Reasoning PYQs

Six persons, A, B, C, D, E and F, are sitting in a straight line, all facing the same direction.

1) E is sitting between B and F.

Case(i) :

Case(ii) :

2) A is third to the right of F and E is fourth to the left of A.

Case(i) :

Case(ii) :

Here case (ii) gets eliminated.

3) C is not sitting next to A.

∴ Here, 'C' is sitting between F and D.

Hence, the correct answer is "C".

Given,

Statement:

Ethical behavior fosters trust, but profitability often relies on operational efficiency as well.

Conclusions:

I. Ethical behavior is not sufficient for profitability. - True (Because, the statement says that profitability "often relies on operational efficiency as well." The word "as well" indicates that operational efficiency is another necessary factor, meaning ethical behavior alone is not enough to ensure profitability.)

II. Operational efficiency is required for trust. - False (Because, the statement links ethical behavior to trust, stating that "Ethical behavior fosters trust." It does not establish any connection between operational efficiency and trust.)

So, only conclusion I follows.

Hence, the correct answer is "Option 3".

All conditions are as follows:

 

Priyanka meets all the eligibility criteria for the position, including age, education, and experience.

So, the correct answer is "Priyanka is eligible for the position as she meets all the criteria".

Hence, the correct answer is "Option 2".

Given: Eight people - A, B, C, D, E, F, G, and H, are sitting around a circular table, all facing outward.

D is third to the right of A.

B is sitting opposite D.

G is an immediate neighbor of both D and F.

C sits to the immediate right of F. 

E is third to the right of B.

So, D is sitting to the immediate right of E.

Hence, the correct answer is "Option 1".

Logic followed here is:

The pattern is: (Sum of reverse positional values) - 1.

For READ:

Sum = 9 + 22 + 26 + 23 = 80

Code = 80 - 1 = 79

For DEAR:

Sum = 23 + 22 + 26 + 9 = 80

Code = 80 - 1 = 79

Similarly, let's find the code for DARE:

Sum = 23 + 26 + 9 + 22 = 80

Code = 80 - 1 = 79

Therefore, the code for DARE is 79.

Hence, the correct answer is "Option 4".

Given:

Number of people (n) = 6

Formula used:

The number of ways to arrange 'n' distinct objects in a circle is (n-1)!

Calculation:

Number of ways = (6-1)! = 5!

⇒ 5 × 4 × 3 × 2 × 1

⇒ Number of ways = 120

∴ The correct answer is option (1).

Given:

Distance = 180 km

Formula used:

Time = \(\dfrac{Distance}{Speed}\)

Calculations:

Let original speed be 'S' km/h

Let original time be 'T' hours

New speed = (S + 15) km/h

New time = (T - 1) hours

From the given information, we can set up two equations:

T = \(\dfrac{180}{S}\) ----- (1)

T - 1 = \(\dfrac{180}{S+15}\) ---- (2)

Substitute T from equation (1) into equation (2):

\(\dfrac{180}{S}\) - 1 = \(\dfrac{180}{S+15}\)

⇒ \(\dfrac{180-S}{S}\) = \(\dfrac{180}{S+15}\)

⇒ (180 - S)(S + 15) = 180S

⇒ 180S + 2700 - S² - 15S = 180S

⇒ 2700 - S² - 15S = 0

⇒ S² + 15S - 2700 = 0

Factoring the quadratic equation:

⇒ (S + 60)(S - 45) = 0

Since speed cannot be negative, S = 45.

∴ The original speed of the train is 45 km/h.

The logic followed here is that all the numbers except one are prime numbers.

103 is a prime number (divisible only by 1 and 103).

109 is a prime number (divisible only by 1 and 109).

107 is a prime number (divisible only by 1 and 107).

The number 111 is composite.

→ 111 = 3 × 37

Hence, the correct answer is "Option 2".

The logic followed here is:

Total people = (Rank from the front) + (Rank from the back) - 1

Given:

Ram's rank from the front = 10^th

Ram's rank from the back = 15^th

Applying the formula:

Total people = 10 + 15 - 1

= 25 - 1 = 24

So, there are 24 people in the queue.

Hence, the correct answer is "Option 3".

Sameer's Status Evaluation

Option: 2) Insufficient Data

Reason : The criteria for selection (minimum required percentage, maximum age, required qualifications, minimum experience) are not provided. Without these benchmarks, a definitive decision cannot be made.

Hence, the correct answer is "Option 2".

The logic followed here is that all the numbers except one are perfect squares.

49 = 7²

64 = 8²

81 = 9²

The number 90 is not a perfect square.

Hence, the correct answer is "Option 3".

Given: 

A man walks 4 km north, then turns right and walks 3 km.

Then turns right again and walks 4 km.

Movement of the man is,

So, the shortest distance from his starting point is 3 Km.

Hence, the correct answer is "Option 3".

The pattern followed here is.

Thus, the missing term in the series is 30I-18.

Hence, the correct answer is Option 4.

The logic followed here is,

Hence, the correct answer is Option 1.

Alternate Method Here is the detailed explanation for the pattern:

• First Number: The series starts with 2 and increases by 3 in each consecutive step. Thus, the next number is 11 + 3 = 14.
• Letter: There are two alternate series of letters.
• Series 1: A, B, C... (+1)
• Series 2: Z, Y, X... (-1)

The next letter in the sequence will be the next letter of the first series, which is C.

• Second Number: The series starts with 50 and decreases by 4 in each consecutive step.
• Thus, the next number is 38 - 4 = 34.

By combining the results, the missing term is 14C-34.

The logic followed here is,

For,

1. MNOP : NMOP
2. ABCD : BACD
3. FGHI : GFHI
4. STUV : TSUV

5. WXYZ : XYWZ

**"**WXYZ : XYWZ" does not follow the same logic as others.

Hence, the correct answer is "Option 3".

Decoding symbols for Family Tree:

​Let's decode the relationships step-by-step:

A is the father of B. 

B is the mother of C. 

According to the given information Family Tree Representation:

Thus, A is the Grandfather of C.

Hence, the correct answer is "Option 1"

Given,

Statement:

Online learning has increased student participation.

Conclusions:

I. Students did not participate in physical classes. - False (The statement says online learning "increased" participation, which implies that some participation existed before. It does not state that there was no participation in physical classes.)

II. Technology helps in engaging students. - True (The statement directly links online learning, which is a form of technology, with increased student participation. This indicates that technology is a tool that helps in engaging students.)

So, only conclusion II follows.

Hence, the correct answer is "Option 1".

The relationship between MAVERICK and CONFORMITY is that a MAVERICK is a person who rejects or does not follow CONFORMITY.

Let's analyze the given options:

Iconoclast : Tradition

An iconoclast is a person who attacks cherished beliefs, traditional institutions, or established values.

The relationship here is that an iconoclast is a person who rejects tradition.

This is the closest match to the relationship between the original pair.

Dilettante : Amateur

A dilettante is an amateur. These two words are synonyms, not antonyms or a relationship of opposition.

Ascetic : Monastic

An ascetic is a person who practices severe self-discipline and abstention, often for religious reasons.

Monastic refers to a monk or a style of life associated with monks.

While related, they are not opposites. 

Demagogue : Populace

A demagogue is a political leader who seeks support by appealing to the desires and prejudices of ordinary people rather than by using rational argument.

A populace is the general body of people in a country or region. A demagogue manipulates the populace, but does not reject it.

Altruist : Benefactor

An altruist is a person unselfishly concerned with or devoted to the welfare of others.

A benefactor is a person who gives money or other help to a person or cause.

A benefactor is a type of altruist, so they are not opposites.

Therefore, the pair that most closely matches the relationship between MAVERICK and CONFORMITY is Iconoclast : Tradition.

Hence, the correct answer is "Option 4".

The logic followed here is,

For 'RED' related to 'RFE':

Applying the same logic to 'TOP':

Thus, 'TOP' is coded as "TPQ".

Hence, the correct answer is "Option 2".

Given series: ab_dcabcd_ _bcdc_bcdca_cdc

1. bcadc → abbdc/abcdc/abcdc/dbcdc/accdc → doesn’t follow any pattern

2. ccaab → abcdc/abcdc/abcdc/abcdc/abcdc → follows a certain pattern

3. abbcd → abadc/abcdb/bbcdc/cbcdc/adcdc → doesn’t follow any pattern

4. cadcb → abcdc/abcda/dbcdc/cbcdc/abcdc → doesn’t follow any pattern

Hence, “ccaab” is the correct answer.
