Step: 1

From the bar graph, compare the height of bar with the scale on the left.

Step: 2

The bar above 0-2 minutes is on 6 on the scale.

Step: 3

The bar above 2-4 minutes is on 3 on the scale.

Step: 4

The number of trucks that crossed the bridge in the first 4 minutes = number of trucks that crossed the bridge from 0-2 minutes + number of trucks that crossed the bridge from 2-4 minutes

Step: 5

= 6 + 3

[Substitute the values.]

Step: 6

= 9

[Add.]

Step: 7

The total number of trucks that crossed the bridge in the first 4 minutes is 9.

Correct Answer is : 9

Step: 1

The height of each bar in the histogram indicates the number of working women in the corresponding age group.

Step: 2

Number of working women in the age group of 26 - 28 years = number of women in the age group of 26 - 27 years + number of women in the age group of 27 - 28 years

Step: 3

From the histogram, the number of working women in the age group of 26 - 27 years = 90

[The height of the bar representing 26 - 27.]

Step: 4

The number of working women in the age group of 27 - 28 years = 100

[The height of the bar representing 27 - 28.]

Step: 5

Number of women in the age group of 26 - 28 years = 90 + 100 = 190

[Substitute and add.]

Step: 6

So, the number of working women in the age group of 26 - 28 years is 190.

Correct Answer is : 190

Step: 1

Step: 1

The height of each bar in the histogram indicates the number of directors who has completed respective number of movies in the year.

Step: 2

From the graph, the number of directors who made 2 to 4 movies in the year is 20.

Step: 3

The number of directors who made 6 to 8 movies in the year is 10.

Step: 4

The difference between the two numbers = 20 - 10 = 10

[Subtract 10 from 20.]

Step: 5

So, 10 more directors made 2 to 4 movies in the year than those who made 6 to 8 movies.

Correct Answer is : 10

Step: 1

From the graph, the number of employees retired from 1990-92 is 250.

Step: 2

From the graph, the number of employees retired from 1992-94 is 200.

Step: 3

From the graph, the number of employees retired from 1994-96 is 300.

Step: 4

From the graph, the number of employees retired from 1996-98 is 150.

Step: 5

So, the number of employees retired from 1990-98 = 250 + 200 + 300+ 150 = 900.

[Add.]

Correct Answer is : 900

Step: 1

Number of employees working in between 4 to 7 hours = Height of the rectangle corresponding to the class interval 4 - 7

[Height of each rectangle represent the frequency of each class.]

Step: 2

= 6

Step: 3

So, 6 employees work in between 4 to 7 hours..

Correct Answer is : 6

Step: 1

The height of each bar on the histogram tells us how many workers receive the corresponding wages in dollars.

Step: 2

Number of workers who receive more than Rs 70 = Number of workers whose wages is between Rs 70 - 75 + Number of workers whose wages is between Rs 75 - 80

Step: 3

= 3 + 1 = 4

Step: 4

Therefore, 4 workers receive more than Rs 70.

Correct Answer is : 4
