15 Oliver's savings : Total savings = 1 : 5
Ahmad's savings = 15 u
15 u = 165
1 u = 165 ÷ 15 = 11
Oliver's savings = 14 u
Savings of the other three boys
= 15 u + 27 u + 14 u
= 56 u
Savings that Oliver had less than the total of the three other boys
= 56 u - 14 u
= 42 u
= 42 x 11
= $462
Answer(s): $462
