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.
Study the following line graph and answer the questions based on it.
Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
What is the difference between the total productions of the two Companies in the given years ?
19000
22000
26000
28000
Correct answer is C
From the line-graph it is clear that the productions of Company X in the years 1997, 1998, 1999, 2000, 2001 and 2002 are 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 and 148000 respectively.
Total production of Company X from 1997 to 2002
= 119000 + 99000 + 141000 + 78000 + 120000 + 159000
= 716000.
and total production of Company Y from 1997 to 2002
= 139000 + 120000 + 100000 + 128000 + 107000 + 148000
= 742000.
Difference = (742000 - 716000) = 26000.
Study the following line graph and answer the questions based on it.
Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
What is the difference between the number of vehicles manufactured by Company Y in 2000 and 2001 ?
50000
42000
33000
21000
Correct answer is D
Required difference = (128000 - 107000) = 21000.
The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.
Ratio of Value of Imports to Exports by a Company Over the Years.
In how many of the given years were the exports more than the imports ?
1
2
3
4
Correct answer is D
The exports are more than the imports imply that the ratio of value of imports to exports is less than 1.
Now, this ratio is less than 1 in years 1995, 1996, 1997 and 2000.
Thus, there are four such years.
The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.
Ratio of Value of Imports to Exports by a Company Over the Years.
If the imports of the company in 1996 was Rs. 272 crores, the exports from the company in 1996 was ?
Rs. 370 crores
Rs. 320 crores
Rs. 280 crores
Rs. 275 crores
Correct answer is B
Ratio of imports to exports in the year 1996 = 0.85
Let the exports in 1996 = Rs. x crores.
Then, 272/x = 0.85 => x = 272/0.85 = 320
Therefore Exports in 1996 = Rs. 320 crores.
The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.
Ratio of Value of Imports to Exports by a Company Over the Years.
What was the percentage increase in imports from 1997 to 1998 ?
72
56
28
Data inadequate
Correct answer is D
The graph gives only the ratio of imports to exports for different years. To find the percentage increase in imports from 1997 to 1998, we require more details such as the value of imports or exports during these years.
Hence, the data is inadequate to answer this question.
