What is ratio between BSNL users from 2009 to 2014 and Vodafone users from 2008 to 2016?
» Explain it
B
Following the common explanation, we get

Total number of BSNL users from 2009 to 14 = 11500 + 12800 + 14600 + 16500 + 18000 + 20400 = 93800
 
And, the total number of Vodafone users from 2008 to 16 = 2200 + 2350 + 2400 + 2460 + 2530 + 2560 + 2640 + 2730 + 2850 = 22720
 
  Reqd ratio = 93800 : 22720 = 2345 : 568.

Hence, option B is correct.

The total number of Airtel and Reliance users in 2010 is what percentage more than the total number of BSNL and Idea users in 2012?
» Explain it
C
Following the common explanation, we get

Total number of Airtel and Reliance users in the year 2010 = 13500 + 16400 = 29900

Total number of BSNL and Idea users in 2012 = 16500 + 12500 = 29000

∴   Reqd % =  29900 – 29000  × 100 =  900  × 100 = 3.1%
29000 29000

Hence, option C is correct.

In 2009 the turnover of Airtel was Rs. 174 Crores. If the turnover of Airtel in 2014 was Rs. 189 Crores, what is the percentage increase in the average earnings per Airtel user from 2009 to 2014?
» Explain it
C
As per the common explanation, we get

Earning of Airtel from each user in 2009

 =  174 Crores  = 145000
12000

Similary, in year 2014 =  189 Crores  = 150000
12600

∴   Reqd % =  150000 – 145000  × 100 = 3.44%
145000

Hence, option C is correct.

If Reliance and Vodafone gives 50 mb and 30 mb free data respectively to lucrate their users in the year 2013 is approximate how much less than the Idea users, which also gives 50 mb free data to their users in the same year. (1024 mb = 1 GB) 
» Explain it
A
Following the common explanation, we get

Total amount of data Reliance gives to their users in 2013 = 20400 × 50 = 1020000 mb ≈ 996 GB
 
Similarly, Vodafone = 2560 × 30 = 76800 mb = 75 GB
 
Therefore, total data of Reliance and Vodafone  = 996 + 75 = 1071 GB 
 
And, Idea = 32800 × 50 = 1640000 mb ≈ 1602 GB 
 
  Reqd difference = 1602 – 1071 = 531 GB

Hence, option A is correct.

If 30% of users from all other networks of 2016 switched to Reliance network in 2017, approximate what percent Reliance users hike from 2016?
» Explain it
D
Following the common explanation, we get

The total number of users of all other networks = Total users of 2016 – Reliance users of 2016 = 96550 – 22400 = 74150

And, the total number of users chose Reliance network = 30% of 74150 = 22245

Total number of users of Reliance network in 2016 = 22400

∴   Total percentage increase =  22245  × 100 ≈ 99%
22400

Hence, option D is correct.
