The table shows the production, imports and consumption of electricity of a particular State. Pick an appropriate bar graph that represents the statistics in the table.
 Year Electricity production Electricity imports Consumption 1985 70 70 65 1990 75 75 80 1995 80 70 70 2000 70 80 85

 a. Graph 1 b. Graph 2 c. Graph 3 d. Graph 4

#### Solution:

The height of the bars in green, tan and light turquoise colors indicate the units of electricity produced, imported and consumed in the corresponding year.

Observe the graphs to match the heights of the bars in each graph with the values given in the table.

It can be observed that the heights of bars in Graph 2 matches with the values given in the table.

So, Graph 2 shows appropriate representation of the data given in the table.

2.
The monthly sales of an automobile dealer are shown in the table. Pick an appropriate bar graph for the data.
 Months Sales in '000 $Jan 15 Feb 14 Mar 13 Apr 16 May 12 June 15  a. Figure 4 b. Figure 1 c. Figure 3 d. Figure 2 #### Solution: Plot the months on the x-axis at uniform intervals. The sales data needs to be plotted on y-axis. Select the correct scale so that the smallest as well as the largest value can be shown on the graph. Plot appropriate values for all the months as given in the table. The correct bar graph is shown by Figure 1. Correct answer : (2) 3. A survey conducted by the Education Department reveals the expenditures on the Secondary and the High schools. Pick an appropriate bar graph which represents the data shown in the table.  Year Elementary & Secondary school (in$millions) High school (in \$millions) 1985 325 225 1990 361 240 1995 418 274 2000 425 277

 a. Graph 1 b. Graph 2 c. Graph 3 d. Graph 4

#### Solution:

The height of each bar in the bar graph indicates the amount spent on the schools in the corresponding year.

Match the heights of each bar with the values given in the table.

Observe that the heights of the bars in Graph 1 match with the values given in the table.

So, Graph 1 represents the data in the table.

4.
The bar graph shows the opinion poll for all time favorite sports stars. Find the median for the bar graph.

 a. 19 b. 13 c. 15 d. 12

#### Solution:

The number of votes for each player is 23, 22, 20, 18, 14 and 13.

There are two middle data values in the data.

Median = average of two middle values = (20+18) / 2 = 19.

5.
The graph shows the number of vehicle registrations from the year 1995 to 2000. Calculate rise in percentage of the registrations from 1995 to 2000.

 a. 4.92 % b. 2.33 % c. 2.91 % d. 3.54%

#### Solution:

Number of vehicles registered in the year 2000 = 220 million

Number of vehicles registered in the year 1995 = 215 million

The percentage increase = (Increase in the number of vehicles/ original number of vehicles) x 100

So, percentage rise in vehicle registrations from 1995 to 2000 = (220Ã¢â‚¬â€œ215) / 215x 100 = (5 / 215) x 100 = 2.33%

6.
The table shows the number of students enrolled in the elementary, the secondary, and the high school. Choose the bar graph which represents the data in the table.

 Year Elementary school Middle school High school 1985 34 13 14 1990 36 14 13 1995 38 13 10 2000 37 15 15

 a. Graph 1 b. Graph 2 c. Graph 3 d. Graph 4

#### Solution:

The height of the bars in blue, gold and light green indicate the number of students enrolled in elementary, secondary and high school in the corresponding year.

Match the heights of the bars with the values given in the table.

It can be seen that the heights of the bars in Graph 1 match with the values given in the table.

So, Graph 1 is the bar graph that represents the data given in the table.

7.
The bar graph shows the average number of vacationers going to different holiday destinations per year. Which is the most popular holiday destination ?

 a. U.S East b. Asia c. Australia d. Canada

#### Solution:

The height of each bar in the graph indicates the average number of vacationers (in thousands) every year going to a particular holiday destination.

The place which has the maximum average number of vacationers per year will be the most popular holiday destination.

From the bar graph, the bar representing the average number of vacationers for Australia is the highest.
[An average of 40000 vacationers visit Australia every year.]

So, the most popular holiday destination is Australia.

8.
The number of chocolates that Nina ate last week are shown in the bar graph. On which day of the week did Nina eat two times as many chocolates as she did on Wednesday?

 a. Wednesday b. Tuesday c. Thursday d. Monday

#### Solution:

The number of chocolates Nina ate on Wednesday = 4

Two times the number of chocolates she ate on Wednesday = 2 x 4 = 8

Nina ate 8 chocolates on Monday.

9.
The list below tells you the number of toys withTanya, with different hair color.
6 toys with black hair, 2 toys with red hair, 4 toys with brown hair, and 4 toys with orange hair. Which of the following bar graphs represents this data?

 a. Graph 2 b. Graph 3 c. Graph 4 d. Graph 1

10.
The table shows the number of students admitted in a school from the year 1992 to 1996. Pick an appropriate bar graph to display the data.
 Year Number of students 1992 65 1993 85 1994 70 1995 55 1996 75

 a. Graph 4 b. Graph 3 c. Graph 1 d. Graph 2

#### Solution:

All the bar graphs have year on the horizontal axis and the number of students on the vertical axis.

Observe the heights of the bars in the graphs to match with the values given in the table

Only the graph 2 has the heights of the bars matched with the values in the table given.

So, Graph 2 is the appropriate graph.
