Reasoning PYQs

Given: Seven persons—A, B, C, D, E, F and G—live on different floors of a seven-floor building, numbered one to seven from bottom to top.

Each person likes a different fruit—Apple, Guava, Litchi, Watermelon, Mango, Kiwi and Grapes, but not necessarily in the same order.

1. Four floors are there between the floor on which E and the one who likes Mango lives.
2. E lives immediately below the one who likes Litchi.
3. The one who likes Litchi lives two floors above D. 

Here, there are two cases, i.e. Case 1 and case 2.

 

4. The number of floors below the floor of D is one less than the number of floors above the floor of the one who likes Grapes.
5. One floor is there between the floor of C and the one who likes Grapes.
6. C lives above the one who likes Apple.
7. D doesn’t like Apple. 

 

8. B lives two floors above G but doesn’t like Mango.
9. A lives three floors above the floor of the one who likes Kiwi. 
10. The one who likes Guava lives below the floor of the one who likes Kiwi.

Case 1 gets eliminated because there is no place for Guava. So, the final arrangement:

 

I. F likes Grapes - True

II. C lives below the floor on which the one who likes Mango lives - True

III. E lives immediately below D - False

Hence, the correct answer is ‘Only III’.

Given: Seven persons—A, B, C, D, E, F and G—live on different floors of a seven-floor building, numbered one to seven from bottom to top.

Each person likes a different fruit—Apple, Guava, Litchi, Watermelon, Mango, Kiwi and Grapes, but not necessarily in the same order.

1. Four floors are there between the floor on which E and the one who likes Mango lives.
2. E lives immediately below the one who likes Litchi.
3. The one who likes Litchi lives two floors above D. 

Here, there are two cases, i.e. Case 1 and case 2.

 

4. The number of floors below the floor of D is one less than the number of floors above the floor of the one who likes Grapes.
5. One floor is there between the floor of C and the one who likes Grapes.
6. C lives above the one who likes Apple.

8. B lives two floors above G but doesn’t like Mango.
9. A lives three floors above the floor of the one who likes Kiwi. 
10. The one who likes Guava lives below the floor of the one who likes Kiwi.

Case 1 gets eliminated because there is no place for Guava. So, the final arrangement:

 

C lives immediately below the floor on which the one who likes Watermelon lives.

Hence, the correct answer is ‘C’.

Given: Seven persons—A, B, C, D, E, F and G—live on different floors of a seven-floor building, numbered one to seven from bottom to top.

Each person likes a different fruit—Apple, Guava, Litchi, Watermelon, Mango, Kiwi and Grapes, but not necessarily in the same order.

1. Four floors are there between the floor on which E and the one who likes Mango lives.
2. E lives immediately below the one who likes Litchi.
3. The one who likes Litchi lives two floors above D. 

Here, there are two cases, i.e. Case 1 and case 2.

3. The one who likes Litchi lives two floors above D. 

Here, there are two cases, i.e. Case 1 and case 2.

 

4. The number of floors below the floor of D is one less than the number of floors above the floor of the one who likes Grapes.
5. One floor is there between the floor of C and the one who likes Grapes.
6. C lives above the one who likes Apple.
7. D doesn’t like Apple. 

 

8. B lives two floors above G but doesn’t like Mango.
9. A lives three floors above the floor of the one who likes Kiwi. 
10. The one who likes Guava lives below the floor of the one who likes Kiwi.

The one who likes Mango lives immediately above the floor on which F lives.

Hence, the correct answer is ‘The one who likes Mango’.

Odd numbers → Next digit

Even numbers → Previous digit

 

Replaced number: 2 7 4 6 1 8 5

Second digit from left end: 7

Third digit from right end: 1

Sum of both the numbers: 7 + 1 = 8

Hence, ‘8’ is the right answer.

Given: Eight persons—D, E, F, G, H, I, J, and K —sit in a linear row.

Some of them face North while some face South, but not necessarily in the same order. Number of persons facing south is more than the number of persons facing north.

1. E sits second to the left of D.
2. I sits fourth to the right of F.
3. F sits third to the left of D and face the same direction as D. 

Here, there are two cases, i.e. Case 1 and case 2. 4. J sits third to the left of I. 5. G sits fifth to the right of J. 6. Immediate neighbours of G face the same direction but opposite to G.

1. E sits second to the left of D.
2. I sits fourth to the right of F.
3. F sits third to the left of D and face the same direction as D. 

Here, there are two cases, i.e. Case 1 and case 2. 4. J sits third to the left of I. 5. G sits fifth to the right of J. 6. Immediate neighbours of G face the same direction but opposite to G. 

Case 1 gets eliminated because immediate neighbours of P face in the direction opposite to each other. 7. K sits immediate right of H. 8. Immediate neighbours of K face in the direction opposite to each other. So, the final arrangement is:

False statement - G faces south

Hence, the correct answer is ‘G faces south’.

Given: Eight persons—D, E, F, G, H, I, J, and K —sit in a linear row.
