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%
So for 2003 the percentage is highest.
