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

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

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

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

= 6 + 3

= 9

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

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

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

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

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

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

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

Each point on the graph indicates the profit the company made in the corresponding year.

From the line graph, we learn that the profit the company made in the year 2003 is $3 million.

From the histogram, The height of the bar during the period 2001-02 is maximum.

So, the exports quality is highest during the period 2001-02 .

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

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

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

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

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

Consider each choice listed. Interpret each choice and compare with the graph shown.

Among the choices, ′more students scored 60 - 80 than 80 - 100′ is a valid statement.

The height of a bar in the bar graph represents the number of candles of that particular color.

The bar representing the candles in pink color is the smallest than all the other bars.

So, the pink colored candles are lowest in number.

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

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

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

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

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

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

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

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

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

= 3 + 1 = 4

Therefore, 4 workers receive more than Rs 70.

The height of each bar on the histogram tells us the number of boxes in which the corresponding range of rotten apples were found.

The bar above the range 4-6 reaches 4 on the scale.

Therefore, 4 boxes had 4 - 6 rotten apples.
