Bryan and Vincent had some money at first. Bryan received 3 times as much money as Vincent every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If Vincent had $1500 at first and Bryan had $1800 at the end of those 2 fortnights, what is the ratio of Bryan's money to the total amount of money at first?

$1800 |
Amount that Vincent received every fortnight
= 1800 - 1500
= $300
1 u = 300
Amount that Bryan received every fortnight
= 3 u
= 3 x 300
= $900
Amount that Bryan had at first
= 1800 - 900
= $900
Total amount that Bryan and Vincent had at first
= 1500 + 900
= $2400
Bryan's amount : Total amount
900 : 2400
3 : 8
Answer(s): 3 : 8
