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

$2340 |
Amount that Paul received every month
= 2340 - 1320
= $1020
1 u = 1020
Amount that Justin received every month
= 2 u
= 2 x 1020
= $2040
Amount that Justin had at first
= 2340 - 2040
= $300
Total amount that Justin and Paul had at first
= 1320 + 300
= $1620
Justin's amount : Total amount
300 : 1620
5 : 27
Answer(s): 5 : 27
