$2150 |
Amount that Bobby received every month
= 2150 - 1500
= $650
1 u = 650
Amount that Oscar received every month
= 3 u
= 3 x 650
= $1950
Amount that Oscar had at first
= 2150 - 1950
= $200
Total amount that Oscar and Bobby had at first
= 1500 + 200
= $1700
Oscar's amount : Total amount
200 : 1700
2 : 17
Answer(s): 2 : 17
