Being one of the most weighted sections, it demands focused hard work and regular preparation. The questions are formed from simple mathematical concepts yet too many candidates fear from this topic.
Quantitative aptitude consists of questions based on mathematical concepts and the ability to solve them as fast as one could. During the IBPS exam, it’s the speed of solving questions correctly that matters. It is therefore considered a good practice to exercise aptitude questions regularly and not loose time on solving questions during exams. For honing the skills of solving quantitative aptitude, one must know simple tricks to solve questions without committing common mistakes.
The topics that are covered in the IBPS CWE for Clerks, Probationary Officers, Management Trainees and Specialist Officers is mentioned with detail here. Have a look and practice the topics thoroughly.
Age: The age problems are common in every competitive exam because they are simple yet complex to solve. Based on simple formulas, ages relative to a ratio or present/ past / future years are given and then it is asked to find out the age of a person or all. The relation of a person is given and then questions are based on some assumptions and facts.
Averages: The questions are based on finding out the averages of numbers, ages, salaries, speed, marks, products etc. Given a problem in statement forms, the question can also be formed by giving a particular average and other terms and finding out a given number. The averages seem to be simple in understanding but the question formations with twists confuses candidates, therefore different sets of questions must be read and understood for scoring marks from this topic.
Alligations and Mixtures: The problems that include finding out the quantity or ratio of mixtures added to a liquid to make it more profitable. A certain ratio of two mixtures or components is given then a certain amount taken out from the mixture, some other quantity added or recommended to. It is then asked to find the percentage of a particular component in a mixture or the new ratio. These type of questions are common as they include concepts of profit, loss, ratios etc.
BODMAS Rule: The simple numerical questions on the simplification of numbers on precedence of operators are also asked in IBPS exams. At times there may not be distinct questions yet the BODMAS rule is useful in solving fractions, numerical equations etc. The rule states that in a complex equation the precedence of operators has to be followed to find answers.
Clock: The clock problems are based on simple understanding on the working of clock, hour, minute hands etc. The question usually is associated with a particular position of hands or time elapsed after a given starting time. It is very important to study the angles of hour hand, minute hand, about quarters, terms like half past, before two quarters to solve the questions related to clock.
Calendar Problems: The problems that are based on dates of a year based on which, day of the week is found out, comes under this topic. The calendars have specific day for a date, therefore questions in quantitative aptitude are asked given the data set with a particular week day and asking questions for a finding particular date and day from past or future.
Discount: The weaver of prices on products is known as discount. The quantitative aptitude question asked in IBPS containing discount, involve price depreciation or a minimum percentage on buying of products. It also includes questions were discount is given and original or selling price is asked about. The discount problems also include BANKER’S DISCOUNT where Banker’s discount is the simple interest that is calculated on the face value for the time period of due date of legal payments. The question associated with this type of question includes Banker’s discount, present value, true discount and banker’s gain etc.
L.C.M. & H.C.F.: The common set of numerical problems where highest or lowest factor is to be calculated comes under L.C.M. and H.C.F. The L.C.M. and H.C.F. problems also include finding out the lowest or highest number needed for divisions of set of numbers, finding out the next common instance happening, etc. The L.C.M. and H.C.F problems are easier to solve and saves time in competitive exams.
Profit and Loss: The profit and loss problems are clearly associated with gain and loss on selling or buying of products. The common problems based on Profit and Loss includes finding out the original selling price, cost price, selling price, loss or gain percentage, amount gained by profit or loss etc. They include basic addition, subtraction and percentage skills for solving questions.
Permutation and Combination: Finding out the chances of arrangement of a particular sequence from a given set of numbers, comes under permutation and combination. Out of the given total number of chances of happening, finding out the numerical value of arrangements that can be made in any order or a particular order, are found through permutation and combination problems. These problems are simple yet the complicated question statement baffles the students too much.
Probability: The ratio of occurrence of an event out of the total number of events is known as probability. It determines the possibility of happening of an event. In these type of problems, some facts are mentioned about happening or not happening of an event, then candidates have to find out probability of a given question.
Percentage: These questions are also common in finding out the percentage of numbers, people, goods, increment, decrement etc. from a given set of data. The percentage problems involve simple addition, subtraction, multiplication etc. The percentage problems are simple and one can score well by attempting these questions by simple tricks.
Ratio and Proportions: The fraction or ratio of quantities of two distinct things is solved in these types of questions. The problems are given as statements, with reduction or addition of other elements and based on that the quantity of an item or another one has to find the presence of one or the new ratio among two or more items has to be found.
Simple & Compound Interest: These involve calculation of interests in simple or compound manner. The interest is calculated on the principal amount, an annual rate, for a given period of time. Often the principal amount or amount of interest is mentioned and students have to find out the time, or rate, or any related term not mentioned in the problem. The compound interest are cumulative type of interests therefore are solved by using different formula. Candidates should clearly study the problem well and find out the right type of interest as mentioned in the question problem.
Square roots and cube roots: Problems based on finding out the square or cube roots of numerals as stated in the problem statement or solving equations based on the squaring or cube functions. The questions are generally given as variable or numeral cube or square format. One should know at least square and cube roots of numbers up to twenty to solve questions faster.
Time & Distance: The problems that ask to calculate distance between two points, or time taken to cover a particular distance on given average speed, comes under time and distance problem. By the formula of speed, time and distance one has to find out what has been asked in the question statement. The time and distance problems consists of facts, average or relative speed of moving objects, and one has to find how much time it took to cover the given distance moving by the given speed or vice-versa.
Time & Work: The working capacity of two or more persons or machines is mentioned in such problems, and then the time taken to work together or in a given time is asked. They involve simple fractional calculations and framing the question properly into equations. These problems help in finding out the share of work done by a person singly or with a group. The amount of work or time put to complete a work can also be asked under this topic.
Train, Boats and Streams: The questions related to the upstream or downstream speed of a boat or time taken to cross a train in similar or opposite directions. The topic covers movement of boats and trains related to each other. The questions related to the trains involves finding time taken to cover a moving or stationary object, time taken to cover a distance in time etc. The problems on boast involve finding out speed of stream, upstream or downstream rowing capacity, average speed for going up and down of a stream etc. These questions seem complex but are easier to solve once getting the concepts.
