Archie and Warren had some money at first. Archie received 3 times as much money as Warren every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If Warren had $1440 at first and Archie had $2080 at the end of those 2 fortnights, what is the ratio of Archie's money to the total amount of money at first?

$2080 |
Amount that Warren received every fortnight
= 2080 - 1440
= $640
1 u = 640
Amount that Archie received every fortnight
= 3 u
= 3 x 640
= $1920
Amount that Archie had at first
= 2080 - 1920
= $160
Total amount that Archie and Warren had at first
= 1440 + 160
= $1600
Archie's amount : Total amount
160 : 1600
1 : 10
Answer(s): 1 : 10
