The following graph shows the profit made by three companies, A, B and C, over 6 years. Answer the question given below based on the graph.

For which two years was the total profit made by the three companies the same?

Correct option is B

​Given:
Profit (in units) for companies A, B, and C over 6 years:

​Solution:​

2010: A = 30, B = 60, C = 80. Total = 170.

2011: A = 60, B = 90, C = 40. Total = 190.

2012: A = 40, B = 120, C = 60. Total = 220.

2013: A = 70, B = 90, C = 60. Total = 220.

2014: A = 50, B = 60, C = 70. Total = 180.

2015: A = 120, B = 80, C = 100. Total = 300.

The total profit is the same in 2012 and 2013.
