Reasoning PYQs

Given: Ten people— H, I, J, K, L, M, N, O, P, and Q —live in a building with five floors and two flats (Flat 1 and Flat 2) on each floor. The floors are numbered from 1 to 5 (1 being the lowermost floor and 5 being the topmost floor). Each floor has two flats viz., Flat-1 and Flat-2, where Flat 1 is to the west of Flat 2.  Flat 1 of floor 2 is immediately above Flat 1 of floor 1 and immediately below Flat 1 of floor 3 and so on. Similarly Flat 2 of floor 2 is immediately above Flat 2 of floor 1 and immediately below Flat 2 of floor 3 and so on. The area of each flat is equal.

Only two persons live on each floor and only one person lives in each flat.

1. H lives to the west of K.
2. K lives in Flat-2 of the topmost floor.
3. O lives on an even-numbered floor in Flat-1.
4. M lives west of J.
5. M lives on a floor immediately below the O’s floor. So, there are two cases here:

 

6. One floor between Q’s floor and O’s floor.
7. P and I live on the same named flat.
8. Only one floor is between P and L.
9. P lives below L.  

 

10. P and O lives in a different named flat.  
11. N lives immediately below L, but not in the same named flat. 

Case 1 gets eliminated here because there is no space left for M. So, the final arrangement is:

 

Three persons live between H and M in the same numbered flat.

Hence, the correct answer is ‘Three’.

Given Word: PLANET

1^st letter = P; 2^nd letter = L; 3^rd letter = A; 5^th letter = E

Letters given:  P L A E

Possible words: PALE (light in colour), LEAP (to jump), PEAL (a loud sound), PLEA (a request made in an urgent and emotional manner).

Hence, more than one such word can be made, and the answer is Y.

Given: Seven persons – A, B, C, D, E, F and G are working in the Indian army at different designations such as General, Brigadier, Colonel, Lt. Colonel, Major, Captain, and Subedar. The hierarchy of the designations is given in decreasing order such that General is the seniormost designation and Subedar is the juniormost designation.

All of them like different cities i.e., Indore, Delhi, Mumbai, Dehradun, Mumbai, Surat and Noida.

All the information given are not necessarily in the same order.

1. The one who likes Delhi is immediately junior to D, who is three designations senior to G, who is not the Subedar.
2. Only one person is designated between D and E, who is immediately junior to A.
3. Only three persons are designated between A and the one who likes Surat. 

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

 

4. The number of persons senior to E is one less than the number of persons designated between the one who likes Indore and Mumbai.
5. F is immediately junior to C and likes Dehradun. 

Case 1 is eliminated because F is immediately junior to C and likes Dehradun, which is not satisfied. 

 

6. The one who likes Mumbai is neither designated adjacent to the one who likes Indore nor designated adjacent to the one who likes Delhi.

The final arrangement is:

 

G is immediately senior to B.

Hence, the correct answer is ‘G’.
