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 and Explanation
Answer: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.

In 1999 = [ (65 - 45) x 100 ] % = 44.44%. 45 In 2000 there is a decrease in production. In 2001 = [ (75 - 50) x 100 ] % = 50%. 50 In 2002 = [ (80 - 75) x 100 ] % = 6.67%. 75 Clearlyl, there is maximum percentage increase in production in 1996.
5.

In how many of the given years was the production of fertilizers more than the average production of the given years?
A. 1 B. 2
C. 3 D. 4
Answer and Explanation
Answer:D
Explanation: Average production (in 10000 tonnes) over the given years = 1 (25 + 40 + 60 + 45 + 65 + 50 + 75 + 80) = 55. 8 Therefore The productions during the years 1997, 1999, 2001 and 2002 are more than the average production.
