Reasoning PYQs

Given: Six persons –C, P, Q, S, T and U – were born in different years among 1933, 1944, 1981, 1987, 1993 and 2018. The base year for calculating age is 2025. Each of them likes to visit a different place among Manali, Shimla, Goa, Munnar, Ooty, and Ladakh (not necessarily in the same order).

1. C is six years elder than the person who likes to visit Manali.
2. One person was born between the persons who likes to visit Manali and Ooty.
3. U is immediately elder than the person who likes to visit Ooty. So, there are two cases here:

 

4. S is two persons elder than T.
5. The one who likes to visit Goa is immediately younger than the T.
6. C doesn’t like to visit Goa. 

 

7. The one who likes to visit Ladakh is two persons elder than the one who likes to visit Munnar.

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

Conclusions:

I. All Strong is stupid. → False (it is possible but not definite)

II. Few fools are stupid. → False (it is possible but not definite)

III. All fools are stupid. → False (it is possible but not definite)

Hence, None conclusion follows

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

Conclusions:

I. Few IAS is IPS. → False (It is possible but not definite)

II. No IAS is IPS. → False (It is possible but not definite)

III. all ministers are women. → False (It is definitely false)

Conclusions I and II are complementary pair.

Hence, either conclusion I or II follows.

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

Conclusion:

I. All tables are chair → False (because only a few tables are chair)

II. All pen being tables is a possibility → False (As only books are pen so nothing else can be pen)

III. All chair are books is a possibility. → True ( As relation between Table and chair is of some also some table are not books. so in case of possibility except this some not part, Books can cover all the chair so it will be considered as true.)

Hence, only III follows.

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.
