3 u |
3x4 =
12 u |
15 u |
Change |
- 2 u |
- 2x4 =
- 8 u |
|
After |
1 u |
1x4 =
4 u |

Comparing Japheth
and Rael in the end |
1 u |
4 u |

The amount that Rael had in the end is the same. Make the amount that Rael had in the end the same. LCM of 1 and 4 is 4.
Total amount that Rael and Japheth had at first
= 3 u + 12 u
= 15 u
15 u = 180
1 u = 180 ÷ 15 = 12
Amount that Rael had at first
= 12 u
= 12 x 12
= $144
Answer(s): $144
