#### Data Interpretation

Direction: The Bar graphs represents the number of road accidents due to bus and car during the years 2008 2013. Study the graph and answer the questions. 1. The respective ratio between the accidents by cars in the year 2012, 2010 and 2008 is

1. On the basis of given graph in question ,
Number of accidents by cars in the year 2012 = 40 thousands
Number of accidents by cars in the year 2010 = 50 thousands
and Number of accidents by cars in the year 2008 = 40 thousands
Required ratio = Number of accidents by cars in the year 2012 : Number of accidents by cars in the year 2010 : Number of accidents by cars in the year 2008

##### Correct Option: B

On the basis of given graph in question ,
Number of accidents by cars in the year 2012 = 40 thousands
Number of accidents by cars in the year 2010 = 50 thousands
and Number of accidents by cars in the year 2008 = 40 thousands
Required ratio = Number of accidents by cars in the year 2012 : Number of accidents by cars in the year 2010 : Number of accidents by cars in the year 2008
Required ratio = 40 : 50 : 40 = 4 : 5 : 4

1. The respective ratio of the road accidents due to bus in the year 2008 to that by car in the year 2012 is

1. As per the given bar graph , we have
Number of the road accidents by bus in the year 2008 = 30 thousands
Number of the road accidents by car in the year 2012 = 40 thousands
Required ratio = Number of the road accidents by bus in the year 2008 : Number of the road accidents by car in the year 2012

##### Correct Option: D

As per the given bar graph , we have
Number of the road accidents by bus in the year 2008 = 30 thousands
Number of the road accidents by car in the year 2012 = 40 thousands
Required ratio = Number of the road accidents by bus in the year 2008 : Number of the road accidents by car in the year 2012
∴ Required ratio = 30 : 40 = 3 : 4

1. The total number of road accidents in the year 2009, 2011 and 2013 combined together is

1. According to given bar graph , we have
Total number of road accidents in the year 2009, 2011 and 2013 = (40 + 30 + 60 + 20 + 10 + 20) thousand

##### Correct Option: A

According to given bar graph , we have
Total number of road accidents in the year 2009, 2011 and 2013 = (40 + 30 + 60 + 20 + 10 + 20) thousand

Direction: Study the following Bar graph and answer the questions. The Bar Graph gives the annual rates of inflation in percentages for 1975 and 1987. 1. In the year 1987 , the inflation rate in the third world countries vis-a-vis the world jumped approximately by

1. On the basis of given graph in question ,
The inflation rate in the third world in 1987 = 36.2
The inflation rate in the third world in 1975 = 16
Increase = 36.2 - 16 = 20.2

 Percentage increase = Increase × 100 The inflation rate in the third world in 1975

##### Correct Option: B

On the basis of given graph in question ,
The inflation rate in the third world in 1987 = 36.2
The inflation rate in the third world in 1975 = 16
Increase = 36.2 - 16 = 20.2

 Percentage increase = Increase × 100 The inflation rate in the third world in 1975

 Percentage increase = 20.2 × 100 = 126.25 ≈ 126 16
