IBPS Data Interpretation & Maths: Internal breakup
|Topicwise Breakup IBPS CWE PO/MT||2011||2012|
|Data Interpretation (DI)||20||15|
|number sequence-series(although reasoning topic but asked here)||5||5|
|%, profit loss, simple-compound interest||2||3|
|Number theory (Remainders)||0||1|
Obviously high priority = DI + BODMAS + Sequence-series.
And, Although not many questions are coming from the individual topics of percentages, profit loss, simple-compound interest, Time-speed-word, ratio, averages etc. but collectively, these topics help you raise your score by atleast 10 marks. Hence their Cost:Benefit is quite good. (compared to the amount of data you’ve to memorize to get 10 marks out of Misc.GK/Sports/Persons in News type MCQs.) Therefore, donot run away from Maths, prepare it diligently.
Ignore following topics
- Quadratic equations (ax2+bx+c=0)
- Geometry theory (except area-volume-perimeter)
- Coordinate Geometry
In Both previous years, at least 25 out of 30 questions came from Data interpretation+ BODMAS only
for both ^these topics, speed Maths=essential. Although internet is full of techniques of Speed Maths, Vedic Maths, but you must atleast master following techniques:
- Trachtenberg’s Techniques for:
- Multiplication by 5. It also indirectly helps you find out half (50%)of the given number as well. Because “m”x5= 10m/2. This helps you eliminate wrong answers quickly whenever you’ve find percentages.
- Multiplication by 9. It indirectly helps you guestimate the division by 11 as well. Because m/11=~0.9m
- Quick multiplication by 11. It indirectly helps you guestimate the number division by 9 as well. Because m/9=~0.11m
here is the wiki link: http://en.wikipedia.org/wiki/Trachtenberg_system
- Two digit division / long division / percentages approximation explained on
- Divisibility rules for various numbers (Given in NCERT, Quantitative aptitude books)
- Multiplication tables of 2 to 9, 12 to 25 must be learned by heart. Especially the tables of 13, 17, 19 and 23.
- Squares upto 29 and cubes upto 12 (required for the sequence-series questions and BODMAS)
- After that, as per your time and mood, learn the Vedic math techniques for finding cube-roots, square-roots of large numbers; three-digit multiplication etc.etc.etc.

for clearing the basic concepts: all of them available at Mrunal.org/download
for simplified techniques on %, Compound interest, permutation-combination-probability etc.
|Any one BankPO paperset||Require mainly for the Data interpretation practice.
|Any one book on Maths/Quantitative Aptitude||
#1: Data Interpretation (DI)
Can be of two types
|DI||with photo (Chart)||without photo|
||Addition-subtraction. (although sometimes will require %, ratio, division as well.)|
How is Bank DI different from other exams?
- In SSC CGL, LIC, State PCS exams, usually chart- based simple case. Doesn’t involve lengthy calculations.
- In IBPS/Bank PO, even if chart-based DI is asked, often you’ll be given an additional table showing ratio/sales etc. So you’ve to utilize the information from both chart + table to derive the answers.
How to approach?
