Explanation With Answer Key:
1).The graph shows that the price of Sports and Luxury watches decreases over the period.
Now, for Diamond watches the percentage increase from 2006 to 2012 is
= (200 – 150)/150 × 100
= 50/150 × 100
= 33 1/3 %
For Quartz watches the percentage increase from 2006 to 2012 is
= (300 – 50)/50 × 100
= 250/50 × 100
Answer is: d)
2).Average price of all watches in 2006
= 1/4 × (50 + 150 + 250 + 300) = 187.5
Average price of all watches in 2007
= 1/4 × (100 + 200 + 350 + 400) = 262.5
Average price of all watches in 2008
= 1/4 × (50 + 150 + 200 + 250) = 162.5
Average price of all watches in 2009
= 1/4 × (100 + 150 + 300 + 350) = 225
Average price of all watches in 2010
= 1/4 × (100 + 200 + 250 + 300) = 212.5
Average price of all watches in 2011
= 1/4 × (50 + 100 + 250 + 350) = 187.5
Average price of all watches in 2012
= 1/4 × (150 + 200 + 250 + 300) = 225
In 2008, the average price of all four types of watches is the minimum.
Answer is: e)
3).Total price of all four types of watches in 2012 is (150 + 200 + 250 + 300) = 900
Total price of all four types of watches in 2009 is (100 + 150 + 300 + 350) = 900
Both are equal, so the required percentage is 0%.
Answer is: c)
4).Required ratio
= Price of Diamond watches in 2008/Price of Quartz watches in 2009
Answer is: a)
5).Average price of Sports during 2006 to 2012
= 1/7 × (250 + 400 + 50 + 150 + 200 + 50 + 150) =
= 1250/7 = 178.57
Average price of Luxury during 2006 to 2012
= 1/7 × (300 + 350 + 250 + 350 + 300 + 350 + 250) =
Average price of Diamond during 2006 to 2012
= 1/7 × (150 + 100 + 200 + 300 + 100 + 250 +200) =
Average price of Quartz during 2006 to 2012
= 1/7 (50 + 200 + 150 + 100 t 250 + 100 + 300)
Thus, Luxury watches show the maximum average price during 2006 to 2012.
Answer is: b)
6).Number of staffs in Wipro
= 19 × 6400/100 = 1216
Number of female staffs in Wipro
= 1216 × 25/100
= 1216 × ¼
Number of male staffs in Wipro
= 1216 – 304 = 912
Answer is: d)
7).Number of staffs in Infosys
= 11 × 6400/100 = 704
Number of staffs in TCS
= 17 × 6400/100 = 1088
Number of staffs- in Wipro
= 19 × 6400/100 = 1216
Number of staffs in HCL
= 6 × 6400/100 = 384
Number of staffs in Oracle
= 29 × 6400/100 = 1856
Number of staffs in Mphasis
= 18 × 6400/100 = 1152
Difference = 3392 - 3008
Hence, HCL Company is equal to 384
Answer is: e)
8).Number of staffs in Mphasis
= 18 × 6400/100 = 1152
Number of directors in Mphasis
= 1152 × 1/36 = 32
Total salary of directors in Mphasis
= 32 × 96000 = 30.72 lakh
Answer is: a)
9).Average = (704+1216+384+1152)/4
Answer is: a)
10).Number of staffs in TCS
= 17 × 6400/100 = 1088
Number of staffs in HCL
= 6 × 6400/100 = 384
Number of staffs in Oracle
= 29 × 6400/100 = 1856
Required percentage = 1088/(1856 + 384) × 100
= 108800/2240
Answer is: c)
