Solutions:
1. C) Total number of students = 6800
Total students who prefer beverage A and B together (in degree angles) = 79.2° + 57.6° = 136.8°
Total students who prefer beverage D and F together (in degree angles) = 122.4° + 21.6° = 144°
360° represents 6800
Required difference = [(144° - 136.8°)/(360°)] × 6800 = 136
2. A) Total number of students = 6800
Students who prefer beverage A (in degree angles) = 79.2°
Students who prefer beverage F (in degree angles) = 21.6°
Required ratio = [((21.6°)/(360°)) × 6800]/[((79.2°)/(360°)) × 6800] = (21.6°)/(79.2°) = 3 : 11
3. D) Total number of students = 6800
Total students who prefer beverage E and F together (in degree angles) = 64.8° + 21.6° = 86.4°
360° represents 6800
Required percentage = (86.4°)/(360°) × 100 = 24%
4. A) Total number of students = 6800
Students who prefer beverage B (in degree angles) = 57.6°
Students who prefer beverage D (in degree angles) = 122.4°
Required percentage = (57.6°)/(122.4°) × 100 = 47.05% 47%
5. A) Total number of students = 6800
Students who prefer beverage B (in degree angles) = 57.6°
Students who prefer beverage E (in degree angles) = 64.8°
Total students who prefer beverage B and E together (in degree angles) = 64.8° + 57.6° = 122.4°
Total number of students = (122.4°)/(360°) × 6800 = 2312
6. B) From the line and bar graphs we get,
Years
No. of Android
users (X)
Percentage of female
Android users (A)
No. of female Android users
= X × (A/100)
2005
45000
20
45000 × (20/100) = 9000
2006
50000
27
50000 × (27/100) = 13500
2007
40000
32
40000 × (32/100) = 12800
2008
60000
36
60000 × (36/100) = 21600
2009
72000
30
72000 × (30/100) = 21600
2010
76000
45
76000 × (45/100) = 34200
We can clearly observe that the no. of female Android mobile users are equal for the years 2008 and 2009.
7. C) From the line and bar graph,
The no. of Android mobile users in 2006 = 50000
Percentage of female Android mobile users in 2006 = 27
The no. of female Android mobile users in 2006 = 50000 × (27/100) = 13500
The no. of Windows mobile users in 2006 = 30000
Percentage of female Windows mobile users in 2006 = 12
The no. of female Windows mobile users in 2006 = 30000 × (12/100) = 3600
The required percentage = [(3600/13500) × 100]% = 26.66% ≈ 27%.
8. D) From the line and bar graph,
We can find the year in which the percentage of female Android and Windows mobile users is equal from the bar graph.
In 2008, the percentage of female Android and Windows mobile users is equal i.e. 36%.
The no. of Android mobile users in 2008 = 60000
Percentage of female Android mobile users in 2008 = 36
The no. of female Android mobile users in 2008 = 60000 × (36/100) = 21600
The no. of Windows mobile users in 2008 = 40000
Percentage of female Windows mobile users in 2008 = 36
The no. of female Windows mobile users in 2008 = 40000 × (36/100) = 14400
The difference between the no. of female Android and Windows mobile users in that year in which the percentage of female Android and Windows mobile users is equal = 21600 – 14400 = 7200.
9. A) From the line and bar graph,
The no. of Android mobile users in 2009 = 72000
Percentage of female Android mobile users in 2009 = 30
Percentage of male Android mobile users in 2009 = 100 – 30 = 70
The no. of male Android mobile users in 2009 = 72000 × (70/100) = 50400
The no. of Windows mobile users in 2009 = 32000
Percentage of female Windows mobile users in 2009 = 40
Percentage of male Windows mobile users in 2009 = 100 – 40 = 60
So, the no. of male Windows mobile users in 2009 = 32000 × (60/100) = 19200
The required ratio = 50400 : 19200 = 21 : 8.
10. B) From the line and bar graph,
Years
No. of Windows
users (X)
Percentage of female
Windows users (A)
No. of female Windows users
= X × (A/100)
2005
20000
8
20000 × (8/100) = 1600
2007
35000
25
35000 × (25/100) = 8750
2010
45000
30
45000 × (30/100) = 13500
The total no. of female Windows mobile users in 2005, 2007 and 2010
1600 + 8750 + 13500 = 23850
The average no. of female Windows mobile users in 2005, 2007 and 2010
23850/3 = 7950
11. B) Number of employee in department of HR in 2012 = 120
Number of employee in department of HR in 2013 = 150
Required % = 30/120 × 100 = 25%
12. D) The strength of employee in department of accounts in 2011, 2012, 2013, 2014 and 2015 was 220, 80, 250, 200 and 150, respectively.
So, the strength of employee in department of accounts was minimum at 2012.
13. A) Total strength of employees in 2011 = 200 + 250 + 220 + 300 = 970
Strength of employees in department of IT = 250
Then, required number of times = 970/250 = 3.88 ≈ 4
14. E) Number of employee in department of operation in 2015 = 60
Total number of employee = 100 + 80 + 150 + 60 = 390
Required % = 60/390 × 100 = 15.38%
15. C) Number of employee in department of HR in 2012 = 120
Total number of employees in that year = 120 + 250 + 80 + 140 = 590
Required % = 120/590 × 100 = 20.34%
