How to Solve Data Interpretation DI Tips Tricks Guidelines

Hi guys, today I found some Tips and Tricks on "How to Solve Data Interpretation in Less time". Please read and follow the DI Guideline points carefully and practice them to solve quickly. Data Interpretation can be called as Comprehension of mathematics. In reading comprehension, we have to study the passage and answer the questions which will be followed by that. Similarly, in Data Interpretation, data is given in the form of graphs, charts and tables followed by questions. We have to study, understand and analyse the data to solve the questions.

  • Data is a collection of facts, such as values or measurements. It can be numbers, words, measurements, observations or even just descriptions of things.
  • Information refers to data being arranged and presented in a systematic or an organise form, so that some useful inferences can be drawn from the same. By data we generally mean quantities, figures, statistics, relating to any event.
What is Data Interpretation?
Data Interpretation is the extraction of maximum information from a given set of data or information. The data can be presented either in the form of a table or a bar chart or a pie chart or a line graph or as a combination of one of these formats.

Tips in solving DI questions:
The following tips may help in answering problem solving questions that involve data analysis:
  • Before starting DI section one should be very comfortable with numbers, calculations, fractions, percentages, averages, ratios. It helps in reducing the time required for solving the questions.
  • Scan the data briefly to see what it is about, but do not attempt to analyse it in too much detail before reading a question. Focus on only those aspects of the data that are necessary to answer the question.
  • Be sure to read all notes related to the data.
  • When possible, try to make visual comparisons of the data given in a graph and estimate products and quotients rather than perform involved computations. Remember that these questions are to be answered only on the basis of the data given, everyday facts (such as the number of days in a year), and your knowledge of mathematics.
  • Do not make use of specific information you recall that might relate to the particular situation on which the questions are based unless that information can be derived from the data provided.
Directions (Q.1-5): Study the following graph and answer the questions that follow.
The following graph shows the ratio of Imports and Exports of two companies A and B over the years.
How to Solve Data Interpretation DI Tips Tricks Guidelines

1. In how many of the given years were the imports more than the exports for company B?
1) 1
2) 5
3) 3
4) 4
5) None of these

2. If the total exports of company A in 2010 and 2015 was 38 crore, then what was the total imports of the same company for these two years together?
1) 60.8 cr
2) 43.6 cr
3) 58.8 cr
4) Can't be determined
5) None of these

3. What were the average imports of company A over the given years?
1) Rs.34 cr
2) Rs.14 cr
3) Rs.28 cr
4) Can't be determined
5) None of these

4. In how many years did company A show exports more than imports?
1) 2
2) 4
3) 1
4) 5
5) None of these

5. What were the exports of company A for the year 2012 if the imports were Rs.63 cr for same year?
1) Rs.42 cr
2) Rs.48 cr
3) Rs.52 cr
4) Rs.45 cr
5) None of these

1. Given the ratio of imports and exports ie, (I / E) imports more than exports means ratio should be more than 1
∴ in five years ratio is more than 1 for B

2. Ratio for 2010 & 2015 is 1.6 Imports
∴ Imports / Exports = 1.6

⇒ Imports = 38 × 1.6
                  = 60.8 crores

3. Average imports can not be determined as separated imports are not been given.

4. Imports less than exports means ratio should be less than 1.
∴ in one year (2009) ratio is more than 1 for A Imports

5. Imports / Exports = 1.4
⇒ Exports = 63 / 1.4
                  = 45 cr
