Reasoning PYQs

No. of people- 6- L, M, N, O, P, Q.

Different colours- Red, Yellow, White, Green, Blue, Black. 

 

1- M takes the vaccine on three persons before the one who wears Black . 

2- The one who takes the vaccine while wearing black does not take in the last. 

3- Q takes three persons before the one who takes immediately after P. 

4- Q takes on any 2^nd date of any month. 

 

 

5- O takes two persons before the one who takes while wearing Yellow. 

 

 

6- L takes the vaccine before N and only one person takes the vaccine between them.

7- The one who wears Blue is taking the vaccine before the one who takes while wearing White and the same number of people who take the vaccine between N who wears White and the one who is wearing Blue is the same as between L and N. So case-1, case-2a and Case-2b(2) gets eliminated.

8- M does not wear red while taking vaccine.

 

So, Final arrangement;

 

 

Hence, Two people took the vaccine between the one who wore Black and M.

No. of people- 6- L, M, N, O, P, Q.

Different colours- Red, Yellow, White, Green, Blue, Black. 

 

1- M takes the vaccine on three persons before the one who wears Black . 

2- The one who takes the vaccine while wearing black does not take in the last.

6- L takes the vaccine before N and only one person takes the vaccine between them.

7- The one who wears Blue is taking the vaccine before the one who takes while wearing White and the same number of people who take the vaccine between N who wears White and the one who is wearing Blue is the same as between L and N. So case-1, case-2a and Case-2b(2) gets eliminated.

8- M does not wear red while taking vaccine.

 

So, Final arrangement;

 

 

Hence, O, M, L, and Q took the vaccine in odd numbered days month and N took the vaccine in even numbered days month so N is odd one.

7- The one who wears Blue is taking the vaccine before the one who takes while wearing White and the same number of people who take the vaccine between N who wears White and the one who is wearing Blue is the same as between L and N. So case-1, case-2a and Case-2b(2) gets eliminated.

8- M does not wear red while taking vaccine.

 

So, Final arrangement;

 

 

Hence, The one who takes the vaccine while wearing the Yellow colour on 2 May.

We can use the positional values of the letters/alphabets in the alphabetical series to map the letters in an easier manner.

According to the English alphabetical series, the positional values of letters are given as follows:

The letters are mapped as shown:

Pairs in the Forward direction → E – L, E – I, and I – L 

Pairs in the Backward direction → T – U

Hence, there are 4 pairs.

The least possible diagram for the given statements is as follows

Conclusions:

I. Some beds are chairs → False (It is possible but not definite)

II. Some sofas are books → True (Some sofas are chairs and all chairs are books so some sofas are also books)

Only conclusion II follows.

The least possible diagram for the given statements is as follows

Conclusions:

I. Some lions are women → False (It is possible but not definite)

II. Some men are goats → False (It is possible but not definite)

Hence, Neither conclusion I nor conclusion II follows.

Venn diagram for the given statement is as  follows 

Conclusions:

I. All Hindi being Bio is a possibility - True (Given Only a few Bio is Hindi means some Bio is not Hindi thus All Bio can never be Hindi but All Hindi can be Bio thus  All Hindi being Bio is a possibility follows)

II. Some Physics can be Hindi - False (Given Only Science is Physics means physics can not be other thus Some Physics can be Hindi not follows)

Hence, Only I follows.

9 family members: J, K, L, M, T, U, V, W and X

Using the following notations, we can draw the family tree diagram:

1. W is the son of M.

2. T is the brother of M’s sister K. 

  

3) U is the mother of T.

4. X is the father of M who is not the son of U.

So, M is the daughter of U and U is the wife of X.

5) J is the sister of U. 

6) B is the brother of W.   

7. D is the father of B.

Hence, there are four female members in the family.

Given:

5 designations - CEO, CFO, Manager, Clerk, and Peon

CEO is the senior most and Peon is the juniormost person. 

They have a different number of pens such that no two persons have the same number of pens.

Now,

1. Two persons are junior to T. It means T is a Manager.

2. The one who is just senior to the one who is Manager has 31 pens. It means CFO has 31 pens.

3. One designation lies between the one who has 31 pens and V. It means V is Clerk.

 

4. V is just senior to the one who has 43 pens. It means Peon has 43 pens.

5. There is one designation between the Manager and Y. It means Y can be either CEO or Peon.

Case I

 

Case II

 

6. V has 11 pens more and 9 pens more than S and M respectively. It means, V = S+11 and V = M+9. = S+11 = M+9. M-S = 2. M has more pens than S. In case I, M has 43 pens and S has 31 pens. But 45-33 is not equal to 2. So, the case I get eliminated. In case II, again there are two possibilities:

Possibility I - S have 31 pens. So M will have 33 pens and V will have 42 pens.

Possibility II - M has 31 pens so S will have 29 pens and V will have 40 pens.

Case II (a)

 

Case II (b)

 

7. The difference in the number of pens between Y and T is 14 and T has the least number of pens. So, Y – 14 = T. T has 43 - 14 = 29  pens. But no two persons can have the same number of pens. So, case II (b) gets eliminated as S also has 29 pens in it. 

The final arrangement is -

 

The total number of pens by the persons who are on the post of CEO and CFO is 33 + 31 = 64.

Hence, The correct answer is 64.
