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

$1980 |
Amount that Oliver received every month
= 1980 - 1260
= $720
1 u = 720
Amount that Ryan received every month
= 2 u
= 2 x 720
= $1440
Amount that Ryan had at first
= 1980 - 1440
= $540
Total amount that Ryan and Oliver had at first
= 1260 + 540
= $1800
Ryan's amount : Total amount
540 : 1800
3 : 10
Answer(s): 3 : 10
