Reasoning PYQs

Given:

R ≥ T = Q < M; S ≥ R

On Combining:

S ≥ R ≥ T = Q < M

Conclusions:

I. M < R → False (as R ≥ T = Q < M; therefore,the relationship between M and R cannot be determined)

II. S ≥ Q → True (as S ≥ R ≥ T = Q; therefore S ≥ Q)

Hence, only conclusion II is true.

Given

Statements:

M > N < O ≤ P; S ≥ R > Q = P

On combining: M > N < O < P = Q < R ≤ S

I. S ≥ M → False (as M > N < O < P = Q < R ≤ S) thus clear relation between S and M cannot be determined.

II. S < M → False (as M > N < O < P = Q < R ≤ S) thus clear relation between S and M cannot be determined.

A number can be either equal, less, or greater than another number.

Here, S ≥ M (S is greater than or equal to M).

S < M (S is smaller than M).

One statement must be true but can't say which statement.

Hence, Either I or II follows.

Given

Statements:

A > B, D ≤ E, D ≥ C ≤ B

On combining: A > B ≥ C ≤ D ≤ E

Conclusions:

I. C < A → True (as A > B ≥ C → A > C)

II. E ≥ C → True (as C ≤ D ≤ E → C ≤ E)

Hence, both I and II are true

Six persons: P, Q, R, S, T and U

Floors: 1, 2, and 3

Flat: X and Y

(1) P lives on an odd numbered floor in flat X. Therefore, we get two the following two cases here.

 

(2) The one who is from Kolkata lives immediately above U  in the same flat. . (3) S lives to the west of U. (4) P and the one who is from Kolkata do not live on the same floor.

 

(5) T does not live in flat Y. (6) There is one floor between Q and the one who is from Delhi who lives above Q. Since, only flat Y of floor 3 is left for Q in case (I), case (I) eliminates here.

 

(7) Neither S nor Q is from Bangalore. (8) U is either from Pune or from Agra (implies, P is from Bangalore). (9) The one who is from Mumbai lives on the same floor on which the one who is from Agra lives (implies, S is from Mumbai and U is from Agra). Thus, the final arrangement is as follows:

 

We can see that, all T, R, P, and Q live in odd numbered floor and thus forms a group.

Hence, S does not belong to that group.

Hence, Q lives in Flat - Y.

Given: 621754

By adding 2 in the even digits and subtracting 1 from the odd digits, we will get,

Here can clearly says that 8 and 0 are not repeated.

Therefore, sum of the number = 8 + 0 = 8

Hence, "8" is the correct answer.

Given word: LAVISLY

After replacing each vowel with the next letter in the alphabetical series and each consonant with the previous letter in the Alphabetical Series, we get:

 

Here, one letter, K occurred twice.

Hence, one is the correct answer.

The least possible Venn diagram is:

Conclusions:

I. All Glass are Plate → False (This is possible but not definite, as no direct relationship between the two is given).

II. Some Cup are not Bottles → True (As, Only Plate is Bottle is given which means All Bottles are Plate and Bottles will not have any positive relationship with any other element except with Plates, so Some Cups are not Bottles is true).

III. Some Cup are not Plates → True (As, Only a few Cup are Plates is given, which means Some Cup are Plates and Some Cups are not Plates, so this is definitely true).

Hence, Both Conclusion II and III follows.

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

Conclusion:

I. No grass is tree → True

II. Some green are plant → True

Hence, both I and II follow.

The least possible diagram is as follows:

Conclusions:

I. Some flowers are stem. → False (As there is no direct relation between flowers and stem. So, some flowers are stem is false.)

II. No petal is flowers. → True (As the relation of flowers is only limited to leaves. So, no petal is flowers is true.)

Hence, only conclusion II is true.

Mistake Points Only A are B’ means that B can not be linked positively with any other object.

The least possible Venn diagrams as follows,

Conclusion:

I. Some nail is poly → False (because only toe can be poly)

II. Some finger is toe → False (because only nails can be toe)

Hence neither I nor II conclusion follow.

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

Conclusion:

I. No black is good → False (It is possible but not definite)

II. No green is bad → False (It is possible but not definite)

III. Some black are good → False (It is possible but not definite)

Conclusion I and III forms complementary pair.

Thus, either conclusion I or conclusion III follow.
