## 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. 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

1. The number of Chemistry seeking applicants increased by

1. From the given bar diagram , we see
Number of Chemistry seeking applicants in 2009 = 2580
Number of Chemistry seeking applicants in 2008 = 2170

 Required percentage increase = (2580 - 2170) × 100 2170

##### Correct Option: B

From the given bar diagram , we see
Number of Chemistry seeking applicants in 2009 = 2580
Number of Chemistry seeking applicants in 2008 = 2170

 Required percentage increase = (2580 - 2170) × 100 2170

 Required percentage increase = 41000 = 18.89% 2170
