>>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?•••• Data interpretation doesn’t have much theory, except in pie-chart case (about conversion between % and circle degrees + when and where will the answer = “data-insufficient’) 1. First master the minimum speed math techniques. 2. Understand the Ratio related concepts. 3. Understand the basic concepts of bar graph, pie-charts etc. from Class 11 NCERT Statistics. 4. Then start solving DI questions given the paperset book Bank exams (PO and Clerk) have an unwritten rule: first 10-12 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 --NCERT Class 8 Chap 12--NCERT Class 9 Chap 1 •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. ••••Number sequence-series•••• 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 Suggestions: Bad thing about such questions: Sometimes you’ll be able to decipher the pattern within a minute, and sometimes, even after doing trial-error for more than 15 minutes, you might not see the pattern. Therefore, my suggestion is: during the exam, you put the entire set of sequence-series 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.
