Quant Questions which appear in CAT are often tricky. As a result, an orthodox textbook method may not always be preferable in solving these CAT questions.

To solve CAT questions on Quant, it is imperative not only to be good with the concepts of major topics of Quantitative Aptitude for CAT but also to be good at applying various shortcuts and tricks to get to the answers quickly.

In this section, we have collected CAT  quantitative aptitude questions with detailed solutions, on important topics. The purpose of this section is to give good sets of questions which test the depth of your concepts on various topics of quantitative aptitude.

## What is the level of these Quant CAT Questions?

In CAT quantitative aptitude section, the questions are of varied difficulty level. In recent CAT papers, the overall difficulty level has dropped considerably. However, nothing can be predicted about the difficulty level of quant questions in CAT 2019.

As a result, one should always be prepared to negotiate any changes in the difficulty level of the exam. Keeping this in mind, most of the questions in this section are of moderate to the higher difficulty level.

## Who should take solve these Quant CAT Questions?

Most of the questions are of moderate to the higher difficulty level. Therefore,  we strongly suggest taking these questions only if you are done with the basic concepts of all the topics of quant.

However, if you are still in the process of learning the concepts, you may take the practice sets on the topic on which you have completed the concepts and have already practiced elementary level questions.

If you are about to start your preparation for CAT quant, then we highly recommend our article on ‘How to prepare for Quantitative Aptitude for CAT’.

## Are these Quant Questions in the form of test?

The quant questions are clubbed into many practice sets depending upon the topic and difficulty level. Each set has around 5-10 questions. Many of these questions have detailed explanations.

In fact, we have around 30 select quant questions across topics which have detailed VIDEO solutions. These 30 questions are part of our online CAT Quant Course.

You can take these practice sets as a test. For your reference, if you get more than 70% of these questions correct, then your preparation for the Quantitative Section is at par.

three arithmetic sequences S1, S2,S3 are given below.
S1: 1,4,7,10………991.
S2: 2,6,10,14,………..1014.
S3: 3,8,13,18,…………………..1008.
if a sequence Sx contains all terms which are common in all three sequences, then find the sum of terms of the sequence Sx.

1. Anurag Kumar says:

First common value which is present in s1,s2 and s3 is 58.
S1,S2,S3 has C.D of 3,4,5 respectively. So after 58, the value which will be common in all three will be( LCM (3,4,5) ) which is 60 ahead of it.. i.e 118.

So S6 will have 58,118,178,238 and so on…
the total number of term in the Sx sequence can be found as:
tn=a + (n-1)d
991= 58+(n-1) 60
n=16.

sum of AP= (n/2)(2a+(n-1)d)
= (16/2)(116+(16-1)60)
= 8128.

How did you get the first common term?

2. dhruvalsharma999 says:

d1 = 3
d2=4
d3=5
Taking lcm would, we’ll get 60
so series would be 60, 120,……etc

1. dhruvalsharma999 says:

i’ve made a mistake first term would be 58 & you can add lcm
series would be 58, 118, etc.

First, let’s try and find the first term of Sx, i.e. the first value that appears in all three series (S1, S2, S3).
We know, a_{n}=a_{1}+(n-1)d
Comparing S1 and S2 we get that: [4th term of S1 = 3rd term of S2]
And S2 and S3 we get that: [5th term of S2 = 4th term of S3]
Equating these two equations, we could conclude that [20th term of S1 = 15th term of S2 = 12th term of S3]
Again using the formula a_{n}=a_{1}+(n-1)d
Calculate any one of these:
Let’s say 15th term if S2 will be
a_{15}=2+(14)4 = 2+ 56 = 58
Therefore, 1st term of Sx = 58
Similarly, 2nd term of Sx = 30th term of S2
a_{30}=2+(29)4 = 2+ 116 = 118
For Sx, a=58 and d= (118-58) = 60
Now, 16th term of Sx = 958, which will be the last term of series
Therefore, Sum of series = S = n/2[2a + (n − 1) × d]
S = 16/2[2(58) + (16 − 1) × 60]
S = 8128

I just saw a video that says the number system has negligible weightage relative to arithmetic geometry and algebra. So, is it fine to be aware of the basic concepts of the number system and let go the difficult ones?
