## Introduction to Data Interpretation

#### Data Interpretation

Direction: Sales of Books (in thousand numbers) from Six Branches – B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001. Study the graph and answer the questions. 1. The average sale of branches B1, B3 and B6 in 2000 is what percent of the average sale of branches B1, B2 and B3 in 2000?

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

 Average sale of branches B1, B2 and B3 in 2001 = 105 +65 + 110 3

 Average sale of branches B1, B2 and B3 in 2001 = 280 thousand 3

Total sale of branches B1, B3 and B6 in 2000 = 80 + 95 + 70 = 245 thousands
Number of given branches = 3
 Average sale of branches B1, B3 and B6 in 2000 = 80 + 95 + 70 Thousand 3

 Average sale of branches B1, B3 and B6 in 2000 = 245 Thousand 3

##### Correct Option: A

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

 Average sale of branches B1, B2 and B3 in 2001 = 105 +65 + 110 3

 Average sale of branches B1, B2 and B3 in 2001 = 280 thousand 3

Total sale of branches B1, B3 and B6 in 2000 = 80 + 95 + 70 = 245 thousands
Number of given branches = 3
 Average sale of branches B1, B3 and B6 in 2000 = 80 + 95 + 70 Thousand 3

 Average sale of branches B1, B3 and B6 in 2000 = 245 Thousand 3

 ∴ Required percentage = 81.66 × 100 93.33

 Required percentage = 24500 = 87.5% 280

1. Find the ratio of the total sales of branch B2 for both years to the total sales of branch B4 for both years.

1. According to given bar graph , we have
The total sales of branch B2 for both years = 75 + 65 = 140 thousands
The total sales of branch B4 for both years = 85 + 95 = 180 thousands
Required ratio = The total sales of branch B2 for both years : The total sales of branch B4 for both years

##### Correct Option: D

According to given bar graph , we have
The total sales of branch B2 for both years = 75 + 65 = 140 thousands
The total sales of branch B4 for both years = 85 + 95 = 180 thousands
Required ratio = The total sales of branch B2 for both years : The total sales of branch B4 for both years
Required ratio = 140 : 180 = 7 : 9

1. Total sale of branches B1, B3 and B5 together for both the years (in thousand) is

1. From the given bar diagram , we see
Total sale of branches B1, B3 and B5 together for both the years = (80 + 105 + 95 +110 + 75 + 95) thousands

##### Correct Option: D

From the given bar diagram , we see
Total sale of branches B1, B3 and B5 together for both the years = (80 + 105 + 95 +110 + 75 + 95) thousands = 560 thousands
Hence , required answer is option D.

Direction: The subject wise number of applicants for the year 2008 and 2009 in a college is given in the following chart. Study the graph and answer the questions. 1. The number of Mathematics seeking applicants increased by

1. On the basis of given graph in question ,
The number of Mathematics seeking applicants in 2009 = 2230
The number of Mathematics seeking applicants in 2008 = 1870

 Required percentage increase = (2230 - 1870) × 100 1870

##### Correct Option: C

On the basis of given graph in question ,
The number of Mathematics seeking applicants in 2009 = 2230
The number of Mathematics seeking applicants in 2008 = 1870

 Required percentage increase = (2230 - 1870) × 100 1870

 Required percentage increase = 36000 = 19.25% 1870

1. The number of Physics seeking applicants increased by

1. From the given bar diagram , we see
Number of Physics seeking applicants in 2009 = 1454
Number of Physics seeking applicants in 2008 = 1240

 Required percentage increase = (1454 - 1240) × 100 1240

##### Correct Option: A

From the given bar diagram , we see
Number of Physics seeking applicants in 2009 = 1454
Number of Physics seeking applicants in 2008 = 1240

 Required percentage increase = (1454 - 1240) × 100 1240

 Required percentage increase = 21400 = 17.26% 1240
