Reasoning PYQs

Six Persons: H, I, J, K, L, and M.

1) Three people went on holiday between M and K.

2. M went after K.

 

3. Two people went on holiday between J and M.

4. H went on holiday immediately after L.

 

Only one position is left

 

5. I does not go in December.

Here, case 1 is invalid.

 

Hence, three persons went on holiday between H and I.

The best possible Venn diagram is,

Conclusions:

I. Some tablets are effective: False (No direct relation between tablets and effective, it is possible but not definite)

II. No effective is a tablets: False (No direct relation between effective and table, it is possible but not definite)

On complimentary conclusion I and II.

Hence, either conclusion I or II follows.

Key Points

Conditions for Either - Or 

1. Subject and predicate should be same
2. Both the individual conclusions should be false
3. One conclusion should be positive and one conclusion should be negative
4. There should either one of the following pairs present in the conclusions

• All + Some not
• Some + No

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

Conclusions: 

I. All A can be C → True  ( as there is no definite relation A and C is given, so its possibility is possible. hence, it is true) 

II. Some C is A  →  False  ( as there is no relation between A and C is given, it is possible but not definite. hence it is false)

Hence, Only I follow.

The least possible diagram is given below

Conclusion:

I. Some Salty is Pure → False (There is no definite relation between Salty and Pure but it is possible. So, it is false)

II. No Pure is Salty → False (There is no definite relation between Salty and Pure but it is possible. So, it is false)

Hence, Either I or II follows.

Points to remember:

There are only two complementary pairs for either - or case:

A. Some - No

B. All - Some not

Conditions for either - or:-

1. Both the conclusions must be individually false but not definitely false.
2. Conclusion should be Complementary Pair.
3. In the case of Some - No subject and predicate can interchange their positions.

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

Conclusions:

I. Some Ball being Red is a possibility → True (As there is no direct relation between Ball and Red some ball being red is possible but not definite. So, it is true)

II. Some Ball is Red → False (As there is no direct relation between Ball and Red it is possible but not definite. So, it is false)

Hence, Only I follow.

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

Conclusion:

I. No Walking is Jogging → False (There is no definite relation between Walking and Jogging. So, it is false)

II. Some Walking is Jogging → False (There is no definite relation between Walking and Jogging. So, it is false)

Hence, Either I or II follows.

Points to remember:

There are only two complementary pairs for either - or case:

A. Some - No

B. All - Some not

Conditions for either - or:-

1. Both the conclusions must be individually false but not definitely false.
2. Conclusion should be Complementary Pair.
3. In the case of Some - No subject and predicate can interchange their positions.

Persons: A, B, C, D, E, F and G

1) A is neighbor of B and C.

 

2) D is not neighbor of C or E.

3) G, who is second to the left of D, is the neighbor of E and F.

In case 1 the above condition is not satisfied in this case and thus eliminated.

The above arrangement will be final arrangement.

Hence, D sits second to left of A.

Persons: A, B, C, D, E, F and G

1) A is neighbor of B and C.

2) D is not neighbor of C or E.

3) G, who is second to the left of D, is the neighbor of E and F.

In case 1 the above condition is not satisfied in this case and thus eliminated.

The above arrangement will be final arrangement.

Thus, E is second to the left of F.

Persons: A, B, C, D, E, F and G

1) A is neighbor of B and C.

2) D is not neighbor of C or E.

3) G, who is second to the left of D, is the neighbor of E and F.

In case 1 the above condition is not satisfied in this case and thus eliminated.

The above arrangement will be final arrangement.

E is the neighbour of G and C.

Thus, "E is the neighbour of G and F" is the incorrect statement.

Persons: A, B, C, D, E, F and G

1) A is neighbor of B and C.

2) D is not neighbor of C or E.

3) G, who is second to the left of D, is the neighbor of E and F.

In case 1 the above condition is not satisfied in this case and thus eliminated.

The above arrangement will be final arrangement.

Thus, G sits third to right of A.

Persons: A, B, C, D, E, F and G

1) A is neighbor of B and C.

2) D is not neighbor of C or E.

3) G, who is second to the left of D, is the neighbor of E and F.

In case 1 the above condition is not satisfied in this case and thus eliminated.

The above arrangement will be final arrangement.

Thus, F is second to left of B.

Given Word: SOURCING

The given word can be represented as follows:

Thus, there are only 2 such pairs → Forward: SU; Backward: GI.

Hence, 2 is the correct answer.

The first, third, sixth and eighth letters of the word ‘ACCOUTERED are A, C, T and R.

A meaningful word from this is - CART

Hence, the correct answer is R.

Given series: 

LEFT END  L 4 B Δ W U S = 8 C N F 5 X T @ K O 1 Q V D β 6 A P E J R H + M Z  RIGHT END

Numbers that are immediately preceded by a symbol and immediately followed by a vowel:

LEFT END  L 4 B Δ W U S = 8 C N F 5 X T @ K O 1 Q V D β 6 A P E J R H + M Z  RIGHT END

Clearly, only 6 is immediately preceded by a symbol and also immediately followed by a vowel.

Hence, 1 is the correct answer.

Given Series: L 4 B Δ W U S = 8 C N F 5 X T @ K O 1 Q V D β 6 A P E J R H + M Z

In each group, the pattern follows as:

The second element is second to the left of the first element.

The third element is third to the right of the second element.

Also in the series,

the first element of the second group (i.e. U of UΔS) is the immediate right of the third element of the first group (i.e. W of Δ4W)

LEFT END  L 4 B Δ W U S = 8 C N F 5 X T @ K O 1 Q V D β 6 A P E J R H + M Z  RIGHT END

By following the above pattern we get FC5.

Hence, FC5 is the correct answer.

Given series: 

LEFT END  L 4 B Δ W U S = 8 C N F 5 X T @ K O 1 Q V D β 6 A P E J R H + M Z   RIGHT END

Clearly, there is no such consonant that is immediately preceded by a symbol and followed by a number.

Hence, 0 is the correct answer.
