$1890 |
Amount that Glen received every month
= 1890 - 1350
= $540
1 u = 540
Amount that Sean received every month
= 3 u
= 3 x 540
= $1620
Amount that Sean had at first
= 1890 - 1620
= $270
Total amount that Sean and Glen had at first
= 1350 + 270
= $1620
Sean's amount : Total amount
270 : 1620
1 : 6
Answer(s): 1 : 6
