Reasoning PYQs

The logic followed here:

7 × 2 = 14

14 − 2 = 12

12 × 2 = 24

24 − 2 = 22

The pattern is:

×2, −2, ×2, −2, ...

22 × 2 = 44

Hence, the next number is 44.

Hence, the correct answer is Option 1.

Wait for higher authorities to act – Not appropriate (Immediate environmental damage is occurring, and delaying action can worsen the situation.)

Fine the factory after a month – Not appropriate (Delaying enforcement allows the factory to continue polluting and does not address the urgency of the issue.)

Secretly record the act and leak it – Not appropriate (Leaking information is not an official or lawful action and may create legal and ethical complications.)

Take legal action and inform environment department – Appropriate (It ensures immediate lawful intervention, proper documentation, and coordination with the concerned environmental authorities.)

Hence, the correct answer is option 4.

Shortcut Trick

Total cost of 3 pens = 3 × ₹12 = ₹36.

Remaining amount for 2 notebooks = ₹76 − ₹36 = ₹40.

Cost of 1 notebook = ₹40 ÷ 2 = ₹20.

∴ The correct answer is ₹20.

Alternate Method

Given:

Number of pens = 3

Cost of one pen = ₹12

Number of notebooks = 2

Total bill amount = ₹76

Formula Used:

Total Cost = (Number of pens × Price per pen) + (Number of notebooks × Price per notebook)

Calculations:

⇒ Cost of 3 pens = 3 × 12 = ₹36

⇒ Let the cost of one notebook be ₹x

⇒ 36 + 2x = 76

⇒ 2x = 76 − 36

⇒ 2x = 40

⇒ x = 40 ÷ 2

⇒ x = ₹20

∴ The correct answer is ₹20.

Additional Information

Linear Equations

Problems involving fixed prices and quantities are solved using linear equations in the form ax + by = Total, where x and y are the unit prices.

Unitary Method

This method involves finding the value of a single unit (unit rate) to find the value of any number of units.

Verification Rule

Always check the result by substituting the values back: (3 × 12) + (2 × 20) = 36 + 40 = 76, which confirms the answer is correct.

The logic followed here:

F → H (+2)

R → U (+3)

I → M (+4)

E → J (+5)

N → T (+6)

D → K (+7)

The pattern is increasing by +2, +3, +4, +5, +6, +7.

CANDLE:

C → E (+2)

A → D (+3)

N → R (+4)

D → I (+5)

L → R (+6)

E → L (+7)

CANDLE → EDRIRL

Hence, the correct answer is Option 2.

The logic followed here:

Counting from left:

1 → W

2 → %

3 → ^

4 → K

5 → V

6 → P

7 → 1

The 7^th element from the left is 1.

Find the second element from the right of 1.

Elements to the right of 1 are:

I (1^st), 7 (2^nd), E (3^rd), ...

The second element from the right of 1 is 7.

Hence, the correct answer is Option 3.

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

Conclusions:

I. All envelopes can never be parcels → Follow (As no card is a parcel and all cards are envelopes. As whole card comes in envelopes and cannot be parcel, therefore it is true.)

II. No card is a bag → Does not follow (As no card is a parcel, all cards are envelopes and some envelopes are bags. As no direct relation is given between card and bags, therefore it is possible but not definite.)

III. At least some bags are postcards → Does not follow (As no relation with postcards is given, therefore it is false).

∴ Here, Only conclusion I follows.

Hence, "Option 1" is the correct answer.

According to the given information,

Thus, according to the given codes the code 'aa' is for the word 'how'.

Hence, the correct answer is "Option 2".

The logic followed here is:

Hence, "Option 3" is the correct answer.

The mirror image of the given figure is as follow:

 

Hence, the correct answer is "Option 1".

The logic followed here is:

MEK: NVP

And,

GYT: TBG

Similarly,

JWH:?

Hence, "Option 1" is the correct answer.

Given series: L_P_QS_K_P_S_KP_Q_L_ _PQS

Option 1) KPLPQLPSKP→ LKPPQSLKPPQSLKPPQSLK PPQS → (It follows the pattern of: LKPPQS - LKPPQS - LKPPQS - LKPPQS)

Option 2) KPLPLQLSPK → LKPPQSLKPPLSQKPLQSLP KPQS → (It doesn't follow any pattern)

Option 3) KPLPQQLPSK → LKPPQSLKPPQSQKPLQPLS KPQS → (It doesn't follow any pattern)

Option 4) PKLPQPLSKP → LPPKQSLKPPQSPKPLQSLK PPQS → (It doesn't follow any pattern)

Hence, "Option 1" is the correct answer.

Given: 5 – 4 ÷ 9 + 80 x 10 = ?

According to the question, after ‘+’ and ‘–‘ are interchanged and ‘x’ and ‘÷’ are interchanged:

5 – 4 ÷ 9 + 80 x 10 = ? ⇒ 5 + 4 x 9 – 80 ÷ 10 = ?

⇒ 5 + 4 x 9 – 80 ÷ 10 = ?

⇒ 5 + 4 x 9 – 8 = ?

⇒ 5 + 36 – 8 = ?

⇒ 41 – 8 = ?

⇒ 33 = ?

Hence, "Option 1" is the correct answer.

The logic followed here is:

Given word: NIGHTMARES

Thus, Four letters will remain unchanged if each of the letters in the word 'NIGHTMARES' is re-arranged in the English alphabetical order from left to right.

Hence, the correct answer is "Four".

The logic followed here is:

1. All the elements shift anticlockwise including the center element.

Hence, "Option 1" is the correct answer.

The logic followed here is:

Hence, "Option 1" is the correct answer.

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

Conclusions:

I. All tears can never be rivers → Does not follow (As some tears are drops, some drops are streams and all streams are rivers. As no direct relation is given between tears and rivers, therefore it is false.)

II. Some drops are rivers → Follow (As some drops are streams and all streams are rivers. As whole streams comes in rivers and has some part common with drops, therefore it is true.)

III. All tears being streams is a possibility → Follow (As some tears are drops, some drops are streams. As no statements restricts tears from being streams, therefore it is possible.)

∴ Here, Both II and III conclusion follow.

Hence, "Option 4" is the correct answer.

The mirror image of the given figure is as follow:

Hence,  the correct answer is "option 3".

The logic followed here is:

Hence, "Option 2" is the correct answer.

The logic followed here is:

'NAME' is written as 'FNBO'

And,

'NANO' is written as 'POBO'

Similarly,

'NAIL' will be written as

Hence, "Option 2" is the correct answer.

The logic followed here is :-

From the given two different cubes the adjacent sides are as shown below :

As V is common on both the dices, it is clear that Q, Z, T, and L are adjacent to it, and the remaining i.e. A will be opposite to it.

Opposite pairs:

Z → L

Q → T

V → A

So, the opposite side of "Q" will be side "T".

Hence, the correct answer is "Option 1".
