10 u |
6x5 =
30 u |
40 u |
Change |
- 9 u |
- 5x5 =
- 25 u |
|
After |
1 u |
1x5 =
5 u |
|
Comparing Ivan
and John in the end |
1 u |
5 u |

The amount that John had in the end is the same. Make the amount that John had in the end the same. LCM of 1 and 5 is 5.
Total amount that John and Ivan had at first
= 10 u + 30 u
= 40 u
40 u = 920
1 u = 920 ÷ 40 = 23
Amount that John had at first
= 30 u
= 30 x 23
= $690
Answer(s): $690
