Reasoning PYQs

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

Conclusions:

Option 1) Socrates is not mortal → Does not follow (As all men are mortal and Socrates is a man. As whole Socrates comes in man which whole comes in mortal, therefore it is false.)

Option 2) Socrates is immortal → Does not follow (As all men are mortal and Socrates is a man. As whole Socrates comes in man which whole comes in mortal, therefore it is false.)

Option 3) Socrates is a god → Does not follow (As all men are mortal and Socrates is a man. As whole Socrates comes in man which whole comes in mortal, therefore it is false.)

Option 4) Socrates is mortal → Follow (As all men are mortal and Socrates is a man. As whole Socrates comes in man which whole comes in mortal, therefore it is true.)

∴ Here, Only conclusion 4 follows.​

Hence, the correct answer is "Option 4".

The logic followed here is:

Option 1) All birds can swim → This conclusion does not follow because the given statements mention that some birds cannot swim, which contradicts this conclusion.

Option 2) Some birds are fish → This conclusion does not follow as the statements provide no relationship between birds and fish.

Option 3) Some birds cannot fly → This conclusion is incorrect because the statement All birds can fly implies that no bird is unable to fly.

Option 4) Some birds can fly → Since All birds can fly, it logically follows that some birds can fly (assuming the existence of birds).

The universal statement All birds can fly guarantees that every bird possesses the ability to fly. Therefore, it is logically certain that some birds can fly. The other options either contradict the given statements or introduce information that cannot be inferred from them.

Hence, the correct answer is "Option 4".

The logic followed here is:

Hence, "Option 3" is the correct answer

The logic followed here is:

​​

Hence, "Option 2" is the correct answer.

The logic followed here is:

D is to H

Similarly,

J is to

​

​

Hence, "Option 4" is the correct answer.

The logic followed here is:

"TRIP" is written as "USJQ"

Similarly,

"JUMP" is written

​

​​

Hence, "Option 4" is the correct answer.

The logic that is followed in the given steps is given as follows:

1. Word are arranged in ascending order according to the English dictionary order i.e. alphabetical order right end.

2. Number are arranged in descending order from the left end.

3. In each step only alternately one number and one word is shifted, starting with the number.

This process is repeated till we obtained the final output.

Input: cat 90 24 tree 48 75 flower bush

Step 1: 90 cat 24 tree 48 75 flower bush

Step II: 90 bush cat 24 tree 48 75 flower

Step III: 90 bush 75 cat 24 tree 48 flower

Step IV: 90 bush 75 cat flower 24 tree 48

Step V: 90 bush 75 cat flower 48 24 tree

Thus, Numbers descending left; words in alphabetical order right

Hence, "Option 4" is the correct answer.

Decoding signs:

Given: 18/6 - 2 + 8 = ?

18/6 - 2 + 8 = ? ⇒ 18 + 6 × 2 - 8 = ?

⇒ 18 + 6 × 2 - 8 = ?

⇒ 18 + 12 - 8 = ?

⇒ 30 - 8 = ?

⇒ 22 = ?

Hence, "Option 4" is the correct answer.

The logic followed here is:

​​Option 1) 64 → Even number

Option 2) 49 → Odd number

Option 3) 32 → Even number

Option 4) 48 → Even number

Hence, "Option 2" is the correct answer.

The logic followed here is:

Knife: Cut → A knife is used to cut.

Similarly,

Pen: ? → A pen is used to write.

Hence, "Option 3" is the correct answer.

The logic followed here is:

Thus, the missing term in the series is 720.

Hence, the correct answer is "Option 3".

Then logic followed here is:

123, 213, and 312 are composed of the digits 1, 2, and 3 only, just in different orders.

Whereas,

212 repeats the digit '2' and does not include the digit '3'.

So, 212 is the odd one from the given options.

Hence, the correct answer is "Option 3".

The pattern is a shift of +3 in the alphabetical order.

Now, we apply the same logic to D to find the corresponding letter.

The letter that corresponds to the 7^th position is G, matches 

Hence, the correct answer is "Option 3".

The logic followed here is:

Statement 1: All metals are good conductors of electricity.

Statement 2: Copper is a metal.

Since copper is a metal and all metals are good conductors, we can conclude that copper is a good conductor of electricity.

Thus,  Copper is a good conductor.

Hence, the correct answer is "Option 4"

The logic followed here is:

                                                                                             

The number 108 does not follow this pattern; it should be 105 to continue the series correctly.

Thus, the wrong number in the series is 108.

Hence, the correct answer is "Option 4".

BODMAS Rule:

According to the question, the signs are interchanged as follows:

Now, given the equation: 30 − 5 + 10 ÷ 5 = ?

After interchanging the specified signs, the new equation is:

30 × 5 − 10 + 5 = ?

Perform operations according to BODMAS:

⇒ 30 × 5 − 10 + 5

⇒ 150 − 10 + 5

⇒ 140 + 5

⇒ 145

Hence, the correct answer is "Option 2".

The pattern is: +3, +2, +2, +0, -2.

For 'FROST' related to 'ITQSR':

Applying the same logic to 'CHALK':

Hence, the correct answer is "Option 3".

The block "AA" shifts one position to the right in each successive term:

Term 1: "AA" occupies positions 1–2 → AAGHGHGH

Term 2: "AA" occupies positions 2–3 → GAAHGHGH

Term 3: "AA" occupies positions 3–4 → GHAAGHGH

Term 4: "AA" occupies positions 4–5 → GHGAAHGH

Term 5: "AA" occupies positions 5–6 →  GHGHAAGH

Term 6: "AA" occupies positions 6–7 → GHGHGAAH

Term 7: "AA" occupies positions 7-8 → GHGHGHAA

Hence, the correct answer is "Option 1".

The logic followed here is:

 

Profligate is the opposite of Frugality,

Whereas,

Mendacious is the opposite of Truth, matching the same antonym relationship.

Hence, the correct answer is Mendacious : Truth.

Statements:

1. No pens are pencils.

2. Some pencils are erasers.

The least possible venn diagram is given:

Conclusions:

I. Some erasers are not pens -True(because Some erasers are pencils and no pencils are pen, it implies that the part of eraser is pencil can never be pen).

II. No pens are erasers - False(because there is no definite relation is given so it can be possible only).

Thus, Only I follows.

Hence, the correct answer is "Option 3".
