Eric and Seth had some money at first. Eric received 3 times as much money as Seth every month. At the end of 6 months, both of them had the same amount of money. If Seth had $1260 at first and Eric had $1860 at the end of those 6 months, what is the ratio of Eric's money to the total amount of money at first?

$1860 |
Amount that Seth received every month
= 1860 - 1260
= $600
1 u = 600
Amount that Eric received every month
= 3 u
= 3 x 600
= $1800
Amount that Eric had at first
= 1860 - 1800
= $60
Total amount that Eric and Seth had at first
= 1260 + 60
= $1320
Eric's amount : Total amount
60 : 1320
1 : 22
Answer(s): 1 : 22
