Answer:
Index value at the end of the day will be $70400.
Step-by-step explanation:
Simple index of this stock market will be calculated as
Index = Sum of (Number of shares × Share value) of all companies
= (5000×4.30 + 2000×3.20+ 8000×4.90)
= 67000 + 6400 + 39200 = $67100
Now This index rises 4.9% over the course of day then index will be
Index after growth = 67100 + 67100×4.9%
= 67100 + 67100×.049 = 67100 + 3287.9
= 70387.9
We have to give the answer in nearest hundred so the index value will be $70400.
