## Introduction to Data Interpretation

#### Data Interpretation

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 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

1. The subject for which growing of demand is minimum is

1. According to given bar graph , we have
Number of applicants for the year 2008 in botany = 265
And Number of applicants for the year 2009 in botany = 248

 Percentage increase = 265 - 248 × 100 248

##### Correct Option: C

According to given bar graph , we have
Number of applicants for the year 2008 in botany = 265
And Number of applicants for the year 2009 in botany = 248

 Percentage increase = 265 - 248 × 100 248

 Percentage increase = 1700 = 6.85% 248

1. The subject for which growing of demand is maximum is

1. From the given bar diagram , we see that percentage increase in Maths is maximum.

##### Correct Option: B

From the given bar diagram , we see that percentage increase in Maths is maximum.
Hence , required answer is Mathematics .

Direction: Study the graph carefully and answer the following questions. 1. What is the average production of the four states in the year 1994–95 taken together?

1. According to given bar graph , we have
Total production of the states in the year 1994–95 = 21 + 18 + 15 + 12 + 7 = 73 lakhs bales
Number of states = 5

 Required average production = Total production of the states in the year 1994–95 Number of states

##### Correct Option: B

According to given bar graph , we have
Total production of the states in the year 1994–95 = 21 + 18 + 15 + 12 + 7 = 73 lakhs bales
Number of states = 5

 Required average production = Total production of the states in the year 1994–95 Number of states

 Required average production = 73 = 14.6 lakh bales 5

1. How many states showing below-average production in 1992–93 showed above-average production in 1993–94?

1. As per the given bar graph , we have
Total production in 1992–93 = 6 + 12 + 5 + 9 + 8 = 40
Number of given states = 5

 Average production in 1992 – 93 = Total production in 1992–93 Number of given states

 Average production in 1992 – 93 = 40 = 8 lakh bales 5

Total production in 1993–94 = 14 + 18 + 9 + 9 + 14 = 64
Number of given states = 5

##### Correct Option: D

As per the given bar graph , we have
Total production in 1992–93 = 6 + 12 + 5 + 9 + 8 = 40
Number of given states = 5

 Average production in 1992 – 93 = Total production in 1992–93 Number of given states

 Average production in 1992 – 93 = 40 = 8 lakh bales 5

Total production in 1993–94 = 14 + 18 + 9 + 9 + 14 = 64
Number of given states = 5
 Average production in 1993-94 = Total production in 1993–94 Number of given states

 Average production in 1993-94 = 64 = 12.8 lakh bales 5
