$1680 |
Amount that Tom received every month
= 1680 - 1320
= $360
1 u = 360
Amount that Michael received every month
= 4 u
= 4 x 360
= $1440
Amount that Michael had at first
= 1680 - 1440
= $240
Total amount that Michael and Tom had at first
= 1320 + 240
= $1560
Michael's amount : Total amount
240 : 1560
2 : 13
Answer(s): 2 : 13
