Reasoning PYQs

Given: Nine persons- A, B, C, D, E, F, G, H, and I are born in different months January, March, April, June, July, August, September, November, and December of the same year but not necessarily in the same order.

1. C is born in a month having an even number of days.
2. D is born three persons after C.
3. The number of persons born before C is the same as after G.
4. Only one person is born between G and I. 

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

 

The number of persons born between C and I is the same as between A and B. B is born adjacent to G. A is born one of the months before B. 

Case 2a gets eliminated because there is no more space for A.

 

F is born in the just next month of E. H is not the eldest person. 

Case 2 gets eliminated because H is the eldest person. Hence, the final arrangement:

 

Except A, all are born in the months having 30 days.

Hence, the correct answer is ‘A’.

Given: Nine persons- A, B, C, D, E, F, G, H, and I are born in different months January, March, April, June, July, August, September, November, and December of the same year but not necessarily in the same order.

1. C is born in a month having an even number of days.
2. D is born three persons after C.
3. The number of persons born before C is the same as after G.
4. Only one person is born between G and I. 

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

 

The number of persons born between C and I is the same as between A and B. B is born adjacent to G. A is born one of the months before B. 

Case 2a gets eliminated because there is no more space for A.

 

F is born in the just next month of E. H is not the eldest person. 

Case 2 gets eliminated because H is the eldest person. Hence, the final arrangement:

 

H is born in December.

Hence, the correct answer is ‘December’.

Here, persons are E, H, K, O, P and V; shopping apps are Amazon, Allbirds, eBay, Flipkart, Nykaa and Purplle.

1. There is only one floor between H and the one who shops from Nykaa. 

2. P shops from Allbirds lives below the floor of H. Therefore, H lives on third floor.

3. O lives one of the floors below P but does not shops from Nykaa. Therefore, P lives on second floor.

 

4. The person who shops from Amazon lives to the northwest of V.

5. The person who shops from Flipkart does not live on an odd number floor.

6. The person shops from eBay lives above the floor of E but on different flats.

 

7. O lives to the southeast of K who does not shop from eBay. Therefore, case 1, 3 and 4 are eliminated.

Hence, the final arrangement is as follows

 

Hence, the incorrectly matched pair is E - Flipkart.

Here, persons are E, H, K, O, P and V; shopping apps are Amazon, Allbirds, eBay, Flipkart, Nykaa and Purplle.

1. There is only one floor between H and the one who shops from Nykaa. 

2. P shops from Allbirds lives below the floor of H. Therefore, H lives on third floor.

4. The person who shops from Amazon lives to the northwest of V.

5. The person who shops from Flipkart does not live on an odd number floor.

6. The person shops from eBay lives above the floor of E but on different flats.

 

7. O lives to the southeast of K who does not shop from eBay. Therefore, case 1, 3 and 4 are eliminated.

Hence, the final arrangement is as follows

 

Since, K and O who shops from Purplle lives on different flats. Therefore, statement first is incorrect.

P and V lives on second floor. Therefore, statement second is incorrect.

E who shops from Nykaa lives immediately below the floor of V but lives in different flats. Therefore, statement third is incorrect.

P who shops from Allbirds lives on Flat A of floor 2. Therefore, statement fourth is incorrect.

Hence, the correct answer is None of these.

Here, persons are E, H, K, O, P and V; shopping apps are Amazon, Allbirds, eBay, Flipkart, Nykaa and Purplle.

1. There is only one floor between H and the one who shops from Nykaa. 

2. P shops from Allbirds lives below the floor of H. Therefore, H lives on third floor.

4. The person who shops from Amazon lives to the northwest of V.

5. The person who shops from Flipkart does not live on an odd number floor.

6. The person shops from eBay lives above the floor of E but on different flats.

 

7. O lives to the southeast of K who does not shop from eBay. Therefore, case 1, 3 and 4 are eliminated.

Hence, the final arrangement is as follows

 

Since, each person except V lives on odd number floor whereas V lives on even number floor.

Hence, the odd one is V.

Here, persons are E, H, K, O, P and V; shopping apps are Amazon, Allbirds, eBay, Flipkart, Nykaa and Purplle.

1. There is only one floor between H and the one who shops from Nykaa. 

2. P shops from Allbirds lives below the floor of H. Therefore, H lives on third floor.

3. O lives one of the floors below P but does not shops from Nykaa. Therefore, P lives on second floor.

 

4. The person who shops from Amazon lives to the northwest of V.

5. The person who shops from Flipkart does not live on an odd number floor.

6. The person shops from eBay lives above the floor of E but on different flats.
