310 Japheth's savings : Total savings = 3 : 10
Paul's savings = 5 u
5 u = 180
1 u = 180 ÷ 5 = 36
Japheth's savings = 9 u
Savings of the other three boys
= 5 u + 7 u + 9 u
= 21 u
Savings that Japheth had less than the total of the three other boys
= 21 u - 9 u
= 12 u
= 12 x 36
= $432
Answer(s): $432
