Fabian and David had some money at first. Fabian received 3 times as much money as David every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If David had $1140 at first and Fabian had $1620 at the end of those 2 fortnights, what is the ratio of Fabian's money to the total amount of money at first?

$1620 |
Amount that David received every fortnight
= 1620 - 1140
= $480
1 u = 480
Amount that Fabian received every fortnight
= 3 u
= 3 x 480
= $1440
Amount that Fabian had at first
= 1620 - 1440
= $180
Total amount that Fabian and David had at first
= 1140 + 180
= $1320
Fabian's amount : Total amount
180 : 1320
3 : 22
Answer(s): 3 : 22
