Ryan and Simon had some money at first. Ryan received 2 times as much money as Simon every month. At the end of 2 months, both of them had the same amount of money. If Simon had $1400 at first and Ryan had $1800 at the end of those 2 months, what is the ratio of Ryan's money to the total amount of money at first?

$1800 |
Amount that Simon received every month
= 1800 - 1400
= $400
1 u = 400
Amount that Ryan received every month
= 2 u
= 2 x 400
= $800
Amount that Ryan had at first
= 1800 - 800
= $1000
Total amount that Ryan and Simon had at first
= 1400 + 1000
= $2400
Ryan's amount : Total amount
1000 : 2400
5 : 12
Answer(s): 5 : 12
