310 Japheth's savings : Total savings = 3 : 10
Warren's savings = 25 u
25 u = 775
1 u = 775 ÷ 25 = 31
Zeph's savings = 16 u
Savings of the other three boys
= 25 u + 15 u + 24 u
= 64 u
Savings that Zeph had less than the total of the three other boys
= 64 u - 16 u
= 48 u
= 48 x 31
= $1488
Answer(s): $1488
