The ratio of Vaidev's to Warren's money is 5 : 4. The ratio of Warren's to Asher's money is 3 : 5. If Vaidev has $255, how much less does Warren have than Asher?
| Vaidev |
Warren |
Asher |
| 5x3 |
4x3 |
|
| |
3x4 |
5x4 |
| 15 u |
12 u |
20 u |
The amount that Warren has is the repeated identity.
Use LCM to make it the same.
LCM of 4 and 3 = 12
Amount that Vaidev has = 15 u
15 u = 255
1 u = 255 ÷ 15 = 17
Amount that Warren has less than Asher
= 20 u - 12 u
= 8 u
= 8 x 17
= $136
Answer(s): $136
