 - 6
= 13
Answer(s): 13
