## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following table and answer the questions. 1. The total number of students scoring 50% or more marks is

1. According to given table, we have

##### Correct Option: D

According to given table, we have

1. Which school has the highest number of students scoring exactly 50% marks?

1. As per the given above table , we see
School B has the highest number of students scoring exactly 50% marks .

##### Correct Option: C

As per the given above table , we see
School B has the highest number of students scoring exactly 50% marks .
So , Option C is correct answer .

1. The ratio of the total number of students scoring marks less than 50% to that of scoring marks exactly 50% is

1. According to given table, we have
Total number of students scoring marks less than 50% = 240 + 220 + 300 + 280 + 210 = 1250
Total number of students scoring marks exactly 50% = 55 + 40 + 20 + 10 + 25 = 100

##### Correct Option: C

According to given table, we have
Total number of students scoring marks less than 50% = 240 + 220 + 300 + 280 + 210 = 1250
Total number of students scoring marks exactly 50% = 55 + 40 + 20 + 10 + 25 = 100
Required ratio = 1250 : 100 = 25 : 4

Direction: The following table gives zone wise survey report of the people of a country who take coffee. Study the table and answer the questions. 1. The ratio of the total number of people surveyed who take coffee more than 3 times a day to the total number of people who do not take coffee at all is

1. As per the given above table , we see
Number of people who take coffee more than 3 times a day = 410 + 310 + 700 + 1450 = 2870
Total number of people who do not take coffee at all = 950 + 430 + 620 + 50 = 2050
Required ratio = Number of people who take coffee more than 3 times a day : Total number of people who do not take coffee at all

##### Correct Option: B

As per the given above table , we see
Number of people who take coffee more than 3 times a day = 410 + 310 + 700 + 1450 = 2870
Total number of people who do not take coffee at all = 950 + 430 + 620 + 50 = 2050
Required ratio = Number of people who take coffee more than 3 times a day : Total number of people who do not take coffee at all
∴ Required ratio = 2870 : 2050 = 1.4 : 1 = 14 : 10 = 7 : 5

1. The percentage of people from non-west zone who take coffee ‘only once a week’ is approximately

1. On the basis of given table in question ,
Total people in north zone = 4840
Total people in south zone = 3390
Total people in east zone = 2820
Total population = 4840 + 3390 + 2820 = 11050
People who take coffee only once a week in these zones = 620 + 540 + 350 = 1510

##### Correct Option: D

On the basis of given table in question ,
Total people in north zone = 4840
Total people in south zone = 3390
Total people in east zone = 2820
Total population = 4840 + 3390 + 2820 = 11050
People who take coffee only once a week in these zones = 620 + 540 + 350 = 1510

 Required percent = 1510 × 100 ≈ 14 11050
