Production of Fertilizers by a Company (in 1000 tonnes) Over the Years

2. 

The average production of 1996 and 1997 was exactly equal to the average production of which of the following pairs of years?

[A]. 2000 and 2001
[B]. 1999 and 2000
[C]. 1998 and 2000
[D]. 1995 and 2001

Answer: Option D

Explanation:

Average production (in 10000 tonnes) of 1996 and 1997 40 + 60 = 50.
2

We shall find the average production (in 10000 tonnes) for each of the given alternative pairs:

2000 and 2001 = 50 + 75 = 62.5.
2

1999 and 2000 = 65 + 50 = 57.5.
2

1998 and 2000 = 45 + 50 = 47.5.
2

1995 and 1999 = 25 + 65 = 45.
2

1995 and 2001 = 25 + 75 = 50.
2

Therefore The average production of 1996 and 1997 is equal to the average production of 1995 and 2001.
