310 Vaidev's savings : Total savings = 3 : 10
Andy's savings = 25 u
25 u = 350
1 u = 350 ÷ 25 = 14
Oscar's savings = 12 u
Savings of the other three boys
= 25 u + 5 u + 18 u
= 48 u
Savings that Oscar had less than the total of the three other boys
= 48 u - 12 u
= 36 u
= 36 x 14
= $504
Answer(s): $504
