310 Vaidev's savings : Total savings = 3 : 10
Sean's savings = 10 u
10 u = 180
1 u = 180 ÷ 10 = 18
Caden's savings = 21 u
Savings of the other three boys
= 10 u + 18 u + 21 u
= 49 u
Savings that Caden had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 18
= $504
Answer(s): $504
