## Bar graph

#### Data Interpretation

Direction: Study the bar diagram and answer questions based on it.

1. The number of persons killed in coal mines in 2006 was what percent of those killed in industrial accidents in that year?

1.  Required percentage = The number of persons killed in coal mines in 2006 X 100% The number of persons killed in industrial accidents in 2006

##### Correct Option: B

As per given graph , we can see that
The number of persons killed in coal mines in 2006 = 300
The number of persons killed in industrial accidents in 2006 = 1200

 ∴ Required percentage = The number of persons killed in coal mines in 2006 X 100% The number of persons killed in industrial accidents in 2006

 ∴ Required percentage = 300 X 100% = 25% 1200

Direction: Study the information given in each of these questions and then answer the questions.

1. What is the average female population in million?

1.  Average female population = sum of total numbers of females total number of cities

##### Correct Option: A

From above given table , we can see that
The total population of all cities = 12 + 15 + 17 + 19 + 22 = 85 million
Total males in all cities = 6.5 + 7.2 + 9.0 + 9.9 + 10.8 = 43.4 million
Total females = 85 – 43.4 = 41.6 million

 Average female population = sum of total numbers of females total number of cities

 = 41.6 = 8.32 million 5

1. The area of the circle is 616 cm2. What is the area of the rectangle?

1. ∵ Area of the circle = πr2
Required Area of the rectangle = Length x Breadth

##### Correct Option: C

given :- Area of the circle = 616
⇒ πr2 = 616
Put the value of π = 22/7 in above equation.
we will get,
⇒ r2 = 196
⇒ r = 14 cm
Length of the rectangle = Diameter of the circle = 2r
∴ Area of the rectangle = Length x Breadth
∴ Area of the rectangle = 28 × 14 = 392 cm2

Direction: Study the graph given below and answer the question asked there under.

1. What is the precentage of electrified villages in the state (A)?

1. Percentage of electrified villages in the state A = 100 - 25 .

##### Correct Option: D

Percentage of electrified villages in the state A = 100 - 25 = 75%

1. In which of the following states percentage of electrified villages is double the percentage of electrified villages in state (D)?

1. Percentage of electrified villages in state D = 100 - 60
Percentage of electrified villages in state C = 100 - 20

##### Correct Option: A

Percentage of electrified villages in state D = 100 - 60 = 40
Percentage of electrified villages in state C = 100 - 20 = 80
Hence, the percentage of electrified villages in the state C is double the percentage of electrified villages in state D.
