First find out the average of every company for the three years then compare that average with the company's 2002-03 and 2003-04 values.

Please explain this question in detail,

According to question I calculated the avg yearly wise.

In 2002-03 = Avg production is 11.2.

In 2003-4 = Avg production is 9.4.

Then How to do find out.

"How many companies have shown production below their average production in 2002-2003, but have showed above the average production in 2003-2004".

In 2002-03 = Avg is 9.4
In 2003-04 = Avg is 12.6

Then honda Maruti and Hyundai shows below avg and honda gm and Hyundai show above avg. So, the answer is 3 companies.

Honda(2003-04)=14 is above Avg = 13.66.
GM(2003-04)=18 is above Avg = 16.
Hyundai(2003-04)=14 is above Avg = 9.66.
So, Honda + GM + Hyundai = 3.

The question is to find which companies show values below their average value in 2002-2003 and above their average value in 2003-2004.

First, find average values of all companies and check with 2002-2003 and 2003-2004.

Honda= (6+14+21) /3=13.66, in 2002-2003 value is 6 which is below of average value, but in 2003-2004 value is high.

The answer is C. Lets see the explanation:

First, find the average production in 2002-3 is 9.4, then find average production in 2003-4 is 12.8

Companies Below Above
Honda 6 14
GM No value 12,18
Martuhi 5,9 No value
HM 9 16
Hyundai 8 14

In question, they asked below average production in 2002 - 2003 (9.4) and above average production in 2003 - 2004(12.8). From the table, we have to select the company which is having both below and above values. They are Honda, HM, Hyundai.

Given is average of each company.

To get average of entire company:

(13.66 + 16 + 9.66 + 12.33 + 9.66)/5 = 12.26.
