## Introduction to Data Interpretation

#### Data Interpretation

Direction: The table given here shows production of five types of cars by a company in the year 1989 to 1994. Study the table and answer questions. 1. In which year the production of cars of all types taken together was approximately equal to the average of the total production during the period?

1. According to given table, we have
Total production of cars of all types taken together in given years = 476
Number of given years = 6

 Average = Total production of cars of all types taken together in given years Number of given years

##### Correct Option: C

According to given table, we have
Total production of cars of all types taken together in given years = 476
Number of given years = 6

 Average = Total production of cars of all types taken together in given years Number of given years

 Average = 476 = 79.33 ≈ 80 6

Which is equal to total production of all types of cars in 1993.

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. 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

##### 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

1. The highest number of film- watchers in any given city is :

1. As per the given above table , we can see
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 , 100% ≈ 100 × 24000 = 60000 40

Similarly for city Q,
 ⇒ 100% ≈ 100 × 30000 = 37500 80

##### Correct Option: D

As per the given above table , we can see
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 , 100% ≈ 100 × 24000 = 60000 40

Similarly for city Q,
 ⇒ 100% ≈ 100 × 30000 = 37500 80

For city R,
 ⇒ 100% ≈ 100 × 24000 = 160000 15

For city S,
 ⇒ 100% ≈ 100 × 27000 = 60000 45

For city T,
 ⇒ 100% ≈ 100 × 80000 = 320000 25

Hence , highest number of film- watchers is for city T .

1. A city with the lowest number of film-watchers is :

1. 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 , 100% ≈ 100 × 24000 = 60000 40

Similarly for city Q,
 ⇒ 100% ≈ 100 × 30000 = 37500 80

##### Correct Option: B

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 , 100% ≈ 100 × 24000 = 60000 40

Similarly for city Q,
 ⇒ 100% ≈ 100 × 30000 = 37500 80

For city R,
 ⇒ 100% ≈ 100 × 24000 = 160000 15

For city S,
 ⇒ 100% ≈ 100 × 27000 = 60000 45

For city T,
 ⇒ 100% ≈ 100 × 80000 = 320000 25

Hence , the lowest number is for city Q .

1. Which city has the highest number of film watchers who see only one film in a week?
