Obviously high priority = DI + BODMAS + Sequenceseries.
And, Although not many questions are coming from the individual topics of percentages, profit loss, simplecompound interest, Timespeedword, 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 (ax^{2}+bx+c=0)
 Geometry theory (except areavolumeperimeter)
 Trigonometry
 Coordinate Geometry
 logarithm
Speed Maths
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 sequenceseries questions and BODMAS)
 After that, as per your time and mood, learn the Vedic math techniques for finding cuberoots, squareroots of large numbers; threedigit multiplication etc.etc.etc.
Booklist for IBPS Data Interpretation & Maths
NCERT Maths
for clearing the basic concepts: all of them available at Mrunal.org/download
Mrunal.org/aptitude
for simplified techniques on %, Compound interest, permutationcombinationprobability 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 

Example 


Essential Skill 
 Additionsubtraction. (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 chartbased 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?
Data interpretation doesn’t have much theory, except in piechart case (about conversion between % and circle degrees + when and where will the answer = “datainsufficient’)
 First master the minimum speed math techniques given above.
 Understand the Ratio related concepts.
 Understand the basic concepts of bar graph, piecharts etc. from Class 11 NCERT Statistics.
 Then start solving DI questions given the paperset book (Arihant / Kiran )
#2: BODMAS/Simplification
Bank exams (PO and Clerk) have an unwritten rule: first 1012 questions must be from BODMAS.
Here are two sample questions
 [Square root (6354)] x 34.993=?
 39.89% of 4331 divided by 58.779% of 5003=?
#1: first clear you basic concepts about following
Simplification (BODMAS)  NCERT Class 8 Chap 1 

Surds, indices 

Roots, squares, Cubes  Basics from NCERT Class 8 Chap 6 and 7. 
#2: then master the speed math techniques I listed earlier.
#3: Have a target of solving atleast 10 questions from your paperset every night, before going to sleep.
#3: Number sequenceseries
Although it is a reasoning topic, but they’ve asked it in Maths section. Consider following examples from previous IBPS papers
Q. In the following number series, only one number is wrong. Find out the wrong number
8424, 4212, 2106, 1051, 526.5, 263.25, 131.625
Answerchoices
 131.625
 1051
 4212
 8424
 263.25
Preparation source
 for the warm up exercise, go through chapter 3 (Classification) of RS Aggarwal’s Reasoning book
 Then maximum practice, go through your paperset book.
Bad thing about such questions: Sometimes you’ll be able to decipher the pattern within a minute, and sometimes, even after doing trialerror for more than 15 minutes, you might not see the pattern. Therefore, my suggestion is: during the exam, you put the entire set of sequenceseries questions on “mark and review”. (And when you’re done with other sections, come back and solve these questions at the end of exam.) Don’t waste initial momentum here.
#4: Linear Equations
Another ‘reliable’ area in IBPS. Sometimes, you’ll need to apply concepts of linear equations, to tackle questions from Timespeeddistance, ratioproportionvariation, averages etc as well.
Here are some samples questions from previous exams:
 Rubina could get equal number of Rs. 55, Rs. 85 and Rs. 105 tickets for a movie. She spends Rs. 2940 for all the tickets. How many of each did she buy?
 The ratio of the present age of Manisha and Deepali is 5 : X. Manisha is 9 years younger than Parineeta. Parineeta’s age after 9 years will be 33 years. The difference between Deepali’s and Manisha’s age is the same as the present age of Parineeta. What should come in place of X?
 Akash scored 73 marks in subject A. He scored 56% marks in subject B and X marks in subject C. Maximum marks in each subject were 150.The overall percentage marks obtained by Akash in all the three subjects together were 54%. How many marks did he score in subject C ?
Two things to be kept in mind, while solving questions on linear equation:
#1: keep minimum variables
Suppose the question runs like this “The sum of present ages of father and son is 56, and 5 years ago Son’s age was……….blah blah blah….find the present age of Father. ”
avoid this  do this 





#2: Cannot be determined
Suppose you end up with two equations like this:
 x+y=5
 y+z=6
Here you’ve two equations but three variables (x, y and z). You can never find out the unique value of x, y, z in such situation. Hence answer = “Cannot be determined”.
But sometimes, even two variabletwo equation set can be impossible to solve. For example
No solution  infinite solution 

 2x+ 3y=94x+ 6y=18 
To learn more about ^this, refer to NCERT Maths Class 10, Chapter3, table given on the page #9.
Preparation source for Linear Equations
 Understand basic concepts from
 NCERT Class 8 Chap 2 and 9.
 Then NCERT Class 9 Chap 4
 Lastly NCERT Class 10 Chap 3.
 Then maximum practice from your Quantitative Aptitude book and OR paper set book.
#5: PermutationCombinationProbability
Most of that can be solved without memorizing any formulas. In my opinion, this is the easiest of all math problems. Go through following articles

Alligations (WineWater Mixture)
Although not asked in previous exams but since it is an allied topic of “averages, so just to be safe, go through following articles
 [Aptitude] Alligations,Mixtures,Alloys: Water,Milk,Wine mixing: Weighted Average Made Easy for CSAT,CAT,CMAT,IBPS Aptitude
 [Aptitude] Alligation: Advanced applications in Interest rates, Profitloss, Average Wages (WineWater Concept)
#7: RatioProportionvariations
 NCERT Class 8 Chap 13.
 then max practice from your Quantitative Aptitude book and or papersets
 Also prepare the allied topic: “Partnership”, using this article http://mrunal.org/2012/05/aptitudepartnershipandprofitsharing.html
Sample Questions from previous papers

thanks sir
Sir Give me Speed Method to Solve Math
And English
Send Me Mail
sir
fast track objective arithmetic by rajesh verma is sufficient for IBPS po?
I bought mk pandey book(reasoning) as per suggestion of mrunal.he was right it has good concept building on topics like input output,assumption/reference,data sufficiency,Linear arrangement. but alas on the most important topic circular arrangement the book gives just one question (utter nonsense) as 78 questions on circular arrangement is a sure for ibps po(rs agarwal book covers the circular arrangement topic but the type of circular arrangement questions(arrangement with blood relationship,country,occupation etc) asked in previous ibps question is not there).so if anyone want to buy that book for circular arrangement.it would be a big mistake.for rest of the topics this book is good(concept buildingmk pandey,practicers agarwal)…
for circular arrangements.. refer to the book of puzzels “bsc publication”.
thanks mrunal sir
Thank you very much.

Kindly give solution by STD method.
If I were a girl, I would be in love with you, Mrunal!!! Thank god I am not 😉 It’s a great great work . तू एकदम वांड आहेस. I mean, simply fabulous. Many thanks for making all this data available to all of us.I read that someone had pointed out ‘Mrunal’ never cracked UPSC. But you are doing better than many other UPSC crackers. Keep it up & we all wish you a bright future ahead.
This time they may ask comparison based on quadratic equations bcoz in RRB 5 question on this were there.
i am not able to find the complete method where you explained everything about STD table ,please provide the link and if possible please arrange the articles (aptitude) under specific category so that any new aspirant doesnot end up frustated and find what he is looking for easily.
