Congratulations! You have completed your school years. While it is normal to feel a little sad over the end of happy school days, the motivated child always aims to look to the future while enjoying the present. Since you have landed on this article, I am sure you are one such motivated student who wants to understand what comes next in your life. To put it in short now is when you start to think about your life and the career choices you want to pursue. But, before that, you must be ready with certain skill sets which are necessary. One such skill is that of quantitative aptitude, and this is what we will be discussing today.
Companies find it incredibly hard to identify potential candidates for their businesses in this increasingly competitive world. With so many graduating students leaving universities each year, a mere degree is impossible to determine an individual’s strengths. This is where the necessity comes to develop a quantitative aptitude in order to outshine competing students.
Math is one of the most vital subjects taught to young students. It is taught to kids from a very early age along with languages. While math is commonly understood as one of the most dreaded subjects for students, its importance is often misplaced.
Math is not merely about multiplications and BODMAS and integrations or derivatives. Mathematics develops an extremely crucial part of your brain—logical thinking. This type of thinking is powered by quantitative aptitude.
So, how would you define quantitative aptitude? Individuals can understand and respond to a number of arithmetic problems. While most students would think it is only about mathematics and arithmetics, quantitative aptitude, or QA, often incorporates many facets of logical thinking, speed and critical decision making.
While quantitative aptitude allows people to measure the ability of an individual to assess a mathematical problem, that is only one part of it. Along with this, a quantitative aptitude allows people to identify a range of skill sets—logical and critical thinking, speed, pattern recognition etc.
Quantitative aptitude is important in solving mathematical issues and arriving at logical conclusions of arguments. Some of the earliest merchants in the world used their quantitative aptitude to design the way world trade functions most efficiently.
Moreover, quantitative aptitude has been closely linked with sound reasoning. Developing your quantitative aptitude allows individuals to assess a particular issue, design a flow to conclude, and in the process, eliminate improper answers. As our mathematics teachers told us in school, quantitative aptitude allows individuals to arrive at comprehensive solutions to problems. These problems may not necessarily involve mathematics, but the process that quantitative aptitude helps build greatly enables a student to find a reason-backed solution.
It is generally known that entrance exams in India are getting more competitive year on year. With an overflowing supply of graduating students, competitive exams over the years have become more stringent in their analysis of each student’s abilities.
Most competitive exams in India test students on key attributes of intelligence. This includes creative, critical and logical thinking. One such way to measure these attributes is by putting aspiring candidates under examination. While examinations of different fields measure different skill sets, quantitative aptitude is a standard test that most examinations contain. This is due to the need for mathematics in everyday life—from basic arithmetic functions to a comprehensive understanding of mathematical concepts in economics.
More than anything, quantitative aptitude and competitive exams test the ability of students to arrive at reasonable solutions in a very short period of time. These exams are not meant to test your ability to master basic mathematical concepts—your school was responsible for that. Competitive exams test the approach students take while answering questions. Thus, it is common for such exams to put in similar answers, confusing students. This is done to understand the method and approach of the student while answering the problem.
What does Quantitative Aptitude measure?
There are three main aspects of your intelligence that a quantitative aptitude test measures:
The real world is fast changing. For different fields, such as business, organisations need to be prepared for what is to come next. This is constructing an image of the future based on current trends. For example, changes in consumer behaviour tracked over a long time can allow a business to innovate a new product. Quantitative aptitude allows individuals to recognise the uniqueness in patterns over large databases.
Mathematics problems conclude at a solution. Creative minds find different ways to solve a problem. This is a skill that is developed through quantitative aptitude. It allows the brain to isolate the problem and work out different solutions that best fit the problem.
One of the most crucial aspects of quantitative aptitude is analysing issues. Most people can read questions. However, with a developed quantitative aptitude, individuals can analyse the parts of the question to assist in the solution. Extrapolated to real-life situations allows people to analyse the situation comprehensively and arrive at a solution keeping the available requirements in mind.
While most of the tests measure candidates’ quantitative aptitude on a written examination style test, there may be some fun and quirky questions that the interviewer may throw at you.
Question: If a bat and a ball cost 1.10 dollars and the bat costs 1 dollar more than the ball. How much would the ball cost?
Answer: When you hear this question, it sounds pretty easy. If the bat costs one dollar, the ball must cost 10 cents. However, this is the trick behind the question. The actual answer is 5 cents. This is because if the ball cost 10 cents, the total would be 1.20 dollars.
Question: If 12 men take 16 hours to finish building a wall, how long would it take four men to build that wall?
Answer: Since 12 men take 16 hours, one man takes almost 16×12=192 hours to finish the wall. Thus, four men will take 192/4=48 hours.
While this is the mathematically correct answer, a cheeky one can be 0 hours. This is because the 12 men have already built the wall!
Question: A company with 85 people have been infected by zombies. If the ratio of zombies to alive is 2:3, how many of them are still humans?
Answer: The answer is 51. While this can be done through proper fractions, a quick way exists too. This is because we know the ratio. Adding 2 and 3 gives us 5, which can now be divided by the total count to divide the group. This leaves us with 17 total groups of zombies and humans. Using this number and multiplying it by 3 gives us 51!
Question: Which odd number becomes even when you remove one letter from it?
Answer: Remember that most of the questions that test your quantitative aptitude test your approach and are often tricky. This is one great example. The answer is the number 7.
How do you ask? Well, if you remove one letter ‘s’ from seven, what are you left with? That’s right—even! While this was not an arithmetic question, it still tested your approach to solving the question.
Question: If you have five children and five apples, how do you distribute apples to every child while keeping one apple still in the basket?
Answer: This is another example of a tricky question that can be asked in a quantitative aptitude test. Again, here the interviewer is testing your approach to problem-solving.
The answer is quite simple. Give one apple to each of the four children, and give the last child the entire basket. This satisfies the premise that one apple remains in the basket while all five children receive an apple!
Question: You have two bottles—one 5L and one 3L. How do you measure 4L worth of liquid?
Answer: This can be explained in a number of ways. However, I will present a step by step approach.
Question: I was 25 years old the day before yesterday. Next year, I will turn 28. When is my birthday?
Answer: When this question is presented to candidates, often they start thinking about leap years. This is not the case for this problem. The answer is December 31st, i.e. new years eve.
