Usha, Irene and Ivory bought a gift for their nephew. They shared the cost equally between them. Usha used ⁴₉ of her savings, Irene used ²₅ of her savings and Ivory used ⁵₆ of her savings. Usha and Ivory had $58 left. How much did each girl pay for the gift?
The amount spent by each girl is the same.  Make the numerators the same.
LCM of 4, 2 and 5 = 20

4x59x5 of Usha's savings = 2x105x10 of Irene's savings = 5x46x4 of Ivory savings
2045 of Usha's savings = 2050 of Irene's savings = 2024 of Ivory's savings

	Usha	Irene	Ivory
Before	45 u	50 u	24 u
Change	- 20 u	- 20 u	- 20 u
After	25 u	30 u	4 u

Savings that Usha had left
= 45 u - 20 u
= 25 u

Savings that Ivory had left
= 24 u - 20 u
= 4 u

Total savings that Usha and Ivory had left
= 25 u + 4 u
= 29 u

29 u = 58

1 u = 58 ÷ 29 = 2

Amount that each girl paid
= 20 u
= 20 x 2
= $40

Answer(s): $40
