Answer:
14.29%
Step-by-step explanation:
Calculation for the price-weighted index return
Price-weighted index return = [($25 + $12 + $35)/3] - [($20 + $15 + $28)/3]/[($20 + $15+ $28)/3]
Price-weighted index return =[($72/3)-($63/3)]/($63/3)
Price-weighted index return =($24-$21)/$21
Price-weighted index return =$3/$21
Price-weighted index return =0.1429*100
Price-weighted index return =14.29%
Therefore the Price-weighted index return will be 14.29%
