Reasoning PYQs

Consider the series:

S 4 5 4 S S 4 5 4 S 7 S W 7 5 7 5 W 4 4 4 W C C 5 5 7 C C 7

Total number of C → 4

Total number of S → 5

Total number of 4 → 7

Total number of 5 → 6

Total number of W → 3

Hence, W has the lowest frequency.

Consider the following series: _____

S 4 5 4 S S 4 5 4 S 7 S W 7 5 7 5 W 4 4 4 W C C 5 5 7 C C 7

Numbers are 454, 454, 757, 575, 444

Hence, five is the correct answer.

Consider the following series:

S 4 5 4 S S 4 5 4 S 7 S W 7 5 7 5 W 4 4 4 W C C 5 5 7 C C 7

Hence, according to the above series, three consecutive repeated pairs are there: SS, CC, CC 

Hence three is the correct answer.

Consider the given series:

S 4 5 4 S S 4 5 4 S 7 S W 7 5 7 5 W 4 4 4 W C C 5 5 7 C C 7

Hence, five numbers are there which are immediately preceded by 5:- 54, 54, 57, 55, 57

Hence, five is the correct answer.

The given word MACHINE and its positional value given in the table and its pairs in backward and forward directions:

Forward pairs (Left to Right): HI

Backward pairs (Right to Left): IM, EH

There are three pairs in both Backward and Forward direction.

Hence, three is the correct answer.

Note:

I. Only few feasts are vultures.

This implies that

All feasts are not vultures.

Some feasts are vultures.

Some feasts are not vultures.

II. Only feasts are cards.

The above statement implies that

All cards are feasts.

No card is vulture.

No card is veg.

The least possible Venn diagram is given below

Conclusions:

I. Some veg are feasts.→ False (it is possible but not definite)

II. Some feasts are cards. → True (as only feasts are cards)

Hence, only conclusion II follows.

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

Conclusions:

I. Some roses are smell → False (It is possible but not definite)

II. No roses are smell → False (It is possible but not definite)

Conclusion I and II forms complementary pair.

Thus, either conclusion I or conclusion II follow.

Note:

I. None of the fumes are volcano.

The above statement implies that

No fume is volcano.

II. A few volcanoes are active.

The above statement implies that

Some volcanoes are active.

The least possible Venn diagram is given below

Conclusions:

I. Some volcanoes are violent. → True (those volcanoes that are active are also violent)

II. Some active are not fumes.→ True (those active that are volcanoes are not fumes)

Hence, both the conclusion I and II follow.

Note:

I. Only Ds are Fi.

The above statement implies that

All Fi are Ds.

No Fi is Qw.

No Fi is Cv.

III. Few Cv are Qw.

The above statement implies that

Some Cv are Qw.

The least possible Venn diagram is given below

Conclusions:

I. No Ds is Qw. → False (as Some Qw are Cv and All Cv are Ds)

II. All Fi are Qw.→ False (as only Ds are Fi.)

Hence, none of the conclusion follows.

The least possible Venn Diagram for the given statements will be as follows,

I. No Mango is Grape → True (As all mango is banana and no banana is grape, so no mango is grape.)

II. Some Kiwi is Mango → True (This is definitely true)

Hence, ‘Both I and II follows’ is the correct answer.

2. D sits fifth from the left end.

 

3. There are more than two persons between F and D.

Given numbers: 378 256 431 875 762

On adding 2 to the second digit: 398 276 451 895 782

On arranging the numbers in descending order: 895 782 451 398 276

451 is the third-lowest number and the corresponding number of that in the actual series is 431

Hence, 451 is the third lowest number which is obtained from 431.

Given numbers: 378 256 431 875 762

Sum of first and second digits,

762 = 7 + 6 = 13

378 = 3 + 7 = 10

256 = 2 + 5 = 7

431 = 4 + 3 = 7

875 = 8 + 7 = 15

Hence, 15 is more than 13 which is obtained from 875.

Given numbers: 378 256 431 875 762

On subtracting 1 from each number: 377 255 430 874 761

Hence, two numbers i.e., 255 and 430 are divisible by 5.

Given numbers: 378 256 431 875 762

On subtracting first and third digits,

378 = 8 – 3 = 5

256 = 6 – 2 = 4

431 = 4 – 1 = 3

875 = 8 – 5 = 3

762 = 7 – 2 = 5

Hence, 4 is the second highest resultant which is obtained from 256.

Eight people A, B, C, D, J, K, L and M

1) C sits second to the right of L.

 

 

2) Only one person sits between C and M when counted from the right of C.

3) A is not an immediate neighbor of M. B faces D who sits immediately to the left of K.

 

4) K sits at one of the corners.

Therefore, case 1 gets eliminated.

Thus, the final arrangement is:

Hence, K sits third to the left of J.

Eight people A, B, C, D, J, K, L and M

1) C sits second to the right of L.

 

 

2) Only one person sits between C and M when counted from the right of C.

 

3) A is not an immediate neighbor of M. B faces D who sits immediately to the left of K.

 

4) K sits at one of the corners.

Therefore, case 1 gets eliminated.

Thus, the final arrangement is:

​

 

There are 4 people between C and D when counted clockwise from D.

Hence, "More than three" is the correct answer.
