Reasoning PYQs

Statement: All oranges are fruits. No fruit is a vegetable. All vegetables are green.

The least possible Venn diagram for the given statement is:

Conclusions:

I. No orange is green. - False (No orange being green is a possibility, but it is not definite. So, the conclusion is false)

II. No orange is a vegetable. - True (All orange being fruit is not a vegetable as No fruit is a vegetable)

Hence, the correct answer is "Option 2".

Given word: Hollowness

Let's check each option:

1. Hole → Hollowness → Can be formed 2. whale → Hollowness → Cannot be formed as "a" is missing. 3. Hang → Hollowness → Cannot be formed as "a" and "g" are missing. 4. HUng → Hollowness → Cannot be formed as "u" and "g" are missing.

so, Hole can be formed from the letters of the given word.

Hence, the correct answer is "Option 1".

The position and positional values or English Alphabets are:

 

Given series: AB, BC, CD, DE, ?

 

The logic followed here is:

So, EF comes next.

Hence, the correct answer is "Option 4".

The position and positional values or English Alphabets are:

The logic followed here is:

Similarly,

So, SUGAR is written as RTFZQ.

Hence, the correct answer is "Option 1".

The logic followed here is:

1. Balance of Trade → Economic concept (difference between exports and imports of goods)

2. Balance of Payments → Economic concept (record of all international transactions)

3. Current Account Deficit → Economic concept (when imports + outflows exceed exports + inflows)

4. Food Security Act → Government legislation/law

All options except "Food Security Act" are economic/financial terms, while Food Security Act is a law/policy.

Hence, the correct answer is "Option 4".

Given: As a judge, you notice a lawyer influencing a witness. 

1. Ignore unless it repeats

Ignoring such behavior is inappropriate because influencing a witness directly affects the fairness of the trial and the integrity of the judicial process.

2. Hold the lawyer in contempt

This is the correct action. Influencing a witness is professional misconduct and obstruction of justice. A judge has the authority to hold the lawyer in contempt of court to maintain fairness and discipline in proceedings.

3. Adjourn the case permanently

Permanently adjourning the case is not a proper response. The issue should be addressed by disciplinary action against the lawyer, not by stopping the case entirely.

4. Request the witness to stay silent

Silencing the witness does not solve the problem. The correct step is to address the lawyer’s misconduct, not restrict the witness.

Hence, the correct answer is "Option 2".

Given equation: 8 × 3 + 4 = 28

BODMAS Table:

Let's check each option one by one.

1. + and ×, 3 and 4

Given: 8 × 3 + 4 = 28

After interchanging the signs and numbers we get;

⇒ 8 + 4 × 3 = 28

⇒ 8 + 12 = 28

⇒ 20 ≠ 28

⇒ LHS ≠ RHS

2. • and ×, 8 and 3

Given: 8 × 3 + 4 = 28

After interchanging the signs and numbers we get;

⇒ 3 + 8 × 4 = 28

⇒ 3 + 32 = 28

⇒ 35 ≠ 28

⇒ LHS ≠ RHS

3. • and ×, 8 and 4

Given: 8 × 3 + 4 = 28

After interchanging the signs and numbers we get;

⇒ 4 + 3 × 8 = 28

⇒ 4 + 24 = 28

⇒ 28 = 28

⇒ LHS = RHS

4. • and ×, 4 and 3

Given: 8 × 3 + 4 = 28

After interchanging the signs and numbers we get;

⇒ 8 + 4 × 3 = 28

⇒ 8 + 12 = 28

⇒ 20 ≠ 28

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 3".

Given: 100, 81, 64, 49, ?, 25

The logic followed here is:

10² = 100

92 = 81

82 = 64

72 = 49

62 = 36

52 = 25

So, 36 will come at the place of question mark.

Hence, the correct answer is "Option 2".

Given:

Total members = 9

Members to be selected = 4

Formula used:

Combination = ^_nC_r

nCr = n! ÷ [r! × (n − r)!]

Calculation:

Number of sub-committees = 9C4

⇒ 9C4 = 9! ÷ (4! × 5!)

⇒ (9 × 8 × 7 × 6 × 5!) ÷ (4 × 3 × 2 × 1 × 5!)

⇒ (9 × 8 × 7 × 6) ÷ (4 × 3 × 2 × 1)

⇒ 3024 ÷ 24

⇒ 126

∴ Number of different sub-committees = 126.

The position and positional values or English Alphabets are:

The logic followed here is:

Similarly,

So, GBNJMZ is coded as HCOKNA.

Hence, the correct answer is "Option 1".

Hence, the correct answer is "Option 3".

BODMAS Rule:

Given equation: 16 ÷ 4 + 8 - 3 × 2 = 31

Let's check each option one by one.

1. ÷ and -

Given: 16 ÷ 4 + 8 − 3 × 2 = 31

After interchanging the signs we get;

⇒ 16 − 4 + 8 ÷ 3 × 2 = 31

⇒ 16 − 4 + 2.67 × 2 = 31

⇒ 16 − 4 + 5.33 = 31

⇒ 21.33 - 4 = 31

⇒ 17.33 ≠ 31

⇒ LHS ≠ RHS

2. + and ×

Given: 16 ÷ 4 + 8 − 3 × 2 = 31

After interchanging the signs we get;

⇒ 16 ÷ 4 × 8 − 3 + 2 = 31

⇒ 4 × 8 − 3 + 2 = 31

⇒ 32 − 3 + 2 = 31

⇒ 34 - 3 = 31

⇒ 31 = 31

⇒ LHS = RHS

3. × and ÷

Given: 16 ÷ 4 + 8 − 3 × 2 = 31

After interchanging the signs we get;

⇒ 16 × 4 + 8 − 3 ÷ 2 = 31

⇒ 16 × 4 + 8 − 1.5 = 31

⇒ 64 + 8 − 1.5 = 31

⇒ 72 − 1.5 = 31

⇒ 70.5 ≠ 31

⇒ LHS ≠ RHS

4. - and ×

Given: 16 ÷ 4 + 8 − 3 × 2 = 31

After interchanging the signs we get;

⇒ 16 ÷ 4 + 8 × 3 − 2 = 31

⇒ 4 + 8 × 3 − 2 = 31

⇒ 4 + 24 − 2 = 31

⇒ 28 − 2 = 31

⇒ 26 ≠ 31

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 2".

BODMAS Rule:

Decoding the given information:

Given equation: 18 - 6 × 3 + 2 ÷ 4 = ?

Now replacing the sign from left to right using BODMAS Rule, we get:

⇒ 18 + 6 ÷ 3 − 2 × 4 = ?

⇒ 18 + 2 − 2 × 4 = ?

⇒ 18 + 2 − 8 = ?

⇒ 20 − 8 = ?

⇒ 12 = ?

Hence, the correct answer is "Option 1".

Family Chart:

Given: A is the sister of B. B is the brother of C. C is the son of D.

Clearly, A is daughter of D.

Hence, the correct answer is "Option 1".

Family Chart:

Given: M is the mother of N. N is the father of P. Q is the son of M.

Clearly, Q is uncle of P.

Hence, the correct answer is "Option 1".

Given: You see someone drop their wallet on the street. 

Logic: The ethical and responsible action is to return the wallet to its owner.

1. Ignore → Ignoring the situation means you are not helping the person recover their lost property. Ethically, this is not the right action. 2.  Keep it → Keeping someone else's wallet is considered dishonest and unethical, and it may also be illegal because it involves taking someone else's property. Ethically, this is not the right action.
2. Donate it → Donating the money or wallet without the owner’s permission is still misusing someone else's property, so it is not appropriate. Ethically, this is not the right action.
3. Return it → The correct and ethical action is to return the wallet to its rightful owner or give it to the nearest police station or authority so the owner can get it back. Ethically, this is the right action.

Thus, 'Return it' is the right Course of Action.

Hence, the correct answer is "Option 4".

The logic followed here is:

Logic: a $ b = (a + b)²

1. 3 $ 4 = 81 → (3 + 4)² = 7² = 49 ≠ 81
2. 2 $ 4 = 36 → (2 + 4)2 = 62 = 36
3. 5 $ 6 = 121 → (5 + 6)2 = 112 = 121
4. 1 $ 2 = 9 → (1 + 2)2 = 32 = 9

Thus, '3 $ 4 = 81' is the odd one out.

Hence, the correct answer is "Option 1".

Statement: All smartphones are gadgets. Some gadgets are expensive. All expensive things are insured.

The least possible Venn diagram for the given statement is:

 

Conclusions:

I. Some gadgets are insured. - True (Because Some gadgets are expensive. All expensive things are insured, which means Some gadgets are insured)

II. Some smartphones are expensive. - False (There is no definite relation between smartphones and expensive, it can be possible only)

Thus, only I follows.

Hence, the correct answer is "Option 1".

Given word: PREACHER

1. RECAP → PREACHER → Word can be formed.
2. PARCH → PREACHER → Word can be formed.
3. PEACH → PREACHER → Word can be formed.
4. CARES → PREACHER → Word cannot be formed as 'S' is missing.

So, CARES is the word which cannot be formed using the letters of the word PREACHER.

Hence, the correct answer is "Option 4".

The logic followed here is:

Similarly,

Thus, RCEETSA is to RAEESCT.

Hence, the correct answer is "Option 4".
