4
Correct answer is D
Average production (in 10000 tonnes) over the given years
= (25 + 40 + 60 + 45 + 65 + 50 + 75 + 80)/8 = 55
Therefore the productions during the years 1997, 1999, 2001 and 2002 are more than the average production.

Production of Fertilizers by a Company (in 1000 tonnes) Over the Years
2002
2001
1997
1996
Correct answer is D
The percentage increase in production compared to previous year for different years are:
In 1996 = [ (40 - 25)/25 x 100 ] % = 60%
In 1997 = [ (60 - 40)/40 x 100 ] % = 50%
In 1998, there is a decrease in production.
In 1999 = [ (65 - 45)/45 x 100 ] % = 44.44%
In 2000, there is a decrease in production.
In 2001 = [ (75 - 50)/50 x 100 ] % = 50%
In 2002 = [ (80 - 75)/75 x 100 ] % = 6.67%
Clearly, there is maximum percentage increase in production in 1996.

Production of Fertilizers by a Company (in 1000 tonnes) Over the Years
What was the percentage increase in production of fertilizers in 2002 compared to that in 1995?
320%
300%
220%
200%
Correct answer is C
Required percentage = [ (80 - 25)/25 x 100 ] % = 220%

Production of Fertilizers by a Company (in 1000 tonnes) Over the Years
2000 and 2001
1999 and 2000
1998 and 2000
1995 and 2001
Correct answer is D
Average production (in 10000 tonnes) of 1996 and 1997 (40 + 60)/2 = 50
We shall find the average production (in 10000 tonnes) for each of the given alternative pairs:
2000 and 2001 = (50 + 75)/2 = 62.5
1999 and 2000 = (65 + 50)/2 = 57.5
1998 and 2000 = (45 + 50)/2 = 47.5
1995 and 1999 = 25 + 65)/2 = 45
1995 and 2001 = 25 + 75)/2 = 50
Therefore the average production of 1996 and 1997 is equal to the average production of 1995 and 2001.

Production of Fertilizers by a Company (in 1000 tonnes) Over the Years
What was the percentage decline in the production of fertilizers from 1997 to 1998?
33%
20%
25%
21%
Correct answer is C
Required percentage = [ (45 - 60)/60 ] % = -25%
Therefore there is a decline of 25% in production from 1997 to 1998.
