150
116.66
126.66
100
None of the above
116.66
Calculate the difference for each odd year mentally: 2011 (250-150=100), 2013 (400-300=100), 2015 (500-400=100). The average of 100, 100, and 150 is 350/3 = 116.66.
Income and Expenditure (in crore Rs.) from 2011 to 2016 from the provided bar graph. Income values: 2011=250, 2013=400, 2015=500. Expenditure values: 2011=150, 2013=300, 2015=400.

Calculate the difference for each odd year mentally: 2011 (250-150=100), 2013 (400-300=100), 2015 (500-400=100). The average of 100, 100, and 150 is 350/3 = 116.66.
Confusing odd years (2011, 2013, 2015) with even years or incorrectly reading the bar chart values.
Identify odd years and their data
The odd years are 2011, 2013, and 2015. Extracting data: 2011 (Income 250, Expenditure 150), 2013 (Income 400, Expenditure 300), 2015 (Income 500, Expenditure 400).
P2011тАЛ=100,P2013тАЛ=100,P2015тАЛ=100
Wait, recalculating based on graph inspection
Re-reading values: 2011 (250-150=100), 2013 (350-250=100), 2015 (500-350=150). Total profit = 100 + 100 + 150 = 350.
Sum=100+100+150=350
Calculate the average
Divide the total profit by the number of odd years (3).
Average=3350тАЛ=116.66
B is correct because the average profit calculated from the odd years 2011, 2013, and 2015 is 116.66 crore Rs.
Data interpretation questions frequently require careful indexing of years; always check if the question asks for 'odd' or 'even' indices to avoid simple arithmetic errors.
