You will have 45 minutes to finish the questions in this section. In addition, the level of difficulty in the mains is higher than in the prelims. Only attempt the questions that you are certain about. The importance of speed and accuracy in this situation cannot be overstated. Don't just guess an answer and mark it once you've calculated it.
Topic-wise Tips & Strategy for Quantitative Aptitude
1. Number Series
- In typically, a series of five questions is asked from this topic, with 2-3 of them being simple to answer. Currently, questions about missing and incorrect number series are common.
- Practice a lot and become familiar with the frequent patterns before attempting to apply them when answering questions.
- Number series questions just require the ability to analyze patterns. If you find it, you'll have your answer in seconds.
- Don't spend too much time on number series; if you can't figure out the pattern in under a minute, go on to the next question.
2. Simplification/ Approximation
- You can expect 5-10 questions from this subject. It is the simplest subject, and all that is required is a fast calculation speed.
- Follow the ‘BODMAS' guideline and do operations accordingly.
- When tackling approximation problems, avoid calculating the precise figure and instead use approximate values.
- Try to memorize the tables up to 25, squares up to 30, and cubes up to 20 to ace this section.
- It reduces the amount of time you spend calculating and hence boosts your speed.
- To answer this question, you can also apply the option elimination strategy.
3. Data Interpretation
This topic includes:
- Line Graph
- Bar Chart
- Table Graph
- Pie Chart
- Caselet
- Mixed Graphs
- Missing D.I
The most time-consuming and scoring section is data interpretation. In the Prelims exam, you should expect 1–2 sets of data interpretation, each with 5 questions, and 4–5 sets in the Mains exam. As a result, if you want to get a good score, you must grasp this part. In the Prelims, the level of questions from this topic is very straightforward, but in the Mains, it is a little more difficult and demands a thorough understanding of a variety of topics such as profit and loss, simple and compound interest, probability, time speed, and distance, and so on.
Here are some important tips to solve Data Interpretation questions:
- Work on your calculation skills: DI requires quick calculations such as addition, subtraction, multiplication, division, ratios, and percentage values, among others. To improve your speed, practice a lot of questions. Also, make an effort to do the calculations without using a pen and paper.
- Try to analyze answers from the graph: Many questions can be answered by just analyzing the data given in the graph. Figure out the answer by just eliminating options and visual estimation of the graph.
- Scanning the right data: In the case of tables and bar/line charts, students frequently make the error of selecting the incorrect data from the graph in a rush. Always be cautious while answering questions and consider the value thoroughly. Identify the values by glancing at the graph while practicing. Many times, candidates complete the question correctly but fail to check the units in the graph and options, resulting in incorrect answers being marked. As a result, while practicing D.I questions, make it a habit to observe units.
- Don't use calculators while practice: Don't use calculators while you practice questions as it will reduce your ability to calculate in exams.
- Prepare Arithmetic topics: You will frequently find questions from different topics in the D.I in the Mains exam, thus you must increase your grasp of various arithmetic topics to do well in the exam.
- Practice previous year D.I questions: Only by practicing will you be able to comprehend the nature of the questions. Check your level of preparation by practicing questions from past year's papers. After attempting, compare and analyze your solutions to learn about your weak areas and how to improve them.
Quant's Miscellaneous Topics
1. Profit and Loss
- Profit, Loss, and Discount is a crucial topic of Quantitative Aptitude.
- You will find the application of this topic in certain Data Interpretation questions as well.
- Learn the important formulas and have an understanding of its basics concepts.
Cost Price - The price at which an article is purchased, is called its cost price. It is abbreviated as C.P.
Selling Price - The price, at which an article is sold, is called its selling prices, abbreviated as S.P.
Profit/gain = S.P – C.P
Profit % = Profit/(C.P)×100
S.P = (100+gain % )/100 ×C.P
C.P = 100/(100+gain %)×S.P
Loss = C.P – S.P
Loss % = Loss/(C.P)×100
S.P = (100-Loss %)/100×C.P
C.P = 100/(100-Loss %)×S.P
2. Percentages
The percentage is an important topic to prepare. This topic is often used in the calculation of other topics like Profit & Loss, Approximation, Data Interpretation, etc. Learn some short tricks to calculate :
a. Calculate %: Find a% of b- a % of b = [b * a/100]
b. Express a/b as x %: a / b = (a/b * 100)
c. Increasing/Decreasing a number by a given %.
Increase by a% = [100 + a / 100] / Decrease by a% = [100 - a / 100]
d. % increase/decrease in a number
% increase = [increase / original number] * 100 % decrease =[decrease / original number] * 100
3. Averages
In the Prelims exam, you can expect one question from this topic. It's also utilised while solving Data Interpretation. Simply practise the questions to get a better understanding of how to use it. Learn the following basic formula:
Average of numbers= {Sum of Numbers / Total no. of numbers}
4. Simple Interest:
- Learn all basic formulas.
- Understand the short tricks to solve the questions.
- Know about the meaning of basic terms like interest, principal, the rate of interest, time, amount, etc.
- Formula: I = [( P X R X T )/( 100 )]
Where P = Principle, R = Rate of per annum, T = Number of years
5. Learn the conversion of Time Period and Rate of Interest.
5. Compound Interest:
- Learn the basic formula of it : A = P * (1 + (R / 100)) T
Where A= total amount that is to be paid at the end of the mentioned time
R = rate of interest
P = principal amount that was borrowed initially
T = time for which the money was borrowed
- I = A – P or P * (((1 + (R / 100)) T) – 1)
- Make sure you understand the difference between simple and compound interest. Compound interest, for example, applies the rate of interest to the original amount (Principal) borrowed as well as the accumulated interest during the preceding month.
- S.I. is constant over time, but C.I. fluctuates over the time period for which money was borrowed.
- In S.I. and C.I., the use of percentage topics is a must. To master this topic, you must have a firm grasp of the percentage chapter.
6. Time and Work:
Understand the fundamental concepts and the key formula. Its use is common in areas such as wages, data sufficiency, and pipes and cisterns. Here are some crucial concepts to follow.
- If A can do a piece of work in x days, then A’s 1-day work = 1/x
- If A’s one-day work is 1/x, A can finish the total work in x days.
- If A is x times as efficient as B then
The ratio of work done by A: B individually = x: 1
The ratio of time taken by A and B individually to finish the work = 1: x
7. Time, Speed, and Distance:
Understand the basic concept of it and learn important formulas
(i) Speed Distance Time formula is mathematically written as:- Speed = distance/time
The Formula of Time :- time = distance/ Speed
The formula of Distance:-Distance = (Speed * Time)
8. Partnership
Most exams include this as a major component. These questions are also extremely scoring. Check out the information below to learn more about this topic and how common questions are answered.
What is Partnership?
A partnership business is formed when two or more persons join hands to form a start-up or other business. Typically, they invest some money and gain profit from it. And the profit is divided among partners according to a predetermined ratio or their investment ratio. The following is the formula for calculating profit based on investment:
P1: P2 = C1×T1: C2×T2
Here, P1 = Profit for Partner 1.
C1 = Capital by Partner 1.
T1 = Time period for which Partner 1 invested his capital.
P2 = Profit for Partner 2.
C2 = Capital by Partner 2.
T2 = Time period for which Partner 2 invested his capital.
9. Ratio and Proportion
- To tackle the questions on this topic, you should memorize all of the basic formulas. To solve the questions fast and save time, learn all of the short tricks.
- Understand the definitions of basic words such as ratio, proportion, and their various kinds.
- Solve samples of problems from previous year's banking exams to gain a better understanding of how questions are asked.
10. Permutation and Combination:
Permutation & Combination has the direct application which is most widely asked in almost every banking exam. So basics of P&C must be very clear for solving those questions.
You must know about the term known as ‘factorial’. The product of the numbers starting from 1 up to a number ‘n’ is known as the factorial of number ‘n’.
It means n! = 1x2x3x4x5x6……..x(n-2)x(n-1) x n
In the permutation, we select the things and then arrange them to check out different possible ways of arrangement. So basically permutation is a two-step process.
The formula used for permutation is nPr = n!/(n-r)!
In combination, we select the things at random & check out the different possible ways of selection. So this is a one-step process. The formula used for the combination is nCr
nCr = n! / [r! x (n-r)!]
11. Probability
A word that can also be used in the place of ‘Probability’ is ‘Chance’. We all are well aware of the word ‘chance’. We use it in our daily life. Whatever we do, whatever we observe, there is always a chance that this is going to happen or not. When we want to find out the value of this chance in a quantitative form, at that point of time we use ‘Probability’ at the place of ‘Chance’.
Important Terms:
Experiment: Whatever we do, is called the experiment.
Outcome: Whatever is the result of the experiment is known as the outcome.
Favorable Outcome: The outcome in which we are interested is known as a favorable outcome.
Total possible outcomes: All possibilities related to the result of the experiment.
If one is aware of all the basic terms of probability, then the probability of any event/experiment can be found out by dividing the favorable outcome by total possible outcomes
