Carl and Justin had some money at first. Carl received 3 times as much money as Justin every month. At the end of 2 months, both of them had the same amount of money. If Justin had $1380 at first and Carl had $2010 at the end of those 2 months, what is the ratio of Carl's money to the total amount of money at first?

$2010 |
Amount that Justin received every month
= 2010 - 1380
= $630
1 u = 630
Amount that Carl received every month
= 3 u
= 3 x 630
= $1890
Amount that Carl had at first
= 2010 - 1890
= $120
Total amount that Carl and Justin had at first
= 1380 + 120
= $1500
Carl's amount : Total amount
120 : 1500
2 : 25
Answer(s): 2 : 25
