The Data Sufficiency Section in The IBPS exam is aimed to test your reasoning ability ‘quantitatively’. This is different from the problem solving section, which is tests you on your ability to manipulate numbers. If you end up doing a lot of number crunching in this section, you are on the wrong track. The followings are the basic requirements regarding the building of the concept as that is very important for the whole preparation of the IBPS exam. Let’s take a look:
The Data Sufficiency concepts in this section are fairly basic and at the knowledge level of nearly all college-bound high school student. Besides basic arithmetic, the questions also tests you on the concepts of averages, algebra, fractions, factoring, decimals, and principles of geometry such as triangles, circles, and determining the areas and volumes of simple geometric shapes.
Tips and Strategies
The IBPS Data Sufficiency section aims at measuring your ability to distinguish facts from assumptions. The same rules which hold for problem solving hold here: Do not make or rely on visual assessments of a diagram accompanying a geometry question to get data on angle sizes, parallel lines, etc. And of course do not make the mistake of carrying information over from one question to the next. Obviously, each question in the section stands independently. You can be sure that at least a few questions in the section will try to capitalize on this common fallacy. Do not get bogged down with calculations, as mentioned earlier, these questions seek to test your ability to think conceptually, not make long calculations.
The Elimination Process
The IBPS Data Sufficiency section as mentioned earlier is ideally suited to use the process of elimination. As long as you look at each statement individually, it does not matter which statement you look at first. So if you find statement 1 confusing or difficult, look at statement 2 and eliminate the answer choice based on what you conclude. Watch out for statements which mean the same. Sometimes, both the statements convey the same information. In this case you can easily know that the correct answer choice is either D or E. One of the popular tricks in this section is to mix ratios and percentages.
You should watch out for the tendency to assume that the variables given are all positive integers. For example in an abstract questions such as “What is the value of x?”, x could be a fraction and/or a negative number. Make real world assumptions.
Nothing beats Practice
The more time you do IBPS data sufficiency questions, the better you can internalize and use the tips given above. The practice will also help you increase your comfort level with this type of questions and you will get to know which areas in math you might need to brush up again. Take as many live IBPS practice tests as possible so that when the day comes, you will be able to think on your feet and crack the exam.
