Reasoning PYQs

Thus, option 1 is exactly the same as the one given.

Hence, the correct answer is "Option 1".

Given equation: {{(15 + 3) - (4 × 2)} ÷ (4 - 6)} × 5 = 10

BODMAS Rule:

Let's check each option one by one.

1. + and -

Given equation: {{(15 + 3) - (4 × 2)} ÷ (4 - 6)} × 5 = 10

After interchanging the signs we get;

⇒ {(15 − 3) + (4 × 2)} ÷ (4 + 6) × 5} = 10

⇒ {12 + 8} ÷ 10 × 5} = 10

⇒ {20 ÷ 10 × 5} = 10

⇒ {2 × 5} = 10

⇒ 10 = 10

⇒ LHS = RHS

2. + and x

Given equation: {{(15 + 3) - (4 × 2)} ÷ (4 - 6)} × 5 = 10

After interchanging the signs we get;

⇒ {(15 × 3) − (4 + 2)} ÷ (4 − 6) + 5} = 10

⇒ {45 − 6} ÷ (-2) + 5} = 10

⇒ {45 − 6} ÷ (-2) + 5} = 10

⇒ {39 ÷ (-2) + 5} = 10

⇒ {-19.5 + 5} = 10

⇒ -14.5 ≠ 10 

⇒ LHS ≠ RHS

3. + and ÷

Given equation: {{(15 + 3) - (4 × 2)} ÷ (4 - 6)} × 5 = 10

After interchanging the signs we get;

⇒ {(15 ÷ 3) − (4 × 2)} + (4 − 6) × 5} = 10

⇒ {5 − 8} + (-2) × 5} = 10

⇒ {(-3)} + (-2) × 5} = 10

⇒ {(-3)} + (-10)} = 10

⇒ -13 ≠ 10

⇒ LHS ≠ RHS

4. x and ÷

Given equation: {{(15 + 3) - (4 × 2)} ÷ (4 - 6)} × 5 = 10

After interchanging the signs we get;

⇒ {(15 + 3) − (4 ÷ 2)} × (4 − 6) ÷ 5 = 10

⇒ {18 − 2} × (−2)} ÷ 5 = 10

⇒ {16 × (−2)} ÷ 5 = 10

⇒ -32 ÷ 5 = 10

⇒ -6.4 ≠ 10

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 1".

BODMAS Rule:

Decoding the given information:

Let's check each option one by one.

1. 7 × 42 + 7 ÷ 3 - 4 = 42 - 6 ÷ 2 - 7

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

⇒ 7− 42 ÷ 7 + 3 × 4 = 42 × 6 + 2 × 7

⇒ 7− 6 + 3 × 4 = 252 + 14

⇒ 7 − 6 + 12 = 266

⇒ 19 − 6 = 266

⇒ 13 ≠ 266

⇒ LHS ≠ RHS

2. 50 × 49 + 7 ÷ 1 + 2 = 30 + 6 ÷ 9 - 5

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

⇒ 50 − 49 ÷ 7 + 1 ÷ 2 = 30 ÷ 6 + 9 × 5

⇒ 50 − 7 + 0.5 = 5 + 9 × 5

⇒ 50 − 7 + 0.5 = 5 + 9 × 5

⇒  50.5 - 7 = 5 + 45

⇒  43.5 ≠ 50

⇒ LHS ≠ RHS

3. 6 × 16 + 2 ÷ 4 - 3 = 14 + 7 ÷ 4 - 2

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

⇒ 6 − 16 ÷ 2 + 4 × 3 = 14 ÷ 7 + 4 × 2

⇒ 6 − 16 ÷ 2 + 4 × 3 = 14 ÷ 7 + 4 × 2

⇒ 6 − 8 + 4 × 3 = 2 + 4 × 2

⇒ 6 - 8 + 12 = 2 + 8

⇒ 18 - 8 = 10

⇒ 10 = 10

⇒ LHS = RHS

4. 9 × 16 + 8 ÷ 6 - 3 = 32 + 32 ÷ 4 - 8

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

⇒ 9 − 16 ÷ 8 + 6 × 3 = 32 ÷ 32 + 4 × 8

⇒ 9 − 2 + 6 × 3 = 1 + 4 × 8

⇒ 9 − 2 + 6 × 3 = 1 + 4 × 8

⇒ 9 - 2 + 18 = 1 + 32

⇒ 27 - 2 = 33

⇒ 25 ≠ 33

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 3".

Family Chart:

Given: Pointing to a man, Ravi said, "He is the son of my father's only son."

Clearly, the man is son of Ravi.

Hence, the correct answer is "Option 4".

Family Chart:

Given: Q is the daughter of R, who is the mother of S. T is the father of Q.

Clearly, T is father of S.

Hence, the correct answer is "Option 4".

Statement: In an attempt to modernize agricultural output, the government has introduced AI-based crop surveillance tools in rural zones with high farmer suicide rates.

Now,

Judgements:

1.Traditional methods of crop monitoring are entirely ineffective. - Does not follow (Because the statement only says the government wants to modernize agriculture. It does not say traditional methods are completely ineffective. Modernization does not imply total failure of existing methods.)

2.Technological interventions may indirectly improve farmer well-being. - Follows (Because the AI tools are introduced in areas with high farmer suicide rates. This suggests the government expects technology to improve agricultural output. Better output could reduce financial stress and potentially improve well-being. The connection between technology and farmer well-being is implied.)

Thus, only judgement 2 follows.

Hence, the correct answer is "Option 2".

The logic followed here is:

1. 3 + 4 = 7
2. 5 + 6 = 11
3. 2 + 2 = 5

2 + 2 = 4 ≠ 5

4. 8 + 1 = 9

All options except "2 + 2 = 5" is mathematically correct.

Hence, the correct answer is "Option 3".

Statement: All poets are writers.Some writers are critics. No critic is a fool.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some poets are critics. - False (Some poets being critics is possible but it is not definite. So, the conclusion is false)

II. Some writers are not fools. - True (Some writers are critics. No critic is a fool, which means some writers who are critics are not fools)

Thus, only II follows.

Hence, the correct answer is "Option 2".

The logic followed here is:

• Asia → Continent
• Europe → Continent
• Africa → Continent
• Australia → Continent
• Brazil → Country

All options except "Brazil" are continents, while Brazil is a country (located in South America).

Hence, the correct answer is "Option 3".

Given word: RELATIONSHIP

1. POSHER → RELATIONSHIP 2. EARTH → RELATIONSHIP 3. POLISH → RELATIONSHIP 4. THRILLS → RELATIONSHIP → extra letter 'L' is not found in the main word.

So, THRILLS is the word which uses an extra letter not found in the main word.

Hence, the correct answer is "Option 4".

Given letters: MOTLETEE

1. OMLETTEE → Incorrect spelling

2. METELOTE → Not meaningful

3. EMOTETLE → Not meaningful

4. OMELETTE → Uses all letters correctly and makes a meaningful word.

So, OMELETTE is the meaningful which word can be formed from the letters "MOTLETEE".

Hence, the correct answer is "Option 4".

The position and positional values or English Alphabets are:

The logic followed here is:

Similarly,

Thus, VISION is written as XKVKQQ.

Hence, the correct answer is "Option 3".

The position and positional values or English Alphabets are:

Given: CBA, DCB, EDC, FED, ?

 

The logic followed here is:

So, GFE comes next.

Hence, the correct answer is "Option 2".

The logic followed here is:

1. Geographical Phenomena - Geographical phenomena are natural events or processes that occur on the Earth’s surface and affect its physical features and environment.

2. Earthquake - A sudden shaking of the Earth’s surface.

3. Cyclone - A large-scale air mass that rotates around a strong center of low atmospheric pressure.

4. Volcano - An opening in the Earth's crust that allows lava, ash, and gases to escape.

Earthquake, Cyclone, and Volcano are specific examples of geographical phenomena.

Geographical Phenomena is a category, not a specific event.

Thus, Geographical Phenomena is the odd one out.

Hence, the correct answer is "Option 1".

The position and positional values or English Alphabets are:

Given series: AZ, BY, CX, DW, ?

The logic followed here is:

so, EV comes next.

Hence, the correct answer is "Option 1".

Given:

Distance₁ = 5 km

Time₁ = 1 hour

Distance₂ = 5 km

Time₂ = 30 minutes = 0.5 hour

Formula used:

Average speed = Total distance ÷ Total time

Calculation:

Total distance = 5 + 5 = 10 km

Total time = 1 + 0.5 = 1.5 hours

⇒ Average speed = 10 ÷ 1.5

⇒ Average speed = 20 ÷ 3

⇒ Average speed = 6.67 km/h

∴ Average speed of the whole journey = 6.67 km/h.

The logic followed here is:

Logic: a @ b = (a × b) + (a + b)

5 @ 2 = 17 → (5 × 2) + (5 + 2) = 10 + 7 = 17

6 @ 3 = 27 → (6 × 3) + (6 + 3) = 18 + 9 = 27

Similarly,

7 @ 4? → (7 × 4) + (7 + 4) = 28 + 11 = 39

So, 39 will come in the place of ?.

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: a @ b = a2 + b

9 @ 1 = 82 → 92 + 1 = 81 + 1 = 82

6 @ 2 = 38 → 6² + 2 = 36 + 2 = 28

Similarly,

7 @ 3 → 72 + 3 = 49 + 3 = 52

Hence, the correct answer is "Option 3".

Given: You're an administrative officer. You see bias in staff recruitment. What should you do?

1. Stay silent to avoid conflict → Avoids conflict but allows injustice to continue. 2. Raise objection with evidence → Professional, ethical, and constructive approach. It addresses the issue properly.  3. Inform selected candidate quietly → Unprofessional and may create unnecessary complications.  4. Delay the joining process → Avoids the real issue instead of solving it.

Thus, "Raise objection with evidence" is the correct Course of Action.

Hence, the correct answer is "Option 2".

Given equation: 120 ÷ 6 x 5 + 10 - 4 = ?

BODMAS Rule:

Decoding the given information:

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

⇒ 120 × 6 ÷ 5 − 10 + 4 = ?

⇒ 120 × 1.2 − 10 + 4 = ?

⇒ 144 − 10 + 4 = ?

⇒ 148 − 10 = ?

⇒ 138 = ?

Hence, the correct option is "Option 2".
