45 of Owen's age. 28 years ago, the ratio of Michael's age to Owen's age was 5 : 8. How old is Owen now?

1x3 =
3 u |
The difference in the age between Michael and Owen at first and in the end remains unchanged. Make the difference in the age between Michael and Owen the same. LCM of 3 and 1 is 3.
Increase in Michael's age
= 12 u - 5 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Owen's age now
= 15 u
= 15 x 4
= 60
Answer(s): 60
