Sean and Japheth had some money at first. Sean received 2 times as much money as Japheth every month. At the end of 4 months, both of them had the same amount of money. If Japheth had $1400 at first and Sean had $1600 at the end of those 4 months, what is the ratio of Sean's money to the total amount of money at first?

+ 2 u |
+ 1 u |

$1600 |
$1600 |
Amount that Japheth received every month
= 1600 - 1400
= $200
1 u = 200
Amount that Sean received every month
= 2 u
= 2 x 200
= $400
Amount that Sean had at first
= 1600 - 400
= $1200
Total amount that Sean and Japheth had at first
= 1400 + 1200
= $2600
Sean's amount : Total amount
1200 : 2600
6 : 13
Answer(s): 6 : 13
