Giving an AMCAT is not as easy as it seems, if you’re confused about how you can prepare for the exam. A skill assessment test, the AMCAT test analyses students on language, quantitative ability and logical reasoning (apart from domain knowledge). And showcases your strengths on these parameters to more than 2000+ recruiters.

We have earlier helped students with guidelines to cracking the AMCAT English Language Module and the AMCAT Logical Reasoning Module. Now, we consider the next – the AMCAT Quantitative Ability module – what is it all about, how you can prepare for it, sample papers you can consider and how you can easily crack it.

AMCAT Quantitative Ability

company research

One of the three compulsory sections, the AMCAT Quantitative Ability test assesses the numeric ability of a candidate in core technical and non-technical aspects. Here is everything that you need to know about it:

What is Quantitative Ability?

Quantitative Ability refers to your ability and proficiency to understand and solve mathematical problems and calculations. A measure of quantitative ability is taken as part of most competitive exams, be it the CAT, MAT or GRE.

A skill assessment in quantitative ability checks your ability in basic mathematics – arithmetics, graphs, tables and percentages. These basics are needed in most jobs and career profiles.

How to prepare for quantitative aptitude test?

The AMCAT quantitative aptitude test is an 18-minute module, with 16 questions that a candidate must answer. As the overall AMCAT test is adaptive in nature, mistakes lead to easier questions (and a lower score), while correct answers would lead to tougher ones (and a higher score).

The syllabus includes:

Basic Mathematics:

Divisibility, HCF and LCM, Numbers, Decimals and Power, Logarithms, Inverse, Permutation and Combinations and Probability

Applied Mathematics:

Profit and Loss, Simple and Compound Interest, Time, Speed and Distance, Inverse

Fresher Jobs for High Scores in Quantitative Ability:

A good score in quantitative ability reflects well for those looking for roles in content development, business consulting, HR/Admin, iTeS/BPO, Marketing, Customer Management, Hotel Management and Life Sciences. You could also consider a career in Sales, Engineering and IT.

Solving a sample question paper for Quantitative Ability:

Here are a few common questions in these areas, alongside their solutions:

Basic Mathematics:

The questions are related to arithmetic ability, logarithms and probability. Here are a few questions that you can consider:

The first one is easy:

An example of a basic mathematics question in the AMCAT quantitative aptitude test.
An example of a basic mathematics question in the AMCAT quantitative aptitude test.

Correct answer: Option 1

Solution:

Step 1: Find the LCM of the numerators.

LCM (147, 30) = 1470

Step 2: Find the HCF of denominators.

HCF (64, 44) = 4

So, the LCM of 147/64 and 30/44 is (LCM of Numerators) / (HCF of Denominators) = 1470 / 4 = 735/2

Consider this:

The Correct answer: Option 3

Solution:

Let’s say the 7 numbers are a, b, c, d, e, f and g.

Given that:

(a + b + c + d + e + f + g) / 7 = 60

(a + b + c) / 3 = 50

(e + f + g) / 3 = 70

To find: The remaining number i.e. ’d’

Solving the averages we get:

(a + b + c + d + e + f + g) / 7 = 60

a + b + c + d + e + f + g = 420

(a + b + c) / 3 = 50

a + b + c = 150

(e + f + g) / 3 = 70

e + f + g = 210

Inserting the values obtained above in the equation given below:

a + b + c + d + e + f + g = 420

150 + d + 210 = 420

360 + d = 420

d = 60

Applied Mathematics:

Questions concerning Profit and Loss, Simple and Compound Interest, Time, Speed and Distance, Inverse – those which require careful deliberation and the use of mathematics to seek solutions are part of this segment.

Consider this question:

An example of an applied mathematics in the AMCAT test.
An example of an applied mathematics in the AMCAT test.

Correct answer: Option 3

Solution:

Total amount paid by the customer for construction work = $600

Amount spent on the purchase of materials = 3/5 of the total amount = 3/5 * 600 = $360

Remaining amount = $(600-360) = $240

Amount spent on travelling = 1/5 of the remaining amount = 1/5 * 240 = $48

Total amount spent = $(360+48) = $408

Amount left after both the deductions = $(600-408) = $192

And this one:

Correct answer: Option 3

Solution:

Let’s assume that the principle amount is $100.

It is given that when this amount ($100) is invested for 10 years, the simple interest becomes double of this amount i.e. it becomes $200.

So, the interest rate being offered can be calculated as:

Simple Interest = (P * R * T) / 100

Where,

P = Principle

R = Rate of Interest

T = Time (in years)

200 = (100 * R * 10) / 100

200 = 10 * R

R = 20%

And finally, here’s the last one:

Correct answer: Option 1

Solution:

Let the speed of the river be ‘x’.

Given:

Distance of rowing the boat = 30 miles

Speed of the boat in still water = 15mph

Time taken to row the boat in the river = 4.5 hours

The speed of the boat when downstream is, (15 + x) and when upstream is, (15 – x).

Time = (Distance / Speed)

4.5 = [30 / (15 +x)] + [30 / (15 – x)]

4.5 = [30 (15 – x) + 30 (15 + x)] / [(15 +x) (15 – x)]

Applying the identity: (a + b) (a – b) = a 2 – b 2 , in the denominator:

4.5 = (450 – 30x + 450 + 30x) / (15 2 – x 2 )

4.5 = 900 / (225 – x 2 )

4.5 (225 – x 2 ) = 900

1012.5 – 4.5 x 2 = 900

4.5 x 2 = 112.5

x 2 = 25 and therefore, x = 5 and x = -5. Ignoring x = -5, the speed of the river is 5 mph.

Keen on preparing further? General preparation books for CAT and GMAT can help – you could also look into AMCAT sample papers and study accordingly.

  11. Hello Ashish,

    It depends on how well you prepare for the AMCAT Test and subsequent interviews. A good performance in the AMCAT Test helps you connect to relevant, matched jobs, which you may not get access to owing to marks, location, lack of contacts. To answer your question honestly, would recommend you to go through the AMCAT success stories.

  12. I have given amcat test but my marks was very less in quant English and comp.science… Plzz help me to make strategy to qualify..suggest me some section which I can prepare and get qualify

  13. Hi Sonali,

    We recommend preparing as per the syllabus (explained in our Cracking the AMCAT series) for Quants, English and Computer Science.
    Remember – there is no negative marking, so try to answer everything.
    Here are the specific areas you would need to target:

    1. For English:
    Vocabulary, Grammar (Correcting Errors, sentence construction, subject-verb, Tenses, Speech and Voice), Reading Comprehension. Focus on getting the Grammar elements right, followed by the Reading Comprehension and then vocabulary.

    2. For Quants:
    Focus on Applied Maths (Profit and Loss, Simple and Compound Interest, Time, Speed and Distance AND Inverse), followed by questions for Basic Maths (LCM, HCF, Divisibility, Numbers, decimal fractions and power).

    3. For Computer Science:
    Operating System and Computer Architecture (Basics of OS, Computer Architecture, Process Management and Synchronisation, Memory and I/O Management), D BMS (Data model, Relational Algebra and SQL, Normalisation, Architecture, Indexing) and Computer Networks (Basics of networking and communication, OSI, TCP/IP layers and protocols, Network Devices and Routeing Algorithms)
    DBMS is often cited by candidates as being a high difficulty segment in the test. Focus here, followed by OS and Networks.

    Hope this helps.

  14. Extremely helpful content! The choice of questions are suitable as well as challenging for first-timers. Both basic and applied mathematics are important questions to grasp. Quantitative Aptitude is a tough task but very manageable thanks to content such as this and yours.

  15. Hiiii..
    I am pursuing b.tech from CSE…
    Anyone helps me…how to crack amcat test..?
    I don’t think know which type of questions asked . So, plsss anyone tell me related this and which section is more necessary to crack this..

  16. Hi Aditi,
