Question 1282

RRB Group D 2025• General Intelligence and Reasoning• General Intelligence and Reasoning

Read the given statement(s) and conclusions carefully. Assuming that the information given in the statement(s) is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).

Statements:

All detergents are towels.

All detergents are conditioners.

Conclusions:

(I) Some towels are conditioners.

(II) All conditioners are detergents.

  1. AOption (a)

    Only conclusion (II) follows.

  2. BOption (b)

    Only conclusion (I) follows.

  3. COption (c)

    Neither conclusion (I) nor (II) follows. 

  4. DOption (d)

    Both conclusions (I) and (II) follow.

View answer & explanation

Correct answer

Answer: (b)B.

Only conclusion (I) follows.

Why this answer is correct

Given

Statements:

All detergents are towels.

All detergents are conditioners.

The least possible Venn diagram for the given statement is:

Conclusions:

(I) Some towels are conditioners:

Since all Detergents are Towels, and all Detergents are Conditioners, the Detergents form the part of the Towels that are also Conditioners.

Thus, there is an overlap.

(I) logically follows.

(II) All conditioners are detergents:

This is the converse of Statement 2.

The statements do not provide enough information to guarantee this is true.

There may be conditioners that are not detergents.

(II) does not follow.

So, Only conclusion (I) follows.

Hence, the correct answer is "Option 2".

Answer: (c)C.

32 

Why this answer is correct

BODMAS Table: 

Given equation: 11 − 3 × 88 + 8 ÷ 10 = ? 

Now, ‘+’ ↔ ‘÷’ (interchanged) and ‘−’ ↔ ‘×’ (interchanged), then:

⇒ 11 × 3 − 88 ÷ 8 + 10 = ?

⇒ 33 − 11 + 10 = ?

⇒ 22 + 10 

= 32

Hence, the correct answer is "Option 3".

View answer & explanation

Correct answer

Answer: (b)B.

VYP

Why this answer is correct

Logic followed here is:

Each letter-cluster follows a pattern based on the addition and subtraction of positional values in alphabetical order.

The pattern is: 1st letter + 3 = 2nd letter; 2nd letter - 7 = 3rd letter.

For (1) LOH →

 

For (2) VYP →

For (3) CFY →

 

For (4) ZCV →

  

Therefore, the letter-cluster 'VYP' is the odd one out.

Hence, the correct answer is "Option 2".

For

ABHL is related to FFMP →

URBB is related to ZVGF →

 

The pattern observed is: (Letter Positional Value) + 5, + 4, + 5, + 4.

Similarly, let's find the related term for JDQN:

Therefore, 'JDQN' is related to 'OHVR'.

Hence, the correct answer is "Option 2".

View answer & explanation

Correct answer

Answer: (a)A.

SYDG

Why this answer is correct

Logic followed here is:

The difference between the positional values of consecutive letters in each cluster follows a specific pattern (e.g., +6, +4, +4), except for the odd cluster.

  1. SYDG:

  2. UAEI:

  3. HNRV:

  

  1. XDHL:

 

 

Therefore, the letter-cluster 'SYDG' is the odd one out as it does not follow the +6, +4, +4 pattern.

Hence, the correct answer is "Option 1".
