Question 741

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Find the next term of the following series.

-2,        5,         24,       61,       122,     213,     ?

  1. AOption (a)

    240

  2. BOption (b)

    340

  3. COption (c)

    341

  4. DOption (d)

    313

View answer & explanation

Correct answer

Answer: (b)B.

340

Why this answer is correct

If we see the pattern carefully then we can observe that

13 – 3 = -2

23 – 3 = 5

33 – 3 = 24

43 – 3 = 61

53 – 3 = 122

63 – 3 = 213

Therefore, the next term is, 73 – 3 = 340

Hence, correct answer is in option 4.

Question 743

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

From the given options, which answer figure / figures can be formed by folding the figure given in the question?

  1. AOption (a)

    2

  2. BOption (b)

    4

  3. COption (c)

    3

  4. DOption (d)

    1

View answer & explanation

Correct answer

Answer: (c)C.

3

Why this answer is correct

When we fold a given figure then we get,

By solving the options:

 → It cannot be formed because opposite phase are adjacent to each other.

 → It cannot be formed because opposite phase are adjacent to each other.

 → It can be formed because there is no opposite phase adjacent to each other.

 →  It cannot be formed because opposite phase are adjacent to each other.

Hence, (3) is the correct answer.

Question 744

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Eight children, A, G, K, M, N, R, S and T are sitting around a circular table facing the centre and at equal distance from each other (not necessarily in the same order). R is sitting to the immediate right of G and third to the left of T. S is sitting to the immediate left of T and fourth to the right of A. N is sitting to the immediate right of R and third to the left of K. Which of the following pair is sitting opposite to each other?

  1. AOption (a)

    MN

  2. BOption (b)

    RS

  3. COption (c)

    AG

  4. DOption (d)

    KT

View answer & explanation

Correct answer

Answer: (a)A.

MN

Why this answer is correct

Eight children: A, G, K, M, N, R, S and T

  1. R is sitting to the immediate right of G and third to the left of T

  2. S is sitting to the immediate left of T and fourth to the right of A

  3. N is sitting to the immediate right of R and third to the left of K

This implies that M will occupy the remaining position

Thus, the final arrangement is:

Hence, M and N are sitting opposite to each other

Question 745

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Remya's birthday is on Wednesday 10th March. On what day of the week will be Deepthi's birthday in the same year if Deepthi was born on 15th June?

  1. AOption (a)

    Tuesday

  2. BOption (b)

    Wednesday

  3. COption (c)

    Monday

  4. DOption (d)

    Thursday

View answer & explanation

Correct answer

Answer: (a)A.

Tuesday

Why this answer is correct

Remya's birthday → Wednesday 10th March

Deepthi's birthday → 15th June

So, March has remaining → 21 Days

April → 30 Days

May → 31 Days

June → 15 Days

Total days → 97 Days

Dividing 97 days by 7 (as there are 7 days in a week).

We get the remainder 6.

Thus, 6 days ahead of Remya's birthday will be Tuesday which is Deppthi's birthday.

Hence, 'Tuesday' is the correct answer.

Question 746

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Four pairs of number have been given, out of which three are alike in some manner, while one is different. Choose out the odd one.

  1. AOption (a)

    39 - 12

  2. BOption (b)

    60 - 25

  3. COption (c)

    12 - 22

  4. DOption (d)

    59 - 8

View answer & explanation

Correct answer

Answer: (d)D.

59 - 8

Why this answer is correct

The pattern followed here is:

The addition is two numbers is a multiple of 17.

Option 1 → 39 - 12 → 39 + 12 = 51 → 17 × 3 = 51

Option 2 → 60 - 25 → 60 + 25 = 85 → 17 × 5 = 85

Option 3 → 12 - 22 → 12 + 22 = 34 → 17 × 2 = 34

Option 4 → 59 - 8 → 59 + 8 = 67, Not divisible by 17.

All except, '59 - 8' follow the same pattern.

Hence, '59 - 8' is different from others.

Question 747

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Read the following codes carefully, then respond to the questions.

Using a specific code,

The lyrics of "Live Today Like Last" are written as "ra mu pe ka."

The song's lyrics "Live Like A King" are written as "su ka pe ke."

The lyrics to "Be Like Last King" are written as "pe na ke ra."

The spelling of "A Good Day Today" is "da ku mu su."

Which of the following may be the code for 'Day Was Good' in the given code language?

  1. AOption (a)

    da me mu

  2. BOption (b)

    su pe ma

  3. COption (c)

    ku pa da

  4. DOption (d)

    su mu ku

View answer & explanation

Correct answer

Answer: (c)C.

ku pa da

Why this answer is correct

We can understand the logic by following figure:

By 1st, 2nd and last equations we come to know that:

Today is coded as "mu" &  A is coded as "Su".

Now in the last equation we can conclude that 'good day' is commonly coded as "da ku".

Now checking all the options one by one for 'Day Was Good':

1) da me mu → Incorrect (ku is not present)

2) su pe ma → Incorrect (da ku both are not present)

3) ku pa da → Correct  (Both ku & da are present)

4) su mu ku → Incorrect (da is not present)

Hence the correct answer is "ku pa da".

Hence, QR is the correct answer.

Question 749

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 1

Read the given statement and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions is true based on the given statement.

Statement: S > M ≥ P < K = U < T

Conclusions:

I. P < T

II. K > S

  1. AOption (a)

    Only I is true

  2. BOption (b)

    Only II is true

  3. COption (c)

    Neither I nor II is true

  4. DOption (d)

    Both I and II are true

View answer & explanation

Correct answer

Answer: (a)A.

Only I is true

Why this answer is correct

The given statement is: S > M ≥ P < K = U < T

Conclusions:

I. P < T → True (as P < K = U < T given; so P < T is true).

II. K > S → False (as S > M ≥ P < K gives either S > K or S < K and no definite relation between K and S can be determined).

Hence, the correct answer is “Only I is true”.

XWTU

Why this answer is correct

The positional value of alphabet series is;

Now the pattern follow in first pair is;

Hence, the correct answer is "XWTU".
