Cody and Reggie had some money at first. Cody received 3 times as much money as Reggie every month. At the end of 2 months, both of them had the same amount of money. If Reggie had $1260 at first and Cody had $1820 at the end of those 2 months, what is the ratio of Cody's money to the total amount of money at first?

$1820 |
Amount that Reggie received every month
= 1820 - 1260
= $560
1 u = 560
Amount that Cody received every month
= 3 u
= 3 x 560
= $1680
Amount that Cody had at first
= 1820 - 1680
= $140
Total amount that Cody and Reggie had at first
= 1260 + 140
= $1400
Cody's amount : Total amount
140 : 1400
1 : 10
Answer(s): 1 : 10
