110 Vaidev's savings : Total savings = 1 : 10
Michael's savings = 10 u
10 u = 330
1 u = 330 ÷ 10 = 33
Vaidev's savings = 3 u
Savings of the other three boys
= 10 u + 14 u + 3 u
= 27 u
Savings that Vaidev had less than the total of the three other boys
= 27 u - 3 u
= 24 u
= 24 x 33
= $792
Answer(s): $792
