Oliver and Paul had some money at first. Oliver received 2 times as much money as Paul every day. At the end of 6 days, both of them had the same amount of money.

$2100 |
Amount that Paul received every day
= 2100 - 1350
= $750
1 u = 750
Amount that Oliver received every day
= 2 u
= 2 x 750
= $1500
Amount that Oliver had at first
= 2100 - 1500
= $600
Total amount that Oliver and Paul had at first
= 1350 + 600
= $1950
Oliver's amount : Total amount
600 : 1950
4 : 13
Answer(s): 4 : 13
