Answer:
index value = 855.15
Explanation:
given data
stocks priced = $29
stocks priced = $52
stocks priced = $62
shares = 380,000
shares = 465,000
shares = 613,000
change price = $29
change price = $49
change price = $65
solution
we know
share (x) price (y) change price (z) (x) (y) (x) (z)
380,000 $29 $29 11020000 11020000
465,000 $52 $49 24180000 22785000
613,000 $62 $65 38006000 39845000
total 73206000 73650000
so new index value is
index value = [tex]\frac{850*73650000}{73206000}[/tex]
index value = 855.15
