Perry and Sean had some money at first. Perry received 2 times as much money as Sean every week. At the end of 6 weeks, both of them had the same amount of money.

$2160 |
Amount that Sean received every week
= 2160 - 1200
= $960
1 u = 960
Amount that Perry received every week
= 2 u
= 2 x 960
= $1920
Amount that Perry had at first
= 2160 - 1920
= $240
Total amount that Perry and Sean had at first
= 1200 + 240
= $1440
Perry's amount : Total amount
240 : 1440
1 : 6
Answer(s): 1 : 6
