Refer to the data table below and answer the following question.
(Note: Figures given are in lakh rupees)

Company 2011 2012 2013 2014 2015
Company A 2000 2000 5000 2000 1000
Company B 2000 3000 1000 5000 2000
Company C 3000 2000 5000 3000 3000
For which of the following pairs of years are the total exports from the three Companies together equal?

Let's calculate the total exports for each year by summing the values for Companies A, B, and C:
Total Exports in 2011: 2000+2000+3000=7000

Total Exports in 2012: 2000+3000+2000=7000

Total Exports in 2013: 5000+1000+5000=11000

Total Exports in 2014: 2000+5000+3000=10000

Total Exports in 2015: 1000+2000+3000=6000

Comparing the total exports, the sum is equal for the pair of years 2011 & 2012 (both equal to 7000 lakh rupees).
