Answer with Solution:
1. (A); Number of male employees in unit C for company X
= 14% of 2500 × (3/7) = 150
Number of female employees in unit C for company Y
= 15% of 3000 × (1/3) = 150
2. (E); Number of female employees of company Y in unit E
= 22% of 3000 × 1/3 = 220
Number of male employees of company X in unit E
= 10% of 2500 × 2/5 = 100
:. Required more % = (220-100)/100 × 100
= 120%
3. (B); Number of male employees in different units for company Y : A = 300,
B = 240, C = 300, D = 100, E = 440 and F = 150.
Hence, our answer is A and C.
4. (C); Required ratio = (10%of 2500×2/5) / (15% of 3000×1/3)= 2 : 3
5. (A); Number of female employees for company Y in different units:
A = 60, B = 300, C = 150, D = 500, E = 220 and F = 240
6. (C); Average population (in thousands) of both the towns in 1994
= (45+44+48+45)/2
= 45 + 22 + 24 = 91 and that in 1998
= (50+47+50+47)/ 2
= 50 + 47 = 97
:. Required percentage increase = (6/91) × 100
= 6.59% Approx. 7%.
7. (B); Required ratio
8. (A); Population of X and Y in 1996
= (50 + 47+47 + 48 ) × 1000 = 192000
Population of X and Y in 1994
= (45 + 44 + 48 + 45) × 1000 = 182000
Now, 192 × 1000 = x × 182 × 1000
:. x = (192/182) = 1.05
9. (B); Average number of females for
X =1/5 (45 + 47 + 48 + 50 + 47) × 1000
= 237 × 200 = 47400
Y =1/5 (48 + 49 + 47 + 50 + 50) × 1000
= 244 × 200 = 48800
So, 1994, 1995 and 1998 are the three desired years for X and 1994 and 1996
are the two desired years for Y. Hence the required number of years is four
(1994, 1995, 1996 and 1998).
10. (B)
In 1994 → (45000 – 44000) = 1000
In 1995 → (47000 - 44000) = 3000
In 1996 → (48000 – 47000) = 1000
In 1997 → (50000 – 48000) = 2000
In 1998 → (47000 – 47000) = 0
The following pie-charts show the percentage of employees in two companies X and Y who are working in different units. Total numbers of employees in X and Y are 2500 and 3000 respectively.

Answer with Solution:
1. (A); Number of male employees in unit C for company X
= 14% of 2500 × (3/7) = 150
Number of female employees in unit C for company Y
= 15% of 3000 × (1/3) = 150
2. (E); Number of female employees of company Y in unit E
= 22% of 3000 × 1/3 = 220
Number of male employees of company X in unit E
= 10% of 2500 × 2/5 = 100
:. Required more % = (220-100)/100 × 100
= 120%
3. (B); Number of male employees in different units for company Y : A = 300,
B = 240, C = 300, D = 100, E = 440 and F = 150.
Hence, our answer is A and C.
4. (C); Required ratio = (10%of 2500×2/5) / (15% of 3000×1/3)= 2 : 3
5. (A); Number of female employees for company Y in different units:
A = 60, B = 300, C = 150, D = 500, E = 220 and F = 240
6. (C); Average population (in thousands) of both the towns in 1994
= (45+44+48+45)/2
= 45 + 22 + 24 = 91 and that in 1998
= (50+47+50+47)/ 2
= 50 + 47 = 97
:. Required percentage increase = (6/91) × 100
= 6.59% Approx. 7%.
7. (B); Required ratio
8. (A); Population of X and Y in 1996
= (50 + 47+47 + 48 ) × 1000 = 192000
Population of X and Y in 1994
= (45 + 44 + 48 + 45) × 1000 = 182000
Now, 192 × 1000 = x × 182 × 1000
:. x = (192/182) = 1.05
9. (B); Average number of females for
X =1/5 (45 + 47 + 48 + 50 + 47) × 1000
= 237 × 200 = 47400
Y =1/5 (48 + 49 + 47 + 50 + 50) × 1000
= 244 × 200 = 48800
So, 1994, 1995 and 1998 are the three desired years for X and 1994 and 1996
are the two desired years for Y. Hence the required number of years is four
(1994, 1995, 1996 and 1998).
10. (B)
In 1994 → (45000 – 44000) = 1000
In 1995 → (47000 - 44000) = 3000
In 1996 → (48000 – 47000) = 1000
In 1997 → (50000 – 48000) = 2000
In 1998 → (47000 – 47000) = 0

Answer
1. D); Total number of employees in Company A over all the years together
=(15+30+45+25+50+45)x 1000 =210000
Total number of employees in Company C in the year 2007 and 2008
= (50 +40) x 1000=90000
Reqd % = (210000x100/90000)=233.3% =Approx. 233%
2. C); Number of employees in Company B in the year 2008=35000
Number of employees in Company B in the year 2007=40000
%decrease = (40 -35)/40 x (1000/1000) x 100=12.5%
3. B); Number of employees in Company B in the year 2005=20000
Number of employees in Company C in the year 2007=50000
:. Reqd ratio =20000 : 50000 =2 : 5
4. D); Total number of employees in 2006 in all the companies together
=(30 +15 +25)x1000=70000
Number of female employees = 70000 x (30/100) = 21000
:. Number of male employees = (70000 - 21000)
=49000
5. A); Total number of employees in Company A, B and C in 2007
=(45 + 40 + 50) x 1000 =135000
Total number of employees in Company A, B and C in 2009 = (50 + 40 + 30) x 1000
=120000
Reqd ratio = 135000 :120000 =9 : 8
6. b
As per bar chart, Difference will be
[80-65]*100000 = 15,00,000 tonnes
Please note: we multiplied it by 100000, because graph is given in "lakh" tones
7. d
Average production of Company A in the period 2002 – 2005 = ( 55+ 60+ 65+ 50)/4= 57.5
Average production of Company C in the period 2002 – 2005 = (45+ 55+ 75+ 70)/4 =61.25
Required ratio = 61.25 : 57.5 = 2.45 : 2.30 = 49: 46
8. a
Percentage increase in the production of Company C from 2003 to 2005 = ((70-55) / 55) * 100
=(15/55) *100 = 27.27 % ≈ 27%
9. c
Average production of Company A in the period 2001 – 2005 = (70+ 55+ 60+ 65+ 50)/5= 60
Average production of Company B in the period 2001 – 2005 = (55+ 65+ 80+45+ 65)/5= 62
Average production of Company C in the period 2001 – 2005 = (60+45+ 55+ 75+ 70)/5 =61
So company B has the maximum average.
10. e
2001 → % = (55 /70)*100= 78.5 %
2002 → % = (65 / 55)*100= 118.2 %
2003→ % = (80/60)*100= 133.3%
2004→ % = (45/65)*100 = 69.2%
2005→ % = (65/50)*100= 130%

=120000
Reqd ratio = 135000 :120000 =9 : 8
6. b
As per bar chart, Difference will be
[80-65]*100000 = 15,00,000 tonnes
Please note: we multiplied it by 100000, because graph is given in "lakh" tones
7. d

Average production of Company C in the period 2002 – 2005 = (45+ 55+ 75+ 70)/4 =61.25
Required ratio = 61.25 : 57.5 = 2.45 : 2.30 = 49: 46
8. a
Percentage increase in the production of Company C from 2003 to 2005 = ((70-55) / 55) * 100
=(15/55) *100 = 27.27 % ≈ 27%
