Comprehension:
Direction: The given bar graph shows the number of males and females in offices A,B, C, D and E.
The data about the total number of females of all five offices is represented by a pie chart. What is the central angle of the sector representing the number of females in office A?
Answer (Detailed Solution Below)
Bar Graph Question 1 Detailed Solution
⇒ Total number of females in all five office = 3000
⇒ 3000 represent = 360°
⇒ Number of females in office A = 500
⇒ 500 will represent = (360°/3000) × 500 = 60°
∴ The central angle is 60o.

⇒ Percentage of females in office D = (500/900) × 100 = 55.55%
∴ Required difference = 55.55% – 44.44% = 11.11%
⇒ Percentage of males in office E = (800/1700) × 100 = 47.05%
⇒ Percentage of females in office E = (900/1700) × 100 = 52.94%
∴ Required difference = 52.94% – 47.05% = 5.89%

Answer (Detailed Solution Below)
Bar Graph Question 6 Detailed Solution
Download Solution PDFCalculation:
Number of families having 1 member = 5
Total members = 5
Number of families having 2 members = 30
Total members = 60
Number of families having 3 members = 45
Total members = 135
Number of families having 4 members = 40
Total members = 160
Number of families having 5 members = 25
Total members = 125
Number of families having 6 members = 5
Total members = 30
So, the total membes in all types of families = 5 + 60 + 135 + 160 + 125 + 30 = 515
Total number of families = 5 + 30 + 45 + 40 + 25 + 5 =150
The average family size = 515 / 150 = 3.4
Hence, option 3 is correct.

Answer (Detailed Solution Below)
Bar Graph Question 8 Detailed Solution
Download Solution PDFCalculation:
Number of families having 1 member = 5
Total members = 5
Number of families having 2 member = 30
Total members = 60
Number of families having 3 member = 45
Total members = 135
Number of families having 4 member = 40
Total members = 160
Number of families having 5 member = 25
Total members = 125
Number of families having 6 member = 5
Total members = 30
So, the total members in all types of families = 5 + 60 + 135 + 160 + 125 + 30 = 515
Total number of families = 5 + 30 + 45 + 40 + 25 + 5 =150
The average family size = 515 / 150 = 3.4
The families with size less than the average family size are as follows:
Number of families having 1 member = 5
Number of families having 2 member = 30
Number of families having 3 member = 45
So, the total number of families with size less than the average family size = 80
The total number of families = 150
The fraction of families with size less than the average family size = 80 / 150 = 8 / 15
Hence, option 2 is correct.

Based on the bar graph given, calculate the approximate percentage increase in sales of mobile phones from 2004 to 2008.
Answer (Detailed Solution Below)
Bar Graph Question 10 Detailed Solution
Download Solution PDFCalculation:
Percentage increase in sales of mobile phones in 2004 = 35
Percentage increase in sales of mobile phones in 2008 = 70

⇒ 35/35 × 100
⇒ 100%
∴ The required percentage is 100%

The maximum rise in the production of raw wool with respect to previous year :
Answer (Detailed Solution Below)
Bar Graph Question 13 Detailed Solution
Download Solution PDFCalculation:
Rise in 2015-16 = 53 – 51 = 2
Rise in 2016-17 = 65 – 53 = 12
Rise in 2017-18 = 76 – 65 = 11
Rise in 2019-20 = 68 – 58 = 10
Rise in 2020-21 = 73 – 68 = 5
∴ Maximum rise in production of wool with respect to previous year is in 2016-17
The given histogram shows the heights of 232 students of an athletic club and their numbers.
Study the histogram carefully and answer the questions that follows.
If the histogram is to be presented by a line diagram, what would be the starting point and the end point of the line diagram?
Answer (Detailed Solution Below)
Bar Graph Question 14 Detailed Solution
Download Solution PDFGiven:-
Athletic club of 232 members and their height's frequency.
Concept used:-
Frequency Polygon:- A frequency polygon is a graph constructed by using lines to join the midpoints of each interval or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.
Formula Used:
Class size = Upper limit - Lower limit
Calculation:
From histogram -
Class size = Upper limit - Lower limit
Class size = 125 - 120 = 5
∴ Mid point of a class = 5/2 = 2.5
So, Starting point of Line graph -
X - co-ordinate = 120 - 2.5 = 117.5
Y - co-ordinate = frequency of point = 0
∴ Starting point = (117.5,0)
End point of Line graph -
X - co-ordinate = 170 + 2.5 = 172.5
Y - co-ordinate = frequency of point = 0
∴ End point = (172.5,0)
∴ Required points are (117.5,0) and (172.5,0).
The following bar graph shows the number of coolers sold by shopkeepers A and B in different years. Study the graph and answer the question that follows.
The total number of coolers sold by shopkeeper B in 1995 and 1998 together is approximately what percentage more/less than the total number of coolers sold by the shopkeeper A in 1996 and 1997 together ?
Answer (Detailed Solution Below)
Bar Graph Question 15 Detailed Solution
Download Solution PDFGiven:
B(1995 + 1998) = 1620 + 1600
A(1996 + 1997) = 1590 + 1750
Solution:
The total number of coolers sold by shopkeeper B in 1995 and 1998 = 1620 + 1600 = 3220
The total number of coolers sold by shopkeeper A in 1996 and 1997 = 1590 + 1750 = 3340
difference = 3220 - 3340 = -120
⇒ less
Required percentage = 120/3340 x 100 = 3.5% ~ 4% less
Hence, the correct option is 2.
