Seth and Luis had some money at first. Seth received 2 times as much money as Luis every fortnight. At the end of 4 fortnights, both of them had the same amount of money. If Luis had $1400 at first and Seth had $1700 at the end of those 4 fortnights, what is the ratio of Seth's money to the total amount of money at first?

$1700 |
Amount that Luis received every fortnight
= 1700 - 1400
= $300
1 u = 300
Amount that Seth received every fortnight
= 2 u
= 2 x 300
= $600
Amount that Seth had at first
= 1700 - 600
= $1100
Total amount that Seth and Luis had at first
= 1400 + 1100
= $2500
Seth's amount : Total amount
1100 : 2500
11 : 25
Answer(s): 11 : 25
