Ryan and Luke had some money at first. Ryan received 4 times as much money as Luke every day. At the end of 4 days, both of them had the same amount of money.

$1660 |
Amount that Luke received every day
= 1660 - 1320
= $340
1 u = 340
Amount that Ryan received every day
= 4 u
= 4 x 340
= $1360
Amount that Ryan had at first
= 1660 - 1360
= $300
Total amount that Ryan and Luke had at first
= 1320 + 300
= $1620
Ryan's amount : Total amount
300 : 1620
5 : 27
Answer(s): 5 : 27
