Carl and Michael had some money at first. Carl received 2 times as much money as Michael every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If Michael had $1200 at first and Carl had $2040 at the end of those 2 fortnights, what is the ratio of Carl's money to the total amount of money at first?

$2040 |
Amount that Michael received every fortnight
= 2040 - 1200
= $840
1 u = 840
Amount that Carl received every fortnight
= 2 u
= 2 x 840
= $1680
Amount that Carl had at first
= 2040 - 1680
= $360
Total amount that Carl and Michael had at first
= 1200 + 360
= $1560
Carl's amount : Total amount
360 : 1560
3 : 13
Answer(s): 3 : 13
