Let's tabulate the chart ,
Since difference in average sales is given , Difference in sales can be found by multiplying it by 7
For example
Let the sales of A be in 2009 - 2015 respectively.
Let the sales of B be
Given that
Hence A- B = 214.29 * 7 = 1500
Similarly, all the remaining differences in sales can be calculated
a1, a2, a3, a4, a5, a6, a7
b1, b2, b3, b4, b5, b6, b7
7 −
(a1+a2+a3+a4+a5+a6+a7)
7 =
(b1+b2+b3+b4+b5+b6+b7)
214.29
Let the sales of A in 2013 be 'a', C in 2010 be 'c', D in 2012 be 'd' .
Total sales of A = (6800+a)
B = 5800
C = (7400+c)
D = (5700+d)
E = 7000
A - B = 6800+a - 5800 = 1500 => a = 500 crores
B - C = 5800 - 7400 - c = -2400 => c = 800 crores
D - E = 5700 + d - 7000 = -700 => d = 600 crores
Hence C is the correct answer.
