Study the following graph to answer these questions.
The following bar graph shows the revenue generated by three realty firms A, B and C during 2012 to 2016. Each of these firms builds Low Income Group (LIG) apartments, Middle Income Group (MIG) apartments and High Income Group (HIG) apartments.
If the profit earned by A in 2015 is $$\dfrac{1}{6}th$$ of the average of the revenues of A in 2015, B in 2013 and C in 2012, the investment of A in 2015 is ..........
Solution
The revenue of A in 2015, B in 2013 and C in 2012 is 3678, 5070, 3870 crores, respectively.
So, the average is $$\dfrac{3678+5070+3870}{3}=4206$$
Given that the profit earned by A in 2015 is $$\dfrac{1}{6}th$$ of this average i.e.
$$\dfrac{4206}{6}=701$$ crores
So, the Investment = Revenue - Profit
or, Investment = 3678 - 701 = 2977 crores.
