Ben and Harry had some money at first. Ben received 3 times as much money as Harry every week. At the end of 6 weeks, both of them had the same amount of money.

$1760 |
Amount that Harry received every week
= 1760 - 1430
= $330
1 u = 330
Amount that Ben received every week
= 3 u
= 3 x 330
= $990
Amount that Ben had at first
= 1760 - 990
= $770
Total amount that Ben and Harry had at first
= 1430 + 770
= $2200
Ben's amount : Total amount
770 : 2200
7 : 20
Answer(s): 7 : 20
