Reasoning PYQs

Eight people A, B, C, D, J, K, L and M

1) C sits second to the right of L.

 

2) Only one person sits between C and M when counted from the right of C.

 

3) A is not an immediate neighbor of M. B faces D who sits immediately to the left of K.

 

4) K sits at one of the corners.

Therefore, case 1 gets eliminated.

Thus, the final arrangement is:

​

C, K, L, M are sitting at the corners of the table whereas B is sitting at the middle of one of the sides.

Hence, B does not belong to the group.

Eight people A, B, C, D, J, K, L and M

1) C sits second to the right of L.

 

2) Only one person sits between C and M when counted from the right of C.

 

3) A is not an immediate neighbor of M. B faces D who sits immediately to the left of K.

 

4) K sits at one of the corners.

Therefore, case 1 gets eliminated.

Thus, the final arrangement is:

​

 

1) A sits immediate right of K. - True

2) A sits second to the right of B - True

3) A is an immediate neighbor of C - False (B and J are immediate neighbours of C)

Hence, "Both 1 and 2" is the correct answer.

Eight people A, B, C, D, J, K, L and M

1) C sits second to the right of L.

 

 

2) Only one person sits between C and M when counted from the right of C.

 

3) A is not an immediate neighbor of M. B faces D who sits immediately to the left of K.

 

4) K sits at one of the corners.

Therefore, case 1 gets eliminated.

Thus, the final arrangement is:

​

 

M sits immediate right of D.

K sits second to the right of M.

Hence, K is the correct answer.

Given names: A, B, C, D, E, F, and G.

1. B is the second lightest person.

2. The one who is the lightest person has 65 kg of weight.

3. Three persons have their weight between B and G.

4. F is the heaviest of all.

5. D has an equal number of persons who are heavier and lighter than him.

(Hence, D will be in the middle of the arrangement).

6. D has a weight of 85 kgs.

7. E is just heavier than B.

8. A is heavier than C.

Hence the final arrangement will be as follows:

 

Weight of D = 85 kg

Weight of C = 65 kg

Average weight = (85 + 65) / 2 = 150 / 2 = 75

Hence, the average weight of D and C is 75 kg.

Given names: A, B, C, D, E, F, and G.

1. B is the second lightest person.

2. The one who is the lightest person has 65 kg of weight.

3. Three persons have their weight between B and G.

4. F is the heaviest of all.

5. D has an equal number of persons who are heavier and lighter than him.

(Hence, D will be in the middle of the arrangement).

6. D has a weight of 85 kgs.

7. E is just heavier than B.

8. A is heavier than C.

Hence the final arrangement will be as follows:

The weight of E should be between the weight of D (85) and C (65).

Hence, 76 kg is the possible weight of E.

Given

Statements:

D > F ≥ G ≥ H; H ≥ I = J

On combining: D > F ≥ G ≥ H ≥ I = J

Conclusions:

I. J = F → False (as F ≥ G ≥ H ≥ I = J → J ≤ F)

II. F > J → False (as F ≥ G ≥ H ≥ I = J → F ≥ J)

Therefore, conclusion I and II forms a complementary pair.

Hence, Either I or II is True.

Given

Statements:

L = G ≥ H = N; C > K ≥ Q = N

Combined

Statement:

L = G ≥ H = N = Q ≤ K < C

Conclusions:

K ≥ L → False → as L = G ≥ H = N = Q ≤ K < C → thus clear relation between K and L cannot be determined)

C ≥ G → False → as L = G ≥ H = N = Q ≤ K < C → thus clear relation between C and G cannot be determined)

Hence, Neither I and II is True

Given

Statements:

P > Q = V; V < T

On combining: P > Q = V < T

I. Q = T → False (as Q = V < T → Q < T)

II. T > P → False (as direct relation between T and P can’t be determined)

Both conclusions are false, hence, neither is true.

Given

Statement:

J < G ≥ L > N < K ≤ F < T = H

Conclusion:

I. F > L → False (as L > N < K ≤ F) thus clear relation between F and L cannot be determined as symbols are in reverse order.

II. K < H → True (as K ≤ F → F < T → T = H → So, K < H)

Therefore, only conclusion II follows.

Given

Statements:

A < B = C > D, D ≥ F ≥ E

Conclusions:

I. B > E → True [B = C > D ≥ F ≥ E, Hence, B > E]

II. C > A → True[AS C = B > A]

Hence, bothI& II are True.

The least possible Venn diagram for the given statements is as follows,

I. Some N are E → True( It is definite )

II. Some E are not D → True( because given only a few E are D. it means some E are definitely D and some E are not definitely D )

Hence, Both conclusions I and II follow.

 Only few = some + Some not

Only few A are B means 'Some A are B' as well as 'Some A are not B'.

The least possible Venn diagram for the given statements is as follows,

I. Some tree is leaf → False (It can be possible, but it is not definite)

II. Some plant is tree → True (It is definite)

Hence, only conclusion II follows.

The least possible Venn diagram for the given statements is as follow:

Conclusions:

I. Some wood is table → False (it is possible but not definite.)

II. Some tables being wood is a possibility → True (it is possible.)

Thus, only conclusion II follows.

The least possible Venn diagram for the given statements is as follow:

Conclusions:

I. No fruit being plant is a possibility → False (it is not possible.)

II. Some fruits are plants → True (it is definite.)

Thus, only conclusion II follows.

The least possible Venn Diagram for the given statements will be as follows,

I. Some Soap are Conditioner → True (As some soap are shampoo and all shampoo are conditioner, some soap is definitely conditioner.)

II. No Soap is Conditioner → False (Some soap is definitely conditioner)

Hence, ‘Only I follows’ is the correct answer.
