Perry and Vaidev had some money at first. Perry received 2 times as much money as Vaidev every month. At the end of 4 months, both of them had the same amount of money. If Vaidev had $1080 at first and Perry had $2120 at the end of those 4 months, what is the ratio of Perry's money to the total amount of money at first?

$2120 |
Amount that Vaidev received every month
= 2120 - 1080
= $1040
1 u = 1040
Amount that Perry received every month
= 2 u
= 2 x 1040
= $2080
Amount that Perry had at first
= 2120 - 2080
= $40
Total amount that Perry and Vaidev had at first
= 1080 + 40
= $1120
Perry's amount : Total amount
40 : 1120
1 : 28
Answer(s): 1 : 28
