$1820 |
Amount that Michael received every month
= 1820 - 1400
= $420
1 u = 420
Amount that George received every month
= 3 u
= 3 x 420
= $1260
Amount that George had at first
= 1820 - 1260
= $560
Total amount that George and Michael had at first
= 1400 + 560
= $1960
George's amount : Total amount
560 : 1960
2 : 7
Answer(s): 2 : 7
