Classes Material for Quantitative Aptitude: Data Interpretation

Glide to success with Doorsteptutor material for CAT : get questions, notes, tests, video lectures and more- for all subjects of CAT.

As many of you might know that many readers shared motivational articles for bank exams. I analyzed comments of all these articles, one of the most common complaint was “These articles are not going to improve my score” . Today I planned to share a detailed plan for Quantitative Aptitude section. Most of the candidates find very difficult to crack this section and this is the culprit behind your failure.

Data Interpretation

  • In IBPS, SBI and other recruitment exams you can find 10 - 20 questions from this chapter. This is very lucrative. But there is a catch!
  • Few years back DI sets used to very easy but now as level of competition is increasing, level of difficulty is increasing. In case you invest 20 - 25 minutes to these questions and at the end you found it impossible to find exact answer, You Fail.
  • Be strategy for DI part is - Never try to find exact answer. I am not suggesting you make lame guesses but while solving a bar chart question you can easily tell which company has highest growth. Try to solve it visually.
  • Candidates must read Data Interpretation techniques.

Data Sufficiency

  • Data sufficiency is a popular chapter in CAT and XAT, till 2011 I never saw DS questions in bank exams but there were 5 - 10 questions from this chapter in IBPS PO, IBPS SO, IBPS Clerk and SBI PO.
  • Biggest mistake that candidates commit to solve DS questions is that they try to solve the question wherever you need to find whether given statement is sufficient to solve the question or not.
  • I made a quick video as well detailed post on Data sufficiency. Go through these posts.

Time and Work & Time and Distance

  • I use efficiency method to quickly solve time and work questions. For example, A can do a job in 10 days that means he can do 10 % of the job per day. By using this method, you can solve any question related to this chapter within seconds.
  • I wrote a detailed post along with videos for Time and Work chapter here.
  • Read detailed post on Time and Distance here.


it՚s a tricky chapter. It takes few minutes to complete this chapter, read any quantitative aptitude book. I made a quick video on this chapter.

Allegation and Mixture

  • Nobody takes this chapter seriously because they don՚t know that allegation method can be applied to any question where 2 things are mixed. Allegation method can be applied to Time and Work, Time and Distance, Profit and loss, Data Interpretation and there is no limit for its application.
  • I wrote a detailed post on Allegation method with Video.


Although Geometry was not a part of bank exams syllabus but now, we can notice at least 3 - 4 questions in from this chapter in almost every exam. Difficulty level is very easy; you just need to learn 10 - 12 basic theorems and formulae. During exams these are high scoring questions. You can solve this questions visually or just by drawing the diagrams.
