Usha, Winnie and Hazel had a sum of money. The amount of money Usha had was
34 of the amount of money Winnie had. The ratio of the amount of money Winnie had to the total amount of money Hazel and Winnie had was 2: 5. After Hazel gave $31 to Winnie, she had as much money as Winnie. How much more money did Hazel have than Usha in the end?
Usha |
Winnie |
Hazel |
3x1 = 3 u |
4x1 = 4 u |
|
|
2x2 = 4 u |
3x2 = 6 u |
3 u |
4 u |
6 u |
The amount that Winnie had is the repeated identity. Make the amount that Winnie had the same. LCM of 4 and 2 is 4.

+ 31 |
- 31 |
After |
3 u |
4 u + 31 |
6 u - 31 |
The amount that Hazel and Winnie had in the end is the same.
6 u - 31 = 4 u + 31
6 u - 4 u = 31 + 31
2 u = 62
1 u = 62 ÷ 2 = 31
Amount that Hazel had more than Usha in the end
= 6 u - 31 - 3 u
= 3 u - 31
= 3 x 31 - 31
= 93 - 31
= $62
Answer(s): $62
