## Introduction to Data Interpretation

#### Data Interpretation

Direction: A health drink company prepares the drink of three different flavours P, Q, R. The production of three flavours over a period of six years has been expressed on bar graph provided below. Study the graph and answer the questions.

1. In which of the following years the percentage of rise or fall in production from the previous year is maximum for the flavour of Q?

1. From the given bar diagram , we see
Production of flavour Q in 2007 = 50 lakh
Production of flavour Q in 2006 = 60 lakh
Decrease = Production of flavour Q in 2006 - Production of flavour Q in 2007 = 60 - 50 = 10

 In year 2007 , Decrease % = Decrease × 100 Production of flavour Q in 2006

##### Correct Option: A

From the given bar diagram , we see
Production of flavour Q in 2007 = 50 lakh
Production of flavour Q in 2006 = 60 lakh
Decrease = Production of flavour Q in 2006 - Production of flavour Q in 2007 = 60 - 50 = 10

 In year 2007 , Decrease % = Decrease × 100 Production of flavour Q in 2006

 In year 2007 , Decrease % = 10 × 100 = 16 2 % 60 3

Direction: Bar-chart showing the Sales of Books (in 1000) from six-branches B1 B2 , B3 , B4 , B5 and B6 of a Publishing Company in 2000 and 2001 is given below. Study the chart and answer the questions.

1. What is the average sale of books from all the branches for the year 2000?

1. According to given bar graph , we have
Total sale of books from all the branches for the year 2000 = 80 + 75 + 95 + 85 + 75 + 70 = 480
Number of branches = 6

 Required average = Total sale of books from all the branches for the year 2000 Number of branches

##### Correct Option: B

According to given bar graph , we have
Total sale of books from all the branches for the year 2000 = 80 + 75 + 95 + 85 + 75 + 70 = 480
Number of branches = 6

 Required average = Total sale of books from all the branches for the year 2000 Number of branches

 Required average = 480 = 80 6

1. What percent of the average sales of branches B1 , B2 and B3 in 2001 is the average sales of branches B1 , B3 and B6 in 2000?

1. As per the given bar graph , we have
Total sales of branches B1 , B2 and B3 in 2001 = 105 + 65 + 110 = 280
Number of branches = 3

 Average sales of stores B1 , B2 and B3 in 2001 = Total sales of branches B1 , B2 and B3 = 280 Number of branches 3

Total sales of branches B1 , B3 and B6 in 2000 = 80 + 95 + 70 = 245
Number of branches = 3
 Average sales of stores B1 , B3 and B6 in 2000 = Total sales of branches B1 , B3 and B6 = 245 Number of branches 3

##### Correct Option: A

As per the given bar graph , we have
Total sales of branches B1 , B2 and B3 in 2001 = 105 + 65 + 110 = 280
Number of branches = 3

 Average sales of stores B1 , B2 and B3 in 2001 = Total sales of branches B1 , B2 and B3 = 280 Number of branches 3

Total sales of branches B1 , B3 and B6 in 2000 = 80 + 95 + 70 = 245
Number of branches = 3
 Average sales of stores B1 , B3 and B6 in 2000 = Total sales of branches B1 , B3 and B6 = 245 Number of branches 3

 Required percentage = 245 × 100 = 87.5% 280

1. What is the ratio of the total sales of branch B2 for both the years to the total sales of branch B4 for both years?

1. From the given bar diagram , we see
Total sales of branch B2 for both the years = 75 + 65 = 140
Total sales of branch B4 for both the years = 85 + 95 = 180
Required ratio = Total sales of branch B2 for both the years : Total sales of branch B4 for both the years

##### Correct Option: D

From the given bar diagram , we see
Total sales of branch B2 for both the years = 75 + 65 = 140
Total sales of branch B4 for both the years = 85 + 95 = 180
Required ratio = Total sales of branch B2 for both the years : Total sales of branch B4 for both the years
∴ Required ratio = 140 : 180 = 7 : 9

1. Total sales of branch B6 for both the years is what percent of the total sales of branch B3 for both the years?

1. On the basis of given graph in question ,
Total sales of branch B6 for both the years = 70 + 80 = 150
Total sales of branch B3 for both the years = 110 + 95 = 205

 Required percentage = Total sales of branch B6 for both the years × 100 Total sales of branch B3 for both the years

##### Correct Option: B

On the basis of given graph in question ,
Total sales of branch B6 for both the years = 70 + 80 = 150
Total sales of branch B3 for both the years = 110 + 95 = 205

 Required percentage = Total sales of branch B6 for both the years × 100 Total sales of branch B3 for both the years

 Required percentage = 150 × 100 = 73.17% 205
