Introduction to Data Interpretation problems
- 1. The average production of 1990 and 1991 was exactly equal to the average production of which of the following pairs of years?
Options- A. 1991 and 1992
- B. 1992 and 1994
- C. 1993 and 1994
- D. 1994 and 1995 Discuss
Correct Answer:
Explanation:
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.
- 2. What was the difference in the production of food-grains between 1991 and 1994?
Options- A. 10000 tons
- B. 15000 tons
- C. 500 tons
- D. 5000 tons Discuss
Correct Answer: 10000 tons
Explanation:
Difference in the production of food-grains between 1991 and 1994 = Production of food-grains in 1991 - Production of food-grains in 1994
Put the value by seeing the graph
Difference in the production of food-grains between 1991 and 1994 = ( 60 ? 50 ) x 1000 = 10 x 1000 = 10,000
- 3. In which of the following years was the percentage increase in production from the previous year the maximum among the given years?
Options- A. 1991
- B. 1993
- C. 1995
- D. 1990 Discuss
Correct Answer: 1990
Explanation:
Check given option one by one.
Option (A),
Percentage increase in production in 1991 = {(Production in 1991 - Production in 1990)} x 100 % / Production in 1990
Percentage increase in production in 1991 = {( 60 - 40 )} x 100 % / 40
Percentage increase in production in 1991 = 20 x 100 % / 40
Percentage increase in production in 1991 = 100 % / 2 = 50 %
Option (B)
Percentage increase in production in 1993 = {( Production in 1993 - Production in 1992 )} x 100 % / Production in 1992
Percentage increase in production in 1993 = {( 65 - 45 )} x 100 % / 45
Percentage increase in production in 1993 = 20 x 100 % / 45
Percentage increase in production in 1993 = 4 x 100 % / 9 = 400/9 = 44.44 %
Option (C)
Percentage increase in production in 1995 = {( Production in 1995 - Production in 1994 )} x 100 % / Production in 1994
Percentage increase in production in 1995 = {( 75 - 50 )} x 100 % / 50
Percentage increase in production in 1995 = 25 x 100 % / 50
Percentage increase in production in 1995 = 100 % / 2 =50 %
Option (D)
Percentage increase in production in 1990 = {( Production in 1990 - Production in 1989 )} x 100 % / Production in 1989
Percentage increase in production in 1990 = {( 40 - 25)} x 100 % / 25
Percentage increase in production in 1990 = 15 x 100 % / 25
Percentage increase in production in 1990 = 15 x 4 % = 60 %
- 4. What was the percentage drop in the production of food-grains from 1991 to 1992?
Options- A. 15
- B. 20
- C. 25
- D. 30 Also asked in: Bank Exams
Correct Answer: 25
Explanation:
- 5. In how many of the given years was the production of foodgrains more than average production of the given years?
Options- A. 2

Correct Answer: 4
Explanation:
- 6. What is the approximate average production of roses (in thousands) across all the states?
Options- A. 21
- B. 20
- C. 19
- D. 18 Discuss
Correct Answer: 18
Explanation:
- 7. Which of the following State(s) contribute(s) less than 10 % in the total rose production?
Options- A. Only Rajasthan
- B. Rajasthan, Karnataka
- C. Rajasthan, Karnataka, Haryana
- D. Rajasthan, Karnataka, Haryana and Gujarat Discuss
Correct Answer: Rajasthan, Karnataka, Haryana
Explanation:
Total rose production = ( 15000 + 12500 + 12450 + 20000 + 12400 + 22500 + 22400 + 25000 ) = 142250
% Rose Production increase in State = Rose production in state x 100 / Rose production in All state
% Rose Production increase in Gujrat = Rose production in Gujrat x 100 / Rose production in All state
% Rose Production increase in Gujrat = 15000 x 100 / 142250
% Rose Production increase in Gujrat = 1500 x 100 / 14225
% Rose Production increase in Gujrat = 300 x 100 / 285
% Rose Production increase in Gujrat = 60 x 100 / 57
% Rose Production increase in Gujrat = 6000 / 57 = 10.54 %
Similarly Calculate the % Rose Production increase in all states one by one and compare them.
Percentage production of rose in the States (the lowest four states)
