Data Interpretation Tricks – DI Shortcuts and Practice Problems
What is Data Interpretation?
Data Interpretation (DI) means nothing but understanding the given data to get inferences with the proper analysis of that data. To solve these type of problems, usage of data interpretation tricks is important for time management in competitive exams to do fast calculations.
In this type of questions, Some data is provided in the form of tables or bar charts or pie charts or in graph format and questions are asked based on the given data. Our task is to answer those questions simply by interpreting and analyzing the data in a smart way.
Data Interpretation is an important concept in almost every competitive exam today in quantitative aptitude section especially in all types of bank exams. In IBPS Bank Exams – 25 to 30 questions on data interpretation and data analysis are given and coming to SBI PO’s and State Bank Associate Bank PO’s recruitment Exam Pattern, The QuantitativeAptitude section itself is labeled as Data Analysis and Interpretation and more than 90% of the questions are given from data interpretation.
Let us discuss some facts on the topic of Data Interpretation Tricks with the analysis of previous SBI PO exam papers.
 In the year 2011, when SBI PO exam was conducted – Out of 50 questions of quantitative aptitude section 45 Q’s are asked from DI only.
 In 2013 SBI PO exam, we got 47 questions out of 50 Q’s from data interpretation.
 In the year 2014 SBI PO exam paper all the 50 Q’s are given from DI only.
With the analysis of previous exam papers, we can clearly understand the importance of having good knowledge & grip on data interpretation topics. So friends, if you people improve your mental ability in doing calculations in the quick and smart way by following some tips & tricks, shortcut methods, and formulas by applying them at the right place. For solving, Data Interpretation problems in less time. At first, need to selfassess your mathematical knowledge whether you have the following things in your mind.
Maths Tricks to Solve Data Interpretation
Remember the below basic maths to made our calculations faster in Data Interpretation (DI):
 Mathematical tables up to 20.
 Squares of numbers 1^{2 } to 30^{2} .
 Cubes of numbers 1^{3 to }^{ } 20^{3.}
 Powers of 2 up to 6.
 Powers of 3 up to 5.
 Fractional values 1/2, 1/3 ……… 1/20.

 Shortcut Methods and Formulas of Aptitude Topics.
With My personal experience of attempting SBI PO’s and IBPS PO Exams, I found in many bank exams of officer (PO) cadres that out of 50 questions in aptitude section. We found questions are asked based on the below strategy.
 Easy to solve – 5 Q’s
 Easy but lengthy(time taking) – 5 Q’s (Better not to touch such questions at first round)
 Moderate (can be solvable) – 5 Q’s
 Moderate to high – 5 Q’s
 Tuff – 5 Questions

Data Analysis and Interpretation for Bank Exams
For SBI PO Exam, data analysis and interpretation is the very important topic and if we focus this on proper planning and solving di questions using data interpretation tricks then, it’s not too hard to get the good score in this section.
From previous papers, we can expect mostly Data Interpretation problems are asked in the form of pie charts, line charts, bar graphs, mixed graphs, spider graphs etc.,
Mostly, we can expect questions on these topics – Percentages, Ratio, and Proportion, Averages. So friends, focus on those areas while practicing. Improve your calculation ability using shortcuts, formulas and speed maths tricks.
We feel calculation ability is key to get the high score in Quantitative Aptitude section and Data Interpretation. So improve your calculation ability through more and more practice of previous papers, learning shortcuts, formulas etc., without implementation learning shortcuts won’t help in exams. Practice more questions using DI shortcuts. Spend at least 1 hour daily to learn and implement shortcuts.
Data Analysis and Interpretation is just about playing with numbers using basic maths operations Additions, Subtractions, multiplications. Is it Right? Some data is given in the form of graphs, tables, charts. we need to analyze that data and answer the given questions.
Most of the bank exam aspirants have an idea on quantitative aptitude topics, formulas, and shortcuts but the thing is to know where to use the shortcut and when to use makes difference. We become familiar with those tricks is only through practice.
At First know SBI PO Syllabus, Exam Pattern, and Cutoff Score. What kind of questions is asking? and how many questions are asking? With the analysis of SBI PO Previous years Question papers from Data Interpretation Part.
1) Missing values in a tabular form have given last time. The data will be given and some values have been missed we have to analyze the given data and find missing values.
(or)
The data in a paragraph will be explained and we need to answer the questions with the analysis of that paragraph.
2) Pie charts, Bar charts, Line charts
3) Tables
4) Mixed Graph: 1 pie chart along with a tabular data, 1 bar chart along with a tabular data.
5) Spider graph.
 Averages are nothing but additions and division of given numbers
 The ratio is nothing but comparing two same values in different niches.
 The percentage is nothing but finding some value out of 100.
Most Common questions are asking in this format from Percentages
1) x is what % of y that means x/y * 100.
2) what percentage is x of y? i.e. x/y * 100.
3) x is what percent more than y = xy/y * 100
4) x is what percent less than y = yx/y * 100
5) percentage change between two particular values = [final – initial/ initial] * 100
we need to memorize some fractional values and percentage values. click here for basic percentage values and fractional values to memorize for doing fast calculations.

How to Solve Data Interpretation Questions Quickly
Solving DI Questions using Data Interpretation tricks is a technique, we should know which question to skip and which question to answer and don’t stick to lengthy calculations. Here are some tricks to solve data interpretation questions quickly.
DI is all about to test your calculation ability, how you can analyze and make decisions in less time.
1.Don’t waste time with lengthy calculations: According to our above analysis, some questions need lengthy calculations. First check, whether you can able to solve such questions using shortcut methods, maths tricks and by following calculation tips in less time.Trick: Need to know which question to pick and which question to skip and also where we have to use pen and where we have to mental calculations and where to use approximations while solving the questions.
2. Get answers by watching diagram:
For some questions, we can get answers by seeing the diagram itself carefully. No need to use pen and paper in solving that sort of questions. Avoid paperwork for simple calculations.
3. Use approx. values while solving:
In DI, for some questions, we don’t need to get exact answers. For such questions use approx. values to solve. This approach saves time.
4. Use Previous calculations if needed again:
While solving some questions, we require previously solved answers. For those questions, use previous answers and no need calculate the same sums again and again.
5. Important Topics to concentrate on Data Analysis and Interpretation:
Data Analysis and Interpretation majorly covers questions from these 3 areas of quantitative aptitude.

Ratios

Percentages

Averages
So, speed up your calculations and focus more on these topics in learning smart techniques, shortcuts, formulas etc.,
6. Follow Right Approach while Practice:
Speed along with accuracy plays the main role in one’s success in bank exams. Speed improves mainly through the right approach of practice. we have to analyze our performance in every go and make improvements in weak areas to have the better performance next time.
7. Use Data Interpretation Shortcut Tricks to save Time
Types of problems in Data Analysis and Interpretation:
There are various models 0f presenting data in Data Interpretation and Data Analysis.
 Table Charts
 Line Graphs
 Bar Graphs/Histograms
 Pie Charts
 Mixed Graphs
Let us first start with simple questions then we go for medium level questions and then go for highlevel DI questions to make you better understand the smart methods of Data Interpretation Tricks.
Before going to practice, we need to know some shortcut methods, formulas and some basic awareness of quantitative aptitude (QA) questions. Data Interpretation is the one which even better than QA to be confident about our answers.
