Perry and Julian had some money at first. Perry received 2 times as much money as Julian every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If Julian had $1080 at first and Perry had $1890 at the end of those 2 fortnights, what is the ratio of Perry's money to the total amount of money at first?

$1890 |
Amount that Julian received every fortnight
= 1890 - 1080
= $810
1 u = 810
Amount that Perry received every fortnight
= 2 u
= 2 x 810
= $1620
Amount that Perry had at first
= 1890 - 1620
= $270
Total amount that Perry and Julian had at first
= 1080 + 270
= $1350
Perry's amount : Total amount
270 : 1350
1 : 5
Answer(s): 1 : 5
