Perry and Valen had some money at first. Perry received 2 times as much money as Valen every day. At the end of 4 days, both of them had the same amount of money. If Valen had $1120 at first and Perry had $2100 at the end of those 4 days, what is the ratio of Perry's money to the total amount of money at first?

$2100 |
Amount that Valen received every day
= 2100 - 1120
= $980
1 u = 980
Amount that Perry received every day
= 2 u
= 2 x 980
= $1960
Amount that Perry had at first
= 2100 - 1960
= $140
Total amount that Perry and Valen had at first
= 1120 + 140
= $1260
Perry's amount : Total amount
140 : 1260
1 : 9
Answer(s): 1 : 9
