Direction: A survery of film watching habits of people living in five cities P, Q, R, S and T is summarized below in a table. The coulmn I in the table gives percentage of film-watchers in each city who see only one film a week. The column II gives the total number of film-watchers who see two or more films per week.

  1. The total number of all film-watchers in the five cities who see only one film in a week is
    1. 113000
    2. 425200
    3. 452500
    4. 500000
Correct Option: C

On the basis of given table in question ,
Let total number of film watchers be 100% .
In city P , If 60% of them watched only on movie in a week , then 40% watched two or more movie in a week .
⇒ 40% ≈ 24000

∴ 1% ≈
24000
40

Now , 60% ≈
60 × 24000
= 36000
40

Similarly for city Q,
⇒ 20% ≈
20 × 30000
= 7500
80

For city R,
⇒ 85% ≈
85 × 24000
= 136000
15

For city S,
⇒ 55% ≈
55 × 27000
= 33000
45

For city T,
⇒ 75% ≈
75 × 80000
= 240000
25

The total number of all film-watchers in the five cities = 36000 + 7500 + 136000 + 33000 + 240000 = 452500
