Reasoning PYQs

Family Chart:

As per the given information

Since we don't know the gender of 'C'.

So, we cannot determine how 'C' is related to 'A'

Hence, the correct answer is "Option 4"

The logic follows here,

• 1331 = 113113 11^3
• 2197 = 133133 13^3
• 3375 = 153153 15^3
• 4096 = 163163 16^3
• 1331, 2197, 3375 are cubes of odd numbers
• 4096 is the cube of an even number
• Hence, the correct answer is "Option 3"

The logic follows here, 

Thus, it should be 41 instead of 40.

Hence, the correct answer is "Option 3"

The logic followed here is:

MOUSE is coded as 45291

And,

RAT as 786

Similarly,

STORE is coded as

Hence, the correct answer is "Option 1"

The logic followed here is,

Logic: x $ y = x² + y²

Now,

→ 7 $ 3:

7² + 3² = 49 + 9 = 58 (Matches)

→ 6 $ 2:

6² + 2² = 36 + 4 = 40

Similarly, for 5 $ 1

→ 5² + 1² = 25 + 1 = 26.

Hence, the correct answer is "Option 1".

Decoding symbols for Family Tree:

Step-by-step Relationship Analysis:

Breakdown the statement made by the woman: "She is the daughter of my mother's only daughter."

• "My mother's only daughter" – Since the speaker is a woman, her mother's only daughter is the woman herself.
• Now, replace that part in the sentence: "She is the daughter of "me" (the woman)."

Consolidated Family Structure:

Thus, the girl is the Daughter of the woman.

Hence, the correct answer is "Option 1"

Decoding symbols for Family Tree:

Step-by-step Relationship Analysis:

Breakdown the statement: "This man's son's sister is my daughter."

• "This man's son's sister" – A son's sister is simply the man's Daughter.
• If the same girl is the daughter of the man AND the daughter of the woman, then the man and the woman must be the parents of that girl.

Consolidated Family Structure:

Thus, the woman is the Wife of the man.

Hence, the correct answer is "Option 1"

Shortcut Trick

Total units in the ratio = 7 + 9 = 16 units.

Given Sum = 128, so 16 units = 128 → 1 unit = 128 ÷ 16 = 8.

First number = 7 × 8 = 56.

Second number = 9 × 8 = 72.

∴ The correct answer is 56, 72.

Alternate Method

Given: Ratio of two numbers = 7 : 9 and Sum of numbers = 128.

Formula Used: If a sum S is divided in the ratio a : b, then the parts are (a / (a + b)) × S and (b / (a + b)) × S.

⇒ Let the two numbers be 7x and 9x.

⇒ According to the question, 7x + 9x = 128

⇒ 16x = 128

⇒ x = 128 ÷ 16

⇒ x = 8

⇒ First Number = 7 × 8 = 56

⇒ Second Number = 9 × 8 = 72

∴ The correct answer is 56, 72.

Additional Information

Ratio Definition

A ratio is a comparison of two or more quantities of the same kind by division. For a : b, 'a' is called the antecedent and 'b' is the consequent.

Inverse Ratio

The inverse ratio of a : b is b : a. This is commonly used in speed-time and work-efficiency problems.

Compounded Ratio

For two ratios a : b and c : d, the compounded ratio is (a × c) : (b × d).

Proportion

When two ratios are equal, they are said to be in proportion (a : b :: c : d), implying the product of extremes equals the product of means (ad = bc).

Given:

If 16 + 11 = A and (1)/(9)=B, A % B = (A×B)-1, then find A % B.

Formula used:

A % B = (A×B) - 1

Calculations:

A = 16 + 11 = 27

B = 1/9

A % B = (A×B) - 1

⇒ A % B = (27×1/9) - 1

⇒ A % B = 3 - 1

⇒ A % B = 2

∴ The correct answer is option (3).

Given:

Sum of 28 and 22 = 28 + 22

Multiplier = 8

Formula used:

Total = (Sum) × Multiplier

Calculation:

⇒ Total = (28 + 22) × 8

⇒ Total = 50 × 8

⇒ Total = 400

∴ The correct answer is option (2).

The logic followed here is:

So, 'QUY' will replace the question mark in the given series.

Hence, the correct answer is "Option 1".

The logic followed here is:

So, 'QAK' will replace the question mark in the given series.

Hence, the correct answer is "Option 3".

The logic followed here is:

thus, "182" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

Logic: Next term = (Previous term)² + 1

thus, "458330" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is:

thus, "26" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

Given Statement: While the world is moving towards automation, it is essential to ensure that ethical frameworks evolve alongside technological advancements to prevent misuse.

Now, 

Assumptions:

I. Automation can lead to ethical dilemmas - Implicit (If there were no ethical risks, there would be no need to evolve ethical frameworks to prevent misuse)

II. Ethical frameworks must be updated to keep pace with technological advancements - Implicit  (The statement directly argues that ethical frameworks should evolve alongside technology.)

III. Automation will eventually replace human labor in all sectors - Not Implicit (The statement only discusses automation increasing, not complete replacement of human labor.)

Here, Only I and II are implicit

Hence, the correct answer is "Option 1".

Given word: 'DEVELOP'

After arranged in alphabetical order:

 

After arranged in alphabetical order: D, E, E, L, O, P, V

Thus,Two letters remain in the same position.

Hence, the correct answer is "Option 1".

The address given in the problem is,

No. 45, First Avenue, Raja Annamalaipuram, Chennai, Tamil Nadu - 600028

Let's match this address with the given options one by one to figure out which one is exactly the same.

 

So, the address that is exactly the same as the given address is in option (2).

Hence, the correct option is "option (2)".

Let’s check each option,

1) CANCEL → cannot be formed as there is  No A in INTELLIGENCE.

2) NEGLECT→ can be formed as INTELLIGENCE

3) GENTLE → can be formed as INTELLIGENCE

4) INCITE → can be formed as  INTELLIGENCE

Hence, “CANCEL” can’t be formed.

Hence, the correct answer is "option (1)".

Given: Eight persons A, B, C, D, E, F, G, and H are sitting around a circle facing the center.

1.C is second to the right of A.

2.E is opposite C.

3.F is to the immediate left of E.

4.B is to the immediate right of A.

5.G is to the immediate left of D.

Thus, F is sitting to the right of D.

Hence, the correct answer is "Option 4".
