$1710 |
Amount that Ahmad received every month
= 1710 - 1350
= $360
1 u = 360
Amount that Justin received every month
= 2 u
= 2 x 360
= $720
Amount that Justin had at first
= 1710 - 720
= $990
Total amount that Justin and Ahmad had at first
= 1350 + 990
= $2340
Justin's amount : Total amount
990 : 2340
11 : 26
Answer(s): 11 : 26
