25 Owen's savings : Total savings = 2 : 5
Liam's savings = 20 u
20 u = 480
1 u = 480 ÷ 20 = 24
Oliver's savings = 11 u
Savings of the other three boys
= 20 u + 2 u + 22 u
= 44 u
Savings that Oliver had less than the total of the three other boys
= 44 u - 11 u
= 33 u
= 33 x 24
= $792
Answer(s): $792
