Raeann, Emily and Usha had a sum of money. The amount of money Raeann had was
34 of the amount of money Emily had. The ratio of the amount of money Emily had to the total amount of money Usha and Emily had was 2: 5. After Usha gave $29 to Emily, she had as much money as Emily. How much more money did Usha have than Raeann in the end?
Raeann |
Emily |
Usha |
3x1 = 3 u |
4x1 = 4 u |
|
|
2x2 = 4 u |
3x2 = 6 u |
3 u |
4 u |
6 u |
The amount that Emily had is the repeated identity. Make the amount that Emily had the same. LCM of 4 and 2 is 4.

+ 29 |
- 29 |
After |
3 u |
4 u + 29 |
6 u - 29 |
The amount that Usha and Emily had in the end is the same.
6 u - 29 = 4 u + 29
6 u - 4 u = 29 + 29
2 u = 58
1 u = 58 ÷ 2 = 29
Amount that Usha had more than Raeann in the end
= 6 u - 29 - 3 u
= 3 u - 29
= 3 x 29 - 29
= 87 - 29
= $58
Answer(s): $58
