Sales (in crore) of the number of units of six different IT companies over the given years
 
Company Year
2012 2013 2014 2015 2016
Rolta India 110 90 140 210 175
Infosys 120 80 130 195 160
Wipro 180 70 129 185 195
TCS 190 65 118 165 185
Tech Mahindra 450 67 142 175 123
HCL 420 76 193 180 112
1
The number of units sold by company TCS in all the given years is what per cent of the number of units sold by Wipro from 2013 to 2016 ? (approx) 
» Explain it
D

TCS
 

=   190 + 65 + 118 + 165 + 185

=   723  


Wipro

=   70 + 129 + 185 + 195

=   579  


Required % = 723 × 100 ≈ 125 %
579


Hence, option D is correct.

2
The units sold by Rolta India in 2016 is what per cent less of the total number of units sold by all the companies together in that year ? (Find in approximation) 
» Explain it
C

Number of units sold by Rolta India in 2016 = 175


Total number of units sold in 2016 by all the companies

=   175 + 160 + 195 + 185 + 123 + 112

=   950


Therefore, required difference

=   950 - 175

=   775


Reqd. % =  775  × 100 = 81.57 ≈ 82%
950


Hence, option C is correct.

3
What is the approximate average number of units sold (in crore) in the year 2013 ?
» Explain it
A

Reqd. avg

=    90 + 80 + 70 + 65 +67 +76
6
=    448  
6

=   74.66 ≈ 75


Hence, option A is correct.


4
The ratio of units sold by Wipro In all the given years to the units sold by HCL in all the given years is?
» Explain it
C

Reqd ratio

=    180 + 70 + 129 + 185 + 195
420 + 76 + 193 + 180 + 112

=    759
981

=    253
327

=   253 : 327


Hence, option C is correct.

5
FInd the differnce between the average sales of 2014 and that of 2016 for all the companies taken together?
» Explain it
B

Total sales of 2014:

=   140 + 130 + 129 + 118 + 142 + 193

=    852


Total sales of 2016:

=   175 + 160 + 195 + 185 + 123 + 112

=   950


Difference in total sales

=   950 - 852

=   98


Reqd. average difference =  98  = 16.3
6


Hence, option B is correct.
