Bobby and Fabian had some money at first. Bobby received 2 times as much money as Fabian every month. At the end of 4 months, both of them had the same amount of money. If Fabian had $1400 at first and Bobby had $1700 at the end of those 4 months, what is the ratio of Bobby's money to the total amount of money at first?

$1700 |
$1700 |
Amount that Fabian received every month
= 1700 - 1400
= $300
1 u = 300
Amount that Bobby received every month
= 2 u
= 2 x 300
= $600
Amount that Bobby had at first
= 1700 - 600
= $1100
Total amount that Bobby and Fabian had at first
= 1400 + 1100
= $2500
Bobby's amount : Total amount
1100 : 2500
11 : 25
Answer(s): 11 : 25
