A survey of film-watching habits of people living in five cities A, B, C, D and E is summarised in a table given below. Column I in the table gives percentage of film watchers in each city who watch only one film a week while column II gives the total number of film - watchers who watch two or more films per week. Read the table and answer Questions.
How many cities have the number of film watchers above the average number of all film watchers in the cities above taken together ?
30% of people watch more than 1 movie in city A which is equal to 57,000 people
=> Total population in city A = $$\frac{57000}{30}\times100=1,90,000$$
Similarly, for other cities :
Average of film watchers in all cities (in '000) = $$\frac{190+50+250+288+181.8}{5}=\frac{959.8}{5}=191.96$$ = $$191960$$
$$\therefore$$ In 2 cities, C and D, the number of film watchers are above the average number of all film watchers in the cities above taken together.
=> Ans - (B)
