Reasoning PYQs

The least possible Venn diagram for the given statements is:

Conclusions:

I. Some apples are fruit. → False ( As there is no definite relation between apples and fruit. Therefore this is possible but not definite)

II. Some fruits are bananas. → True (As it is given "Only a few fruits are bananas" therefore some fruits are bananas is true)

Hence, only 2 follows is the correct answer.

The least possible Venn diagram is as follows:

Conclusions:

I. Some pink are black. → True (As it is given  all black are pink this imply that some pink are black.)

II. Some red are pink. → False (As there is no definite relation between red and pink. Therefore this is possible but not definite).

Hence, only 1 follows.

The least possible Venn diagram for the given statements is:

Conclusions:

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

II. Some cats  are not animal. → False ( No specific information given about cats and animals, 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. Some chairs are bed → False (No definite positive or negative relation is given between the elements, so it is possible but not definite, therefore it is false)

II. Some furniture are tables → False (No definite positive or negative relation is given between the elements, so it is possible but not definite, therefore it is false)

Hence, Neither conclusion I nor II follows.

The least possible venn diagram for the given statements is

Conclusions:

I. Some mobiles being pens is a possibility → True (As no definite or negative relation is given between the elements, therefore it is possible)

II. Some pens are not scales → True (As the relation of “only a few” is given between the elements, which implies that “some” and “some not” both are true)

Hence, Both conclusion I and II follows.

Eight persons - A, B, C, D, E, F, G and H

Floor - 1 to 4, Flat - 1 and 2

1. There are two floor between B and C. B lives above C in the different flats. So here two possibilities for this.

 

2) A lives just west of D but on the odd number of floors. So, here remaining odd number floor is number 3. F lives just above C

 

3. No person lives west of G who lives on fourth floor.

In Case - II B lives on flat - 1 so G lives between flat - 2, So here B lives west of G. It contradict the given condition no person lives west of G so here Case - II gets cancelled. 

 

4. H does not live on floor number one. So H will live on floor number 2. There is only one place remaining for the E, on floor number 1.

 

Hence, H lives just east of F.

In Case - II B lives on flat - 1 so G lives between flat - 2, So here B lives west of G. It contradict the given condition no person lives west of G so here Case - II gets cancelled. 

 

4. H does not live on floor number one. So H will live on floor number 2. There is only one place remaining for the E, on floor number 1.

 

Hence, B lives on Fourth Floor.

In Case - II B lives on flat - 1 so G lives between flat - 2, So here B lives west of G. It contradict the given condition no person lives west of G so here Case - II gets cancelled. 

 

4. H does not live on floor number one. So H will live on floor number 2. There is only one place remaining for the E, on floor number 1.

 

Hence, E lives just below H.

Floor - 1 to 4, Flat - 1 and 2

1. There are two floor between B and C. B lives above C. So here two possibilities for this.

 

2) A lives just west of D but on odd number of floor. So, here remaining odd number floor is number 3. F lives just above C

 

3. No person lives west of G who lives on fourth floor.

In Case - II B lives on flat - 1 so G lives between flat - 2, So here B lives west of G. It contradict the given condition no person lives west of G so here Case - II gets cancelled. 

 

4. H does not live on floor number one. So H will live on floor number 2. There is only one place remaining for the E, on floor number 1.

 

Hence, Floor - 3 Flat - 2 - D is correct pair.

Hence, Floor - 1 Flat - 2 is correct combination.

Give Series: YXZ  BAC  JFG  ROP GON

When Changed to previous letter: XWY  AAB  IEF  QOO  FOM

Words having more than one vowel:  AAB  IEF  QOO

Hence, Three words have more than one vowel.

Give Series: YXZ  BAC  JFG  ROP GON

Second word form left end - BAC, Third letter - C 

Second word from right end - ROP, Second letter - O

 Hence, There are Eleven letters between C and O.

Give Series: YXZ  BAC  JFG  ROP GON

After interchanging the first and second letter of words:  XYZ  ABC  FJG  ORP  OGN 

Here words start with the vowel: ABC  ORP  OGN

Hence, Three words start with vowel.

Give Series: YXZ  BAC  JFG  ROP GON

Arrange in alphabetical order: XYZ  ABC  FGJ  OPR  GNO 

Here the fourth word From the left end is OPR, which forms from the word ROP.

Hence, the answer is ROP.

Give Series: YXZ  BAC  JFG  ROP GON

When we add 'E' in the last of each word: YXZE  BACE  JFGE  ROPE GONE

Here meaningful words are ROPE and GONE

Hence, two meaningful words will form.

The codes are as follows:

Hence, the code for 'computer' is 'fp'.

The codes are as follows:

Hence, the code for 'machine' is 'tq'.

The codes are as follows:

The code of 'he' can be 'pa' or 'za'

Hence, either 1 or 2 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, A sits at end of the row.

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, S sits second to the right of U.
