Total amount = $520
Sharing Ratio = 2 : 4 : 7
[tex] \underline\green{Solution : } [/tex]
First Student Ratio : 2
Second Student Ratio : 4
Third Student Ratio : 7
Total Quantities of ratio = 2 + 4 + 7 = 13
Formula applied :
Share = Ratio of Student / Total quantities of ratio × Total amount
First Student share :
= 2/13 × 520
= $80
Second student share:
= 4/13 × 520
= $160
Third Student share :
= 7/13 × 520
= $280 .
Proof :
Total share = $520
( 80 + 160 + 280 )= $520
$520 = $520
