## Introduction to Data Interpretation

#### Data Interpretation

Direction: A survey of movie going habits of city dwellers from 5 cities A, B, C, D and E is given below. The first column gives the percentage of viewers in each city who watch less than two movies a week. The second column gives the total number of viewers who view two or more movies per week. Study the table and answer the questions.

1. The highest number of movie watchers in any given city (in the survey) is

1. According to given table,
Let total number of film watchers be 100% .
In city E, If 75% of them watched less than two movies a week , then 25% watched two or more movie per week .
∴ 25% ≡ 8000

 ⇒ 1% ≡ 8000 25

##### Correct Option: B

According to given table,
Let total number of film watchers be 100% .
In city E, If 75% of them watched less than two movies a week , then 25% watched two or more movie per week .
∴ 25% ≡ 8000

 ⇒ 1% ≡ 8000 25

 ∴ 100% ≡ 8000 × 100 = 32000 25

1. The city with the lowest number of movie watchers is

1. On the basis of given table in question ,
Let total number of film watchers be 100% .
In city A , If 60% of them watched less than two movies a week , then 40% watched two or more movie per week .
∴ 40% ≈ 2400

 ⇒ 1% = 2400 40

 Now , 100% = 100 × 2400 = 6000 40

Similarly for city B,
 ⇒ 100% = 100 × 3000 = 3750 80

##### Correct Option: C

On the basis of given table in question ,
Let total number of film watchers be 100% .
In city A , If 60% of them watched less than two movies a week , then 40% watched two or more movie per week .
∴ 40% ≈ 2400

 ⇒ 1% = 2400 40

 Now , 100% = 100 × 2400 = 6000 40

Similarly for city B,
 ⇒ 100% = 100 × 3000 = 3750 80

For city C,
 ⇒ 100% = 100 × 2400 = 16000 15

For city D,
 ⇒ 100% = 100 × 2700 = 6000 45

For city E,
 ⇒ 100% = 100 × 8000 = 32000 25

Hence , the lowest number is for city B .

1. How many viewers in city C watch less than two movies a week?

1. From the above given table , we have
Let total number of film watchers be 100% .
In city C , If 85% of them watched less than two movies a week , then 15% watched two or more movie per week .
⇒ 15% ≈ 2400

 ∴ 1% ≡ 2400 15

##### Correct Option: B

From the above given table , we have
Let total number of film watchers be 100% .
In city C , If 85% of them watched less than two movies a week , then 15% watched two or more movie per week .
⇒ 15% ≈ 2400

 ∴ 1% ≡ 2400 15

 ∴ 85% ≡ 2400 × 85 = 13600 15

Direction: The table given below depicts the export of a commodity through four ports in the years 1998 and 1999.

1. The percentage increase in the export of the commodity from the year 1998 to 1999 was the lowest from which port?

1. According to given table, we have
Export of Port C in 1998 = 229 crore rupees
Export of Port C in 1999 = 234 crore rupees
Increase = 234 - 229 = 5 crore rupees

 Percentage increase in Port C → 5 × 100 = 2.2% 229

Similarly , we can find percentage increase in other ports

##### Correct Option: C

According to given table, we have
Export of Port C in 1998 = 229 crore rupees
Export of Port C in 1999 = 234 crore rupees
Increase = 234 - 229 = 5 crore rupees

 Percentage increase in Port C → 5 × 100 = 2.2% 229

From above , the Percentage increase in the export of the commodity was the lowest from port C.

1. What was the average increase in the export of the commodity from the ports in the year 1999 as compared to the year 1998?

1. As per the given above table , we can see
Total increase in export = 4 + 12 + 5 + 4 = 25 crore rupees
Number of given ports = 4

 Average increase in export = \$ Total increase in export crore Number of given ports

##### Correct Option: D

As per the given above table , we can see
Total increase in export = 4 + 12 + 5 + 4 = 25 crore rupees
Number of given ports = 4

 Average increase in export = \$ Total increase in export crore Number of given ports

 Average increase in export = \$ 25 crore 4

 Average increase in export = \$ 25 ́ ×10000000 = \$ 62500000 4
