Ian and Seth had some money at first. Ian received 5 times as much money as Seth every week. At the end of 6 weeks, both of them had the same amount of money.

$1740 |
Amount that Seth received every week
= 1740 - 1440
= $300
1 u = 300
Amount that Ian received every week
= 5 u
= 5 x 300
= $1500
Amount that Ian had at first
= 1740 - 1500
= $240
Total amount that Ian and Seth had at first
= 1440 + 240
= $1680
Ian's amount : Total amount
240 : 1680
1 : 7
Answer(s): 1 : 7
