310 Perry's savings : Total savings = 3 : 10
Vaidev's savings = 10 u
10 u = 350
1 u = 350 ÷ 10 = 35
Perry's savings = 21 u
Savings of the other three boys
= 10 u + 25 u + 14 u
= 49 u
Savings that Perry had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 35
= $980
Answer(s): $980
