Question 352

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

Directions

In the following question, a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.

D9Y, J27S, P81M, V243G, ?

  1. AOption (a)

    A324B

  2. BOption (b)

    C729B

  3. COption (c)

    B729A

  4. DOption (d)

    A729B

View answer & explanation

Correct answer

Answer: (c)C.

B729A

Why this answer is correct

Logic Followed here is,

⇒ D + 6 = J; J + 6 = P; P + 6 = V; V + 6 = B

⇒ 9; 9 × 3 = 27; 27 × 3 = 81; 81 × 4 = 243; 243 × 3 = 729

⇒ Y – 6 = S; S – 6 = M; M – 6 = G; G – 6 = A

Hence, B729A will be the next term.

Question 353

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

Hemant walks from his house and moves 4 meters towards North. He turns at 90° to his right and moves 3 meters. He takes another 90° turn to the right and walks 4 meters. From here Hemant turns 90° to the left and moves for another 1 meter. He finally turns 90° to the right and moves for another 3 meters, his final destination. What is the shortest distance between the starting and destination points?

  1. AOption (a)

    4 meters

  2. BOption (b)

    5 meters

  3. COption (c)

    7 meters

  4. DOption (d)

    8 meters

View answer & explanation

Correct answer

Answer: (b)B.

5 meters

Why this answer is correct

Path followed is :

Using Pythagoras theorem, we get :

HQ2 = HP2 + PQ2

HQ2 = 42 + 32

HQ = 5 meters

Therefore, Option 2 is the correct answer.

Answer: (c)C.

more than three

Why this answer is correct

  1. S was seated second to the left of T and to the immediate right of U. 

  2. Y was seated second to the right of W. One person was seated between Y and Z when counted from the right of Y. V and Y were immediate neighbours. 

Four persons were seated between W and X when counted from the left of X

Hence, option 3 is the correct answer

Why this answer is correct

The positions of the letters according to the English alphabet series:

The pattern for this code is as follows;

1) 

2) 

3) 

4) 

Hence, "HTYU" is the correct answer.

Question 357

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

Which letter will be on the face opposite to the face with the letter ‘b’?

  1. AOption (a)

    e

  2. BOption (b)

    m

  3. COption (c)

    o

  4. DOption (d)

    i

View answer & explanation

Correct answer

Answer: (a)A.

e

Why this answer is correct

Adjacent elements of letter b =m, o, i, l

Adjacent elements can never be on the opposite surface of a particular element.

The only element left is ‘e’.

Hence, ’e’ will be opposite to the face having ‘b’.

Question 358

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.

BE10, FI54, JM130, ?

  1. AOption (a)

    NM234

  2. BOption (b)

    NM345

  3. COption (c)

    NQ234

  4. DOption (d)

    NQ238

View answer & explanation

Correct answer

Answer: (d)D.

NQ238

Why this answer is correct

Refer the English alphabetical series for the numerical values of letters.

The pattern followed here is:

BE10 → B = 2, B + 3 = E, E = 5, 2 × 5 = 10

FI54 → F = 6, F + 3 = I, I = 9, 6 × 9 = 54

JM130 → J = 10, J + 3 = M, M = 13, 10 × 13 = 130

First letter of missing term will be J + 4 = N

N = 14, N + 3 = Q, Q = 17, 14 × 17 = 238

Hence, answer is NQ238.

Question 359

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

In the following question, select the odd word from the given alternatives.

  1. AOption (a)

    Blacksmith : Anvil

  2. BOption (b)

    Carpenter : Saw

  3. COption (c)

    Barber : Scissor

  4. DOption (d)

    Goldsmith : Ornaments

View answer & explanation

Correct answer

Answer: (d)D.

Goldsmith : Ornaments

Why this answer is correct

Logic: We have to eliminate the odd pair of the following:

Option 1: Blacksmith : Anvil

Anvil is the equipment used by the blacksmith for forging purposes.

Option 2: Carpenter : Saw

A saw is a tool used by carpenters for making furniture.

Option 3: Barber : Scissor

Barber uses scissors for cutting or making hair.

Option 4: Goldsmith : Ornaments

Goldsmith makes ornament. And ornament is not any kind of tool.

As it can be seen that all options are analogous except "Option 4".

Hence, the correct answer should be "Option 4 : Goldsmith : Ornaments".

Question 360

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

In a certain code language, 'CLOUD' is written as 'DMUAE' and 'WHITE' is written as ‘XIOUI’.

How will 'WATER' be written in that language?

  1. AOption (a)

    XEUIS

  2. BOption (b)

    XEUIT

  3. COption (c)

    XBUFS

  4. DOption (d)

    XEVIS

View answer & explanation

Correct answer

Answer: (a)A.

XEUIS

Why this answer is correct

The logic followed here is:

Consonants: +1

Vowels: Next Vowel

'CLOUD' is written as 'DMUAE'.

'WHITE' is written as ‘XIOUI’

Similarly, for 'WATER'

'WATER' is coded as 'XEUIS'.

Hence, the correct answer is "Option 1".
