Carl and Fred had some money at first. Carl received 2 times as much money as Fred every month. At the end of 4 months, both of them had the same amount of money. If Fred had $1400 at first and Carl had $1900 at the end of those 4 months, what is the ratio of Carl's money to the total amount of money at first?

$1900 |
Amount that Fred received every month
= 1900 - 1400
= $500
1 u = 500
Amount that Carl received every month
= 2 u
= 2 x 500
= $1000
Amount that Carl had at first
= 1900 - 1000
= $900
Total amount that Carl and Fred had at first
= 1400 + 900
= $2300
Carl's amount : Total amount
900 : 2300
9 : 23
Answer(s): 9 : 23
