| Change |
- 2x3 =
- 6 u |
- 3x2 =
- 6 u |
- 1x6 =

| After |
5x3 =
15 u |
2x2 =
4 u |
3x6 =
18 u |

The amounts that Owen, Harry and Oscar spent is the same. Make the amounts that each boy spent the same. LCM of 2, 3 and 1 is 6.
Amounts that the 3 boys had at first
= 21 u + 10 u + 24 u
= 55 u
55 u = 165
1 u = 165 ÷ 55 = 3
Amount that Owen and Harry have in the end
= 15 u + 4 u
= 19 u
Amount that Owen and Harry have more than Oscar in the end
= 19 u - 18 u
= 1 u
= 1 x 3
= $3
Answer(s): $3
