Warren and Charlie had some money at first. Warren received 3 times as much money as Charlie every week. At the end of 4 weeks, both of them had the same amount of money. If Charlie had $1100 at first and Warren had $1600 at the end of those 4 weeks, what is the ratio of Warren's money to the total amount of money at first?

$1600 |
Amount that Charlie received every week
= 1600 - 1100
= $500
1 u = 500
Amount that Warren received every week
= 3 u
= 3 x 500
= $1500
Amount that Warren had at first
= 1600 - 1500
= $100
Total amount that Warren and Charlie had at first
= 1100 + 100
= $1200
Warren's amount : Total amount
100 : 1200
1 : 12
Answer(s): 1 : 12
