Rate of change for Bihar

Rate of change for Orissa

Rate of change for Haryana

Hence, Orissa shows the maximum rate of change.

There is a slight ambiguity in the question regarding the distribution of states across the eastern and southern telecom circle. So avoid finding the exact figures in the region. A simple observation is that the subscribers of Idea and Airtel in south bears the ration 48 : 52 = 0.92 Going by options, only option (D) exactly matches this rate Note: Though not advisable in exams, the figures car be calculated exactly if we consider Bihar, West Bengal, Orissa Kolkata and Assam in the eastern circle and Tamil Nadu, Karnataka, Andhra Pradesh and Kerala in southern circle.

There is again ambiguity regarding the distribution of states in the eastern circle. Moreover, no instruction has been given to use the data from previous question, without which the question is not likely to be answerable.

Considering the data from the above question holds true, we get the following solution:

R –com subscribers in the eastern circle was 28% of the total subscribers whereas it is the same 28% in UP and Madhya Pradesh.

∴ R-com subscribers in new eastern circle = 28%.

There was no Idea subscriber in eastern region whereas 32% in UP and Madhya Pradesh

∴ Idea subscribers in new eastern region = 32% of (UP + Madhya Pradesh)

Total subscribers in new eastern circle = 30.03 + 77.22 +111.05 = 218.3 million

∴ Percentage of Idea subscribers

∴ Remaining subscribers in new eastern circle using Vodafone

= 100% – 28% – 16.27% = 55.73%.
