Solutions Key:
(01-05):
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 % = (210000×100/90000)=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
(06-10):
6. D); The graph shows that the price of M and N type tiles decreases over the period
Now, for O type tiles the percentage increase from 2006 to 2012 is
(200 โ 150)/150 x 100 = 250/50 x 100 = 33 1/3 %
For P type tiles the percentage increase from 2006 to 2012 is
(300 โ 50)/50 x 100 = 250/50 x 100 = 500%
7. B); Average price of M during 2006 to 2012 = 1/7 (250 + 400 + 50 + 150 + 200 + 50 + 150) = 1250/7 = 178.57
Average price of N during 2006 to 2012 = 1/7 (300 + 350 + 250 + 350 + 300 + 350 + 250) = 2150/7 = 307.14
Average price of O during 2006 to 2012 = 1/7 (150 + 100 + 200 + 300 + 100 + 250 + 200) = 1300/7 = 185.714
Average price of P during 2006 to 2012 = 1/7 (50 + 200 + 150 + 100 + 250 + 100 + 300) = 164.28
Thus, N type of tiles show the maximum average price during 2006 to 2012
8. B); Average price of all tiles in
2006 => (50 + 150 + 250 + 300)/4 = 187.5
2007 => (100 + 200 + 350 + 400)/4 = 262.5
2008 => (50 + 150 + 200 + 250)/4 = 162.5
2009 => (100 + 150 + 300 + 350)/4 = 225
2010 => (100 + 200 + 250 + 300)/4 = 212.5
2011 => (50 + 100 + 250 + 350)/4 = 187.5
2012 => (150 + 200 + 250 + 300) = 225
Therefore in 2008, the average price of all four types is the minimum
9. C); Total price of all four types of tiles in 2012 = 150 + 200 + 250 + 300 = 900
Total price of all four types of tiles in 2009 = 100 + 150 + 300 + 350 = 900
Both are equal, so the required percentage is 0%
10. E); Required ratio = (Price of O type tile in 2008/ Price of O type tile in 2009)
=200 / 250 = 4/5
=4 : 5
