310 Xavier's savings : Total savings = 3 : 10
Oscar's savings = 25 u
25 u = 950
1 u = 950 ÷ 25 = 38
Ben's savings = 16 u
Savings of the other three boys
= 25 u + 15 u + 24 u
= 64 u
Savings that Ben had less than the total of the three other boys
= 64 u - 16 u
= 48 u
= 48 x 38
= $1824
Answer(s): $1824
