Owen and Riordan had some money at first. Owen received 2 times as much money as Riordan every week. At the end of 2 weeks, both of them had the same amount of money. If Riordan had $1330 at first and Owen had $1710 at the end of those 2 weeks, what is the ratio of Owen's money to the total amount of money at first?

$1710 |
Amount that Riordan received every week
= 1710 - 1330
= $380
1 u = 380
Amount that Owen received every week
= 2 u
= 2 x 380
= $760
Amount that Owen had at first
= 1710 - 760
= $950
Total amount that Owen and Riordan had at first
= 1330 + 950
= $2280
Owen's amount : Total amount
950 : 2280
5 : 12
Answer(s): 5 : 12
