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

$2160 |
Amount that Daniel received every month
= 2160 - 1440
= $720
1 u = 720
Amount that Seth received every month
= 2 u
= 2 x 720
= $1440
Amount that Seth had at first
= 2160 - 1440
= $720
Total amount that Seth and Daniel had at first
= 1440 + 720
= $2160
Seth's amount : Total amount
720 : 2160
1 : 3
Answer(s): 1 : 3
