3
4
5
Explanation:

Average annual exports of Company Z during the given period

 = 1 x (60 + 90 + 120 + 90 + 60 + 80 + 100) 7

 = Rs. 600 crores 7

= Rs. 85.71 crores.

From the analysis of graph the exports of Company Z are more than the average annual exports of Company Z (i.e., Rs. 85.71 crores) during the years 1994, 1995, 1996 and 1999, i.e., during 4 of the given years.

It will be 5 so the answer will be D.

Here, the average you have taken is wrong. For this question average of z is not required but an average of the three companies is required so the answer would be option D 5.

Z's Average = 600/7 = 85.71.
So, in the year
1994 = 90 , (90>85.71).
1995 = 120,(120>85.71).
1996 = 90,(90>85.71).
1999 = 100,(100>85.71).

Above 4years has more exports than average.

Remaining years were less than average.
i.e 1993 = 60 ,(60<85.71).
1997 = 60,(60<85.71).
1998 = 80,(80<85.71).

In majority questions explanation is not right. 93 is less that Z average why 93 is not considered?

How can you find this?

Then, in 1993 exports are 60 , which is less than 85.71.
in 1997 exports are 60, which is less than 85.71.
in 1998 exports are 80, which is less than 85.71.

How the avg of 85.7 is more than 100 In the year 1999?

Or the answer should be 5 if we will compare using the average of the 3 companies combined.
