Emily, Lucy and Victoria had a sum of money. The amount of money Emily had was
34 of the amount of money Lucy had. The ratio of the amount of money Lucy had to the total amount of money Victoria and Lucy had was 2: 5. After Victoria gave $58 to Lucy, she had as much money as Lucy. How much more money did Victoria have than Emily in the end?
Emily |
Lucy |
Victoria |
3x1 = 3 u |
4x1 = 4 u |
|
|
2x2 = 4 u |
3x2 = 6 u |
3 u |
4 u |
6 u |
The amount that Lucy had is the repeated identity. Make the amount that Lucy had the same. LCM of 4 and 2 is 4.

+ 58 |
- 58 |
After |
3 u |
4 u + 58 |
6 u - 58 |
The amount that Victoria and Lucy had in the end is the same.
6 u - 58 = 4 u + 58
6 u - 4 u = 58 + 58
2 u = 116
1 u = 116 ÷ 2 = 58
Amount that Victoria had more than Emily in the end
= 6 u - 58 - 3 u
= 3 u - 58
= 3 x 58 - 58
= 174 - 58
= $116
Answer(s): $116
