$2340 |
Amount that Bobby received every month
= 2340 - 1300
= $1040
1 u = 1040
Amount that Ken received every month
= 2 u
= 2 x 1040
= $2080
Amount that Ken had at first
= 2340 - 2080
= $260
Total amount that Ken and Bobby had at first
= 1300 + 260
= $1560
Ken's amount : Total amount
260 : 1560
1 : 6
Answer(s): 1 : 6
