110 George's savings : Total savings = 1 : 10
Archie's savings = 14 u
14 u = 420
1 u = 420 ÷ 14 = 30
George's savings = 3 u
Savings of the other three boys
= 14 u + 1 u + 12 u
= 27 u
Savings that George had less than the total of the three other boys
= 27 u - 3 u
= 24 u
= 24 x 30
= $720
Answer(s): $720
