Direction: Study the following graph carefully and answer the questions given below it.
-
The average production of 1990 and 1991 was exactly equal to the average production of which of the following pairs of years?
-
- 1991 and 1992
- 1992 and 1994
- 1993 and 1994
- 1994 and 1995
- None of these
Correct Option: E
As per given graph in question,
The average production of 1990 and 1991 = (40 + 60)/2 = 100/2 = 50
The average production of 1991 = 60
Solve one by one option.
(A) The average production of 1991 and 1992 = (60 + 45)/2 = 105/2 = 52.5
(B) The average production of 1992 and 1994 = (45 + 50)/2 = 95/2 = 47.5
(C) The average production of 1993 and 1994 = (65 + 50)/2 = 115/2 = 57.5
(D) The average production of 1994 and 1995 = (50 + 75)/2 = 125/2 = 62.5
All the given option doesn't have average production of 50. So answer will be none of these.
