In how many of the given years, were the exports from Company Z more than the average annual exports over the given years?

Answer: Option

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.

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.

What about 1993?

Guesi said:

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

The answer should be 3.

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

Hi @Amrita, agree with you, answer should be 5. Reason is that the comparison given is with the average exports every over given years.

Hence formula should be exports of z in given year/avg export done in that year.

The question is for "exports from Company Z" and not "average exports from Company Z". Hence, taking into account the exports of Z as compared to the average exports of all the 3 companies for each year, the answer should be 5. The question should have been more candidate.
