The ratio of Pierre's to Jenson's money is 3 : 8. The ratio of Jenson's to Vaidev's money is 3 : 4. If Pierre has $162, how much less does Jenson have than Vaidev?
| Pierre |
Jenson |
Vaidev |
| 3x3 |
8x3 |
|
| |
3x8 |
4x8 |
| 9 u |
24 u |
32 u |
The amount that Jenson has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Pierre has = 9 u
9 u = 162
1 u = 162 ÷ 9 = 18
Amount that Jenson has less than Vaidev
= 32 u - 24 u
= 8 u
= 8 x 18
= $144
Answer(s): $144
