Qualitative Reasoning

These are one of the easiest types of qualitative questions which can be practiced to have an insight of introductory sample exemplar qualitative reasoning type. Very different type of questions can be asked in examination. So the ultimate way to excel is these are to practice more and more questions of different types depending upon the level of difficulty. The more you practice the more quickly you get an idea to get the solution. So, have a look to these few basic type of QUALITATIVE APTITUDE questions.

QLRs SAMPLE Q1. If 36 + 25= 16 and 12+35 = 74 then 34+62 =?

      A. 96

      B. 69

      C. 510

      D. 105

Ans: Look at the question carefully. You can get the pattern only if you relate the first given part with the second. So here the first part which is given in the question is 36+25=16.

But only by observing this given you can’t find out the solution of the question being asked i.e. 34+62=?

36+25= 61, but it’s written as 16. It gives us a hint that probably the place value of 61 has been interchanged and is written in the form 16. This can be confirmed by observing the 2nd part, which is 12+35 = 74. Now this pattern is confirmed because the solution is written as 74 instead of 47. So, we can easily come up to answer by applying the same pattern. Hence the answer should be 69 as the addition was giving us 96 as the result.

 

QLRs SAMPLE Q2. Select the missing number from the given represents:

      6 x 3 = 13

      5 x 20 = 96

      11 x 7 = 67

      19 x 11 =?

a. 207              

b. 194            

c.191             

d.209

Answer: In any competitive examination the most vital thing to have a control over in is “TIME MANGEMENT”.  As we have already said the ultimate way to come up to the solution is to find the pattern of the given part of the question altogether. The more quickly you get the pattern the more quickly you would be able to solve these qualitative problems. Look at the pattern:

6 x 4 = 19      [6 x 4 = 24,               or, 24-5{*underlined value -1} =19]

5 x 20 = 96   {5 x 20 = 100           or, 100- 4{*underlined value -1} = 96}

11 x 5 = 44   {11 x 5 = 55              or, 55- 10{*underlined value -1} = 44}

19 x 11 =?    {9 x 11 = 209           or, 209- 18 = 191}

So, here is our answer c.191.

 

QLRs SAMPLE Q3. A box contains two dozen of glasses. If it is dropped on a concrete floor than which of the following cannot be the ratio of broken and unbroken cups?

      a. 2:1

      b. 6:1

       c. 5:1

       d. 3:1

Ans: We should look at every option and find out the unsuitable one. For example option a. says if broken glasses is 2x the unbroken glasses would be x. In that case the total glasses would be 3x.

From this we can observe that if x=8 we get total glasses as 24. Thus this seems to be a feasible option. Similarly option c and e is also feasible.

(c)5x+x= 6x=24                      =>x=4, an integral value.

(d) 3x+x=4x=24                      => x=6, an integral value of 24.

But (b) 6x+x=24                     => x= 24/7 which is not an integral value of 24.

Therefore © 6:1 can’t be the ratio of broken to the unbroken glasses.

 

QLRs SAMPLE Q4. A box contains two dozen of glasses. If it is dropped on a concrete floor than which of the following cannot be the ratio of total number of glasses to the unbroken glasses?

     a. 2:1

     b. 6:1

     c. 5:1

     d. 3:1

Ans: Let the number of unbroken glass be x. Therefore ratio of total number of glass to the unbroken glasses would be 24:x

a. 24/x= 2/1

=>x= 24/2

=>x= 12 (feasible)

b.  24/x = 6/1

=>X= 24/6

=> X= 4 (feasible)

c.  24/x= 5/1

=> X=24/5 (number of unbroken glasses can’t be in decimal but in whole number.)

Therefore option c. 5:1 cannot be the possible ratio.

QLRs SAMPLE Q5. In a certain code, 15789 written as XTZAL and 2346 are written as NPSU, How is 23549 written in that code?

      a) NPTUL

      b) PNTSL

      c) NPTSL

      d) NBTSL

Solution: A very easy and simple question to begin with. But these types of questions can be made difficult with a few brains storming logical twist. Let’s have a look to the solution of this question first:

15789 written as XTZAL,

That means X=1, T=5, Z=7, A=8, L=9.

Also, 2346 are written as NPSU,

That implies value of N=2, P=3, S=4, U=6

From the above two findings we can get the code for 23549.

2=N, 3=P, 5=T, 4=S, 9=L. So, code for 23549 should be NPTSL.OPTION ©.

 

QLRs SAMPLE Q6. Which of the following words will appear fourth in the dictionary?

     a. Sentiment

     b. Separate

     c. sentinel

     d. sentience

Answer: Very easy question which must not take more than fractions of second to answer. Out of all these four each one is starting with “se”, which is common in all four and we cannot come to any conclusion seeing the first two letters. And the third letter in option a, c, d is “n”. Whereas in option b it is “p”, and that would come at the last after option a, c, d. Hence option (b) separate will appear fourth in the dictionary.

 

QLRs SAMPLE Q7. Manav is facing west. He turns 45° in the anti-clockwise direction and then 180° in the clockwise direction. Finally he turns 90° in anti-clockwise direction. Which direction is he facing now?

  1. North-West
  2. North-East
  3. East
  4. South – East

Solution: Initially Manav’s position was towards west (fig1). After turning 45° in the anti-clock-wise direction his position changed towards south-west direction (fig.2). When he again turned 180° but this time in clockwise direction his position changed towards North-East direction (fig.3). Finally when he turned himself 90° anti-clockwise, his face was directed towards North-West. So, Manav is now facing towards 1) North-West direction.

QLRs SAMPLE Q8. Two N.C.C Cadet groups “A” and “B” are facing east and west directions respectively. They were given following commands —–left turn, about turn, right turn and left turn. At last, in which directions group “A” and “B” are facing now?

a) East, West

b) West, East

c) North, South

d) South, North

Solution: It is given in the problem that cadets of group A were facing towards East and group B towards West. (fig1).

So after following the first command both the groups turned to their left. Thus group A cadets were directed towards North and B towards south (fig.2).

Next command was to turn about. So after following it group A was facing towards South and B towards North. (fig3).

Next command was to turn right for both the groups, so group A turned from South to West and group B from North to East (fig4).

The final command was to turn left again. And following that they reached to the same direction where they were facing previously (in other words left turn cancelling out the right turn).(fig5)

Therefore now finally cadets of group A were facing towards South and group B towards East.

QLRs SAMPLE Q9. Time period is to second as frequency is to ____

  1. metre
  2. hertz
  3. joule
  4. Decibel

Answer: This type of question requires some relation. Here second is related to time period. As second is the SI unit of time period, similarly we need to know the SI unit of frequency i.e (2) Hertz.

 

QLRs SAMPLE Q10. Plough is to farmer as hammer is to ________.

  1. Tailor
  2. Blacksmith
  3. Painter
  4. Gardener

Answer: As we know the relation between a plough and a farmer i.e. plough is the most basic and important instrument used by the farmers. Similarly we need to know that hammer is the most basic and important instrument of (2) Blacksmith.

QLRs SAMPLE Q11. Which letter comes next in the series of letter?

                                 B AC B D C E D F ___

  1. C
  2. D
  3. E
  4. F

Answer:  Carefully analyze this series and try to find some relation within the series. If you can find that little analogy then you can easily come up with the solution.

5

As we can see that some pattern is there in the above series. Between two B’s two alphabets are there;first one is its preceding alphabet i.e. A second one is its successive alphabet i.e. C. Same pattern is visible in next four alphabets. Similarly we can say that next to F would be E. We can even tell the remaining two alphabets which will come after E. Did you get it ?

QLRs SAMPLE Q12. The number that will continue the series will be 1, 4, 9, 16, 25, ___.

  1. 36
  2. 32
  3. 20
  4. 48

Answer: This question is the most easiest and basic question of this type. The only trike to find the answer for this type of question is to look for the pattern in the given series. Try to find how the numbers are arranged, what is the relation between these numbers.
