Reasoning PYQs

Twelve persons are sitting in two parallel rows containing six person each.

In row-1 : P, Q, R, S, T and U

In row-2 : A, B, C, D, E and F

1. Q sits at one of the end of the row.

2. One person sits between P and Q.

The possible arrangement is as follows:

3. Three persons sit between S and T and S does not sit at any end of the line.

4. E sits opposite to S.

5) U is not an immediate neighbour of T.

6. C sits second to the right of B.

7. Either B or C sits at end of the row.

8. P does not face B and T does not face C.

9. R sits opposite D.

10. A sits immediate right of D.

11. F sits second to the right of E.

(This will eliminate Case 2)

All the persons except (P, F) are sitting opposite each other.

Hence, P, F  does not belong to the group.

In row-2 : A, B, C, D, E and F

1. Q sits at one of the end of the row.

2. One person sits between P and Q.

The possible arrangement is as follows:

3. Three persons sit between S and T and S does not sit at any end of the line.

4. E sits opposite to S.

5) U is not an immediate neighbour of T.

6. C sits second to the right of B.

7. Either B or C sits at end of the row.

8. P does not face B and T does not face C.

9. R sits opposite D.

10. A sits immediate right of D.

11. F sits second to the right of E.

(This will eliminate Case 2)

R faces D and immediate right of R is U.

Hence, U is the correct answer.

Twelve persons are sitting in two parallel rows containing six person each.

In row-1 : P, Q, R, S, T and U

In row-2 : A, B, C, D, E and F

1. Q sits at one of the end of the row.

2. One person sits between P and Q.

The possible arrangement is as follows:

3. Three persons sit between S and T and S does not sit at any end of the line.

4. E sits opposite to S.

5) U is not an immediate neighbour of T.

6. C sits second to the right of B.

7. Either B or C sits at end of the row.

8. P does not face B and T does not face C.

9. R sits opposite D.

10. A sits immediate right of D.

11. F sits second to the right of E.

(This will eliminate Case 2)

Hence, Q - A sits at end of the row.

The code is as follows:

Hence, the code for "all" is "7".

1) S is the son of Q.

2. Q is the daughter of R.

3. P is the daughter of T.

4. P and Q are siblings.

5. U is the father of S.

Using symbol table the family tree diagram is as follow:

Hence, S is the grandson of T.

1) S is the son of Q.

2. Q is the daughter of R.

3) P is the daughter of T.

4. P and Q are siblings.

5. U is the father of S.

Using symbol table the family tree diagram is as follow:

As the gender of T and R is not clear, therefore father of Q can not be determined.

Hence, can not be determined is the correct answer.

**Given

Statement:

** X > Z < Y ≤ V; P > K > S = Q ≥ V 

On Combining: P > K > S = Q ≥ V ≥ Y > Z < X

Conclusion:

I) K > X → False ( As  K > S = Q ≥ V ≥ Y > Z < X → so, no direct relation between K and X can be determined)

II) Y < P → True ( As  P > K > S = Q ≥ V ≥ Y → so P > Y)

Hence, Only II is true.

**Given

Statements:

**  U ≤ W ≥ R > S ; T > S = V

on combining :   U ≤ W ≥ R > S = V < T

Conclusions:

I.  W < V → False  ( as W ≥ R > S = V ) it is clear that W is greater than V

II.  T < V → False  ( as S = V < T )   V is shorter than T

none of the conclusion follows therefore Neither I nor II is true

Confusion Points

both  statements not follow  the given  statement  as per statement  W ≥ R > S = V  it is clear W > V  while in conclusion it is given 

W < V  so it is false .

similarly  S = V < T → V < T  but in conclusion it is T < V so it is false

therefore  None is true

**Given

Statements:

** P ≥ Q = R ≥ N < S

Conclusions:

I) S > Q → False (as Q = R ≥ N < S → relation between S and Q cannot be determined)

II) P ≥ N → True (as P ≥ Q = R ≥ N → P ≥ N)

Hence, Only conclusion II follows.

Word: ABSOLUTE

The 2^nd, the 3^rd  and the 8^th letters of the word are B, S, and E respectively.

So, there is no meaningful word that can be made with the given letters.

Hence, "Y" is the correct answer.

Given: Eight people P, Q, R, S, T, U, V and W are sitting around a circle.

All of them are facing the center but not necessarily in the same order.

1. P is sitting to the second of T.

There will be two cases:

2. W is sitting third to the left of P. 3. U is sitting opposite W. 4. R is sitting opposite Q. 5. R is neighbour of neither W nor T. 6. V is not a neighbour of Q. 7. S is sitting next to the left of R. 

Here, case I will be cancelled out as no suitable place for V is left in case I.

So, the final arrangement will be:

Hence, T is sitting third to the right with respect to R.

So, the final arrangement will be:

Hence, 5 persons are sitting between Q and U.

The least possible Venn diagram for the given statements is:

Conclusions:

I. Some stars are sun. → False (No relationship is given between starts and sun, hence this condition is possible but not definite.)

II. Some planet are sun. → True (As it is given that 'only a few sun are planet.' some planets must be sun.)

Hence, only II follows.

The least possible Venn diagram for the given statements is:

Conclusions:

I. Some pens are scales. → False (No relationship is given between pens and scales, hence, it is possible but not definite.)

II. Some scales are pencil. → True (As all scales are pencil is true, some scales are pencil will also be true.)

Hence, only II follows.

The least possible Venn diagram for the given statements is:

Conclusions:

I. All lemons are banana. → False ( No specific information given about lemons and banana, hence, it is possible but not definite.)

II. Some lemons  are not banana. → False ( No specific information given about lemons and banana, hence, it is possible but not definite.)

Both of the above conclusions are following the conditions of 'either -or' pair.

Hence, either I or II follows.

Additional Information

 Conditions of Either-or case:

1. The elements should be the same in both the statements.
2. Both the conclusions should be false individually.
3. One conclusion should be positive and one conclusion should be negative (Complementary pair)

The two complementary pairs are:

1. All + Some not

2. No + Some

Note:

Some + Some not is not  considered under Either -or case.

The least possible Venn diagram for the given statements is:

Conclusions:

I. All rectangle being circle is a possibility. → True ( As nothing specific about rectangle and circle is given and none of the given statements is contradicting this possibility, hence the given possibility is true. The possibility diagram is shown below:

II. Some square are triangle. → True ( As some square are circle and all the circle are triangle, hence it is definitely true.)

Both follow.

The least possible Venn diagram based on the given statement is:

Conclusions:

I. Some tree are bird. → False (Nothing specific about tree and bird is given, hence this condition is possible but not definite.)

II. Some pigeon are bird. → False (Nothing specific about pigeon and bird is given, hence this condition is possible but not definite.)

Hence, none follows.
