## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following line chart carefully and answer the questions given below it. The following line chart represents the number of employees recruited in different years in a company.

1. If the total number of employees before the year 2010 was 640, then the total number of employees after 2014 was :

1. As per the given line graph in question , we have
The total number of employees before the year 2010 = 640
The total number of employees after 2014 = 640 + total number of employees from 2010 to 2014

##### Correct Option: B

As per the given line graph in question , we have
The total number of employees before the year 2010 = 640
The total number of employees after 2014 = 640 + total number of employees from 2010 to 2014
Required answer = 640 + 35 + 45 + 25 + 50 + 40 = 835

1. The number of employees recruited in the year 2012 was what percent of the number employees recruited in the year 2014?

1. From the given graph in question ,
Number of employees recruited in 2012 = 25
Number of employees recruited in 2014 = 40

 ∴ Required percent = Number of employees recruited in 2012 × 100 Number of employees recruited in 2014

##### Correct Option: C

From the given graph in question ,
Number of employees recruited in 2012 = 25
Number of employees recruited in 2014 = 40

 ∴ Required percent = Number of employees recruited in 2012 × 100 Number of employees recruited in 2014

 ∴ Required percent = 25 × 100 = 62.5% 40

1. What was the ratio of number of employees recruited in the year 2011 to that in the year 2013?

1. On the basis of given graph in question ,
Number of employees recruited in the year 2011 = 45
Number of employees recruited in the year 2013 = 50
Required ratio = Number of employees recruited in the year 2011 : Number of employees recruited in the year 2013

##### Correct Option: B

On the basis of given graph in question ,
Number of employees recruited in the year 2011 = 45
Number of employees recruited in the year 2013 = 50
Required ratio = Number of employees recruited in the year 2011 : Number of employees recruited in the year 2013
∴ Required ratio = 45 : 50 = 9 : 10

Direction: Observe the graph below and answer the following question.

1. What is the average of diesel prices over the years 2006 – 2012?

1. According to given graph in question ,
Sum of diesel prices over the years 2006 – 2012 = 33.65 + 32.85 + 34.04 + 32.76 + 38.51 + 40.01 + 43.47
Total number of given years = 7

 Required average = \$ (33.65 + 32.85 + 34.04 + 32.76 + 38.51 + 40.01 + 43.47) 7

##### Correct Option: A

According to given graph in question ,
Sum of diesel prices over the years 2006 – 2012 = 33.65 + 32.85 + 34.04 + 32.76 + 38.51 + 40.01 + 43.47
Total number of given years = 7

 Required average = \$ (33.65 + 32.85 + 34.04 + 32.76 + 38.51 + 40.01 + 43.47) 7

 Required average = \$ 255.29 = \$ 36.47 7

1. In which year the difference between average prices of petrol and Diesel is minimum?

1. On the basis of given graph in question , we can see
Average prices of petrol in year 2014 = \$ 73.70
And Average prices of Diesel in year 2014 = \$ 66.79
Required Difference = Average prices of petrol in year 2014 - Average prices of Diesel in year 2014

##### Correct Option: C

On the basis of given graph in question , we can see
Average prices of petrol in year 2014 = \$ 73.70
And Average prices of Diesel in year 2014 = \$ 66.79
Required Difference = Average prices of petrol in year 2014 - Average prices of Diesel in year 2014
Required Difference = \$ (73.70 – 66.79) = \$ 6.91
It is obvious from the graph.
