Reasoning PYQs

Given: 

Kiran walks 7 km south, then turns to her right and walks 4 km.

She again turns to her right and walks 7 km.

Movement of Kiran is,

So, she is 4km from her starting point.

Hence, the correct answer is "Option 4".

The logic followed here is,

Logic: A backward shift of 3 positions.

Relationship between 'X' and 'U':

Applying the same logic to 'N':

Thus, 'N' is to 'K'.

Hence, the correct answer is "Option 1".

Given: 

Rohan walks 10 meters towards the North.

Then he turns right and walks 5 meters.

Again, he turns right and walks 10 meters. 

Movement of Rohan is,

So he is in East direction from his starting point.

Hence, the correct answer is "Option 3".

The logic followed here is:

Thus, the missing term in the series is 81.

Hence, the correct answer is "Option 4".

Given:

Number of workers (W1 ) = 6

Days to complete the job (D1) = 15 days

Number of new workers (W2) = 9

Formula used:

W₁ × D₁ = W₂ × D₂

Where, D₂ is the number of days taken by the new workers

Calculation:

6 × 15 = 9 × D₂

⇒ 90 = 9 × D₂

⇒ \(\dfrac{90}{9}\) = D₂

⇒ D₂ = 10

The correct answer is option (1).

Given:

Length of the train (L) = 150 m

Time taken to pass the pole (T) = 10 s

Formula used:

Speed = \(\frac{Distance}{Time}\)

Note:

When a train passes a pole, the distance covered is equal to the length of the train.

To convert m/s to km/h, multiply by \(\frac{18}{5}\).

Calculations:

Speed in m/s = \(\dfrac{150}{10} \)

⇒ Speed = 15 m/s

Now, convert the speed to km/h:

Speed in km/h = 15 × \(\frac{18}{5}\)

⇒ Speed in km/h = 3 × 18

⇒ Speed in km/h = 54

∴ The correct answer is option (2).

Logic applied for the input:

Apple 41 Orange 62 85 Mango Banana 19

The rearrangement rule is to move the "alphabetically smallest word" to the leftmost side and the "numerically largest number" to the rightmost side in each step.

This process continues until all words are at the left, sorted alphabetically, and all numbers are at the right, sorted in descending order.

Input: Apple 41 Orange 62 85 Mango Banana 19

Step 1: Find the alphabetically smallest word (Apple) and the numerically largest number (85).

Apple Banana 41 Orange 62 Mango 19 85

Step 2: Find the next smallest word (Banana) and the next largest number (62).

Apple Banana 41 Orange Mango 19 85 62

Step 3: Find the next smallest word (Mango) and the next largest number (41).

Apple Banana Mango Orange 19 62 85 41

Step 4: Find the last word (Orange) and the last number (19).

Apple Banana Mango Orange 62 85 41 19 

The final arrangement, with all words arranged in alphabetical order at the left end, and all numbers in descending order at the right end, is "Apple Banana Mango Orange 62 85 41 19".

Hence, the correct answer is "Option 1".

The first statement, "All birds fly," is the premise.

This premise is factually incorrect because there are many birds, such as penguins and ostriches, that do not fly.

Since the initial premise is false, the conclusion derived from it is not logically sound, even though the argument's structure (a syllogism) is valid in form.

The conclusion that "penguins fly" is factually incorrect because it is based on a false starting point.

The flaw in the argument "All birds fly. Penguins are birds. Therefore, penguins fly." is a false premise.

Hence, the correct answer is "Option 4".

Here is an explanation of each option:

Option 1) Talking calmly to resolve it: This is an effective and mature way to handle conflict. It shows a desire to understand the other person's perspective and find a solution that works for both of you.

Option 2) Ignoring the friend permanently: This action is a form of passive aggression and shows poor judgment. It avoids the issue entirely, prevents any possibility of resolution, and causes long-term damage to the friendship. It demonstrates a lack of respect for the friend and the relationship.

Option 3) Taking time to cool off: This is a very wise and helpful action. It prevents you from saying or doing something hurtful in the heat of the moment and allows both parties to approach the conversation with a clearer mind.

Option 4) Writing a letter to express your feelings: This can be a constructive way to communicate, especially if you find it difficult to express yourself verbally in a calm manner. It allows you to organize your thoughts and feelings clearly without interruption, and it gives your friend time to process what you've said before responding.

The action that shows poor judgment in handling a disagreement with a friend is Option 2) Ignoring the friend permanently.

Hence, the correct answer is "Option 2".

Given:

Number of workers (W₁) = 4

Days to complete the job (D₁) = 12 days

Number of new workers (W₂) = 6

Formula used:

W1 × D1 = W2 × D₂

Where, D₂ is the number of days taken by the new workers

Calculation:

4 × 12 = 6 × D₂

⇒ 48 = 6 × D₂

⇒ \(\dfrac{48}{6}\) = D₂

⇒ D₂ = 8

The correct answer is option (1).

The logic followed here is that all the numbers except one are perfect squares.

121 = 11²

169 = 13²

144 = 12²

The number 189 is not a perfect square as it cannot be expressed as an integer squared.

Hence, the correct answer is "Option 2".

The logic followed here is:

Therefore, the wrong term in the given series is 86, which should be 85.

Hence, the correct answer is "Option 2".

Decoding symbols for Family Tree:

Let's decode the relationships step-by-step:

A and B are sisters. 

C is the brother of A. This means A, B, and C are all siblings.

D is the father of C. Since A, B, and C are siblings, D is the father of all three of them.

According to the given information Family Tree Representation:

Now, let's determine how D is related to B:

Thus, D is the Father of B.

Hence, the correct answer is "Option 1"

The logic followed here is:

We can find the rank from the bottom using the following formula:

Rank from the bottom = (Total number of students) - (Rank from the top) + 1

Given:

Total number of students = 41

Ramesh's rank from the top = 21^st

Applying the formula:

Rank from the bottom = 41 - 21 + 1

= 20 + 1 = 21

So, Ramesh's rank from the bottom is 21^st.

Hence, the correct answer is "Option 2".

The logic followed here is a consistent +1 shift in alphabetical position for each letter.

1. SMILE : TNKLI

SMILE: TNKLI is the only one with inconsistent shifts, so it does not belong to the group.

2. BRING: CSJOH
3. FLOUR: GMPVS
4. HOUSE: IPVTF
5. TRUTH: USVUI

Therefore, SMILE : TNKLI is the one that does not belong to the group.

Hence, the correct answer is "Option 4".

Given:

Number of workers (W₁) = 4

Days to complete the job (D₁) = 8 days

Number of new workers (W₂) = 8

Formula used:

W₁ × D₁ = W₂ × D₂

Where, D₂ is the number of days taken by the new workers

Calculation:

4 × 8 = 8 × D₂

⇒ 32 = 8 × D₂

⇒ \(\dfrac{32}{8}\) = D₂

⇒ D₂ = 4

The correct answer is 4 days.

The logic followed here is,

LIGHT : MJGHW

HEAVY : ?

The final coded word is IFAVB.

Hence, the correct answer is "Option 1".

The logic followed here is:

Thus, the missing term in the series is 126.

Hence, the correct answer is "Option 4".

The logic followed here is:

Thus, the missing term in the series is 27.

Hence, the correct answer is "Option 2".

Given

Statements:

No humans are immortal.

Some humans are scientists.

The least possible Venn diagram for the given statements is:

Conclusions:

I. All humans are immortal. → False (This directly contradicts the first statement, "No humans are immortal.")

II. All scientists are mortal. → False (The statements do not provide enough information to definitively conclude that all scientists are mortal. So we do not say that "All scientists are mortal".)

III. Some scientists are not immortal. → True (Since "No humans are immortal" and "Some humans are scientists," it logically follows that the group of scientists who are humans must not be immortal. This is a definite conclusion.)

IV. Some scientists are not humans. → False (The statements only confirm that some scientists are humans, not that any are non-human. This conclusion cannot be drawn.)

So, only conclusion III follows.

Hence, the correct answer is "Option 3".
