Data Interpretation questions test one's ability in analysing data, inspecting the elements in data and interpreting them to extract maximum information from the given set of data or information. The data is usually given in the form of charts, tables and graphs.
Practise with our Data Interpretation questions and answers to help you know what to expect, improve your speed and confidence and be really prepared for the actual test.

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.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
1996
1997
1998
1999
Correct answer is A
The percentage increase in the amount invested in raw-materials as compared to the previous year, for different years are:
For 1996 = [ (225 - 120)/120 ] % = 87.5%
For 1997 = [ (375 - 225)/225 ] % = 66.67%
For 1998, there is a decrease.
For 1999 = [ (525 - 330)/330 ] % = 59.09%
For 2000, there is a decrease.
Therefore, there is maximum percentage increase in 1996.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
1996
1997
1998
1999
Correct answer is B
The percentage change in the amount invested in raw-materials and in the value of sales of finished goods for different years are:
Percentage change in Amount invested in raw-material:
For 1996 = [ (225 - 120)/120 x 100 ] % = 87.5%
For 1997 = [ (375 - 225)/225 x 100 ] % = 66.67%
For 1998 = [ (330 - 375)/375 x 100 ] % = -12%
For 1999 = [ (525 - 330)/330 x 100 ] % = 59.09%
For 2000 = [ (420 - 525)/525 x 100 ] % = -20%
Percentage change in value of sales of finished goods:
For 1996 = [ (300 - 200)/200 x 100 ] % = 50%
For 1997 = [ (500 - 300)/300 x 100 ] % = 66.7%
For 1998 = [ (400 - 500)/500 x 100 ] % = -20%
For 1999 = [ (600 - 400)/400 x 100 ] % = 50%
For 2000 = [ (460 - 600)/600 x 100 ] % = -23.33%
Thus, the percentage difference is same during the year 1997.
