Why this answer is correct

Given Series:

(Left) 3 1 2 6 9 8 1 3 4 1 6 9 5 1 1 5 9 9 4 2 7 7 8 3 9 8 8 (Right)

Required Pattern:

Odd → Odd → Even

Checking the series:

​(Left) 3 1 2 6 9 8 1 3 4 1 6 9 5 1 1 5 9 9 4 2 7 7 8 3 9 8 8 (Right)

Odd numbers satisfying the condition:

→ 1 in (3 1 2)

→ 3 in (1 3 4)

→ 9 in (9 9 4)

→ 7 in (7 7 8)

→ 9 in (3 9 8)

Therefore, there are 5 such odd numbers.

Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (c)C.

MLP 36

Why this answer is correct

The logic followed here is:

For the Letter Clusters:

Each corresponding letter in the next cluster is obtained by adding 7 to the positional value of the previous letter.

For the Numbers:

The numbers follow a pattern of decreasing by 9 in each step.

The next cluster in the series is MLP 36.

Hence, the correct answer is "Option 3"..

Question 1143

RRB Group D 2025• General Intelligence & Reasoning

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(

Note:

Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting / multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

(25, 12, 148)

  1. AOption (a)

    (40, 13, 210)

  2. BOption (b)

  3. COption (c)

    (38, 15, 212)

  4. DOption (d)

    (19, 35, 214)

View answer & explanation

Correct answer

Answer: (c)C.

(38, 15, 212)

Why this answer is correct

Logic followed here is:

The third number is obtained by multiplying the sum of the first and second numbers by 4.

Logic: (First number + Second number) × 4 = Third number

For (25, 12, 148) →

1st Num2nd Num
2512

Sum of numbers = 25 + 12 = 37

Result = 37 × 4 = 148

 

For (32, 11, 172) →

1st Num2nd Num
3211

Sum of numbers = 32 + 11 = 43

Result = 43 × 4 = 172

 

The pattern observed is: (First Number + Second Number) × 4 = Third Number.

Similarly, let's check the options:

For (38, 15, 212) →

1st Num2nd Num
3815

Sum of numbers = 38 + 15 = 53

Result = 53 × 4 = 212

 

Therefore, the set (38, 15, 212) follows the same logic.

Hence, the correct answer is "Option 3".

Correct answer

Answer: (b)B.

S

Why this answer is correct

Given:

Six friends G, H, I, Q, R and S are sitting around a circular table facing the centre.

  1. Only two people sit between Q and I when counted from the left of I.

  2. H sits second to the left of S.

  3. R sits to the immediate right of S.

  4. R sits to the immediate left of Q.

Arrangement:

Finding third to the right of G:

From G, moving towards the right:

1st right → Q

2nd right → R

3rd right → S

Therefore, S sits third to the right of G.

Hence, the correct answer is "Option 2".

  1. AOption (a)

    XYZ−ACE

  2. BOption (b)

    XZB−ACE

  3. COption (c)

    XYZ−ZBD

  4. DOption (d)

    XZB−ZCD

View answer & explanation

Correct answer

Answer: (b)B.

XZB−ACE

Why this answer is correct

Logic followed here is:

In each pair, the second set of letters is obtained by adding 3 to the positional value of each letter in the first set.

For GIK is related to JLN →

CEG is related to FHJ →

The pattern observed is: (Each letter's positional value) + 3 = Next set's positional value.

Similarly, for the option XZB-ACE:

Therefore, the pair which follows the same pattern is XZB−ACE.

Hence, the correct answer is "Option 2".

BQVH is related to HLZE →

HSJQ is related to NNNN →

The pattern observed is: The letters follow a positional shift of +6, -5, +4, and -3.

Similarly, let's find the related word for JOWF:

Therefore, the code for 'JOWF' is PJAC.

Question 1154

RRB Group D 2025• General Intelligence & Reasoning

In a certain code language,

P + Q means ‘P is the mother of Q’,

P # Q means ‘P is the husband of Q’,

P & Q means ‘P is the sister of Q’ and

P % Q means ‘P is the father of Q’.

How is J related to Z if ‘J # S + R & T % Z’?

  1. AOption (a)

    Father’s mother

  2. BOption (b)

    Mother's mother

  3. COption (c)

    Mother's father

  4. DOption (d)

    Father’s father

View answer & explanation

Correct answer

Answer: (d)D.

Father’s father

Why this answer is correct

Given:

P + Q → P is the mother of Q

P # Q → P is the husband of Q

P & Q → P is the sister of Q

P % Q → P is the father of Q

Expression:

J # S + R & T % Z

Family chain:

T is the father of Z.

R is the sister of T, so R is Z's aunt.

S is the mother of R and T.

J is the husband of S.

Therefore, J is the father of T.

Since T is the father of Z, J becomes Z's grandfather.

Hence, J is Father's father of Z.

Therefore, the correct answer is "Option 4".

Observe the pattern:

GATE → ETGA

From the first word:Last two letters come first in reverse.First two letters move to the end

ETGA → GTAE

3rd and 1st letters comes first.4th and 2nd letters comes then

Check the options:

Option 2: USER - REUS - UESR

(RE) + (US) = REUS 

Now,

REUS → UESR 

So, this follows the same logic.

Hence, the correct answer is "Option 2".
