Warren and Tom had some money at first. Warren received 3 times as much money as Tom every month. At the end of 4 months, both of them had the same amount of money.

$1680 |
Amount that Tom received every month
= 1680 - 1140
= $540
1 u = 540
Amount that Warren received every month
= 3 u
= 3 x 540
= $1620
Amount that Warren had at first
= 1680 - 1620
= $60
Total amount that Warren and Tom had at first
= 1140 + 60
= $1200
Warren's amount : Total amount
60 : 1200
1 : 20
Answer(s): 1 : 20
