#### 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 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

1. Comparing the figures for USA vis-a-vis the developed nations, it can be concluded that.

1. According to given bar graph , we can say USA had better control on inflation.

##### Correct Option: A

According to given bar graph , we can say USA had better control on inflation.
Thus , option A is required answer for this question .

1. The change in rate of inflation was least in which of the following?

1. From the given bar diagram , we see
Inflation rate of world in 1987 = 16
Inflation rate of world in 1975 = 14.6
Change in world = Inflation rate of world in 1987 – Inflation rate of world in 1975

##### Correct Option: C

From the given bar diagram , we see
Inflation rate of world in 1987 = 16
Inflation rate of world in 1975 = 14.6
Change in world = Inflation rate of world in 1987 – Inflation rate of world in 1975
Change in world = 16 – 14.6 = 1.4
