Try to apply some tricks to solve Quantitative Aptitude questions wisely

The Quantitative aptitude is the main subject asked in all levels of exams such as CAT, XAT, MAT, GMAT, CSAT, CLAT, UPSC, KPSC, GRE, LIC, ESIC, RRB, UGC, Career Aptitude in IT companies, SNAP, TNPSC etc. QA measures the numerical ability, accuracy in mathematics. The questions may range from numeric calculations to arithmetic reasoning, percentage analysis, quantitative analysis etc.

Quantitative aptitude not only tests your numerical skill set, but also tests your efficiency to maintain peace while reading through a question or any situation in a logical way of thinking without any frustration. There are some Quantitative aptitude tricks to learn to ease your exam’s QA part.

Use the options given to solve:

If you are given a complex sum to do just think a better way to do it. A Complex calculation is not to test your aptitude skill whereas only your smartness. The example is given below

  1. Question: 3812 + 5972 = ?

Options: A. 456284,   B. 658598,   C. 765454,    D. 501570

Now, instead of squaring manually, use your smartness

  • Square of 381 will definitely end with 1.
  • Square of 597 where 72 will end with 49, so the last digit would be 9
  • When you add 1+9=10 where the last digit ends with 0

So, the option for the question is D.

Attending Quantitative aptitude will be like a cakewalk if you understand the skills

  1. Question: Ages of X and Y are in the ratio 7:4, after 5 years, the ratio becomes 11:7. What is the age of X?

Options: A. 11, B. 18, C. 21, D. 28

You know the age of X must be a multiple of 7. So, you can quickly eliminate the option A and B. Now, if we consider the age of X is 21, after 5 years, the age of X is 26 years. However, 6 is not a multiple of 11, so eliminate the option C. when you consider the age of X 28 after 5 years, it will be 33 which is a multiple of 11. So, the option is D

Approach Strategically

In Quantitative aptitude, one should concentrate on four main topics

Number series: Though the questions will be tricky, your good practice on more number of questions helps to solve the numeric series questions in less time. So, it is advised to solve the questions from this topic as much as possible.

Quadratic equations\Inequalities: Based on the concept only you can touch the questions from this topic. So, concentrate on the concept.

Simplification\Approximation: With a right approach you can simply solve the questions from the topic. Since the questions are more of calculations, be strong in calculation part to crack the topic wisely.

Data interpretation: Based on tabular or bar graphs or pie charts, you will have two questions on data interpretation. The questions will be bit calculative, so you must learn tables to fast up your calculation level.

Other scoring chapters are Profit and loss, Average, Ration & Proportion, Interest and Percentage. Once you are well-versed in formulae, you can easily attend all of the questions from the above chapters.
