Tim and Xavier had some money at first. Tim received 2 times as much money as Xavier every week. At the end of 2 weeks, both of them had the same amount of money.

$1920 |
Amount that Xavier received every week
= 1920 - 1200
= $720
1 u = 720
Amount that Tim received every week
= 2 u
= 2 x 720
= $1440
Amount that Tim had at first
= 1920 - 1440
= $480
Total amount that Tim and Xavier had at first
= 1200 + 480
= $1680
Tim's amount : Total amount
480 : 1680
2 : 7
Answer(s): 2 : 7
