110 Gabriel's savings : Total savings = 1 : 10
Daniel's savings = 10 u
10 u = 400
1 u = 400 ÷ 10 = 40
Gabriel's savings = 3 u
Savings of the other three boys
= 10 u + 11 u + 6 u
= 27 u
Savings that Gabriel had less than the total of the three other boys
= 27 u - 3 u
= 24 u
= 24 x 40
= $960
Answer(s): $960
