6x3 =
18 u |
3x5 =
15 u |
$1221 |
| Change |
- 1x3 =
- 3 u |
- 2x5 =
- 10 u |
|
| After |
5x3 =
15 u |
1x5 =
5 u |
|
Comparing Reggie
and Vaidev in the end |
3x5 =
15 u |
1x5 =
5 u |
|
The amount that Reggie had in the end is repeated. Make the amount that Reggie had in the end the same. LCM of 5 and 3 is 15.
Total amount that Reggie and Vaidev had at first
= 18 u + 15 u
= 33 u
33 u = 1221
1 u = 1221 ÷ 33 = 37
Amount that Vaidev had at first
= 15 u
= 15 x 37
= $555
Answer(s): $555
