Fabian and Luis had some money at first. Fabian received 2 times as much money as Luis every month. At the end of 6 months, both of them had the same amount of money.

$1680 |
Amount that Luis received every month
= 1680 - 1440
= $240
1 u = 240
Amount that Fabian received every month
= 2 u
= 2 x 240
= $480
Amount that Fabian had at first
= 1680 - 480
= $1200
Total amount that Fabian and Luis had at first
= 1440 + 1200
= $2640
Fabian's amount : Total amount
1200 : 2640
5 : 11
Answer(s): 5 : 11
