View answer & explanation

Correct answer

Answer: (c)C.

66 years

Why this answer is correct

The equation will be as follows,

Let assume the age of mother and daughter are 8x and 3x respectively.

8x + 12 = 6x + 24

2x = 12

X = 6

Sum of the ages = 8x + 3x

11 (3) = 66

Hence 66 is correct answer.

Question 12

BSPHCL Correspondence Clerk 2025• Test

A certain sum of money was distributed among Darshana, Swati and Nivriti. Nivriti has Rs. 539 with her. If the ratio of the money distributed among Darshana, Swati and Nivriti is 5 : 6 : 7, what is the total sum of money that was distributed?

  1. AOption (a)

    Rs. 1,341

  2. BOption (b)

    Rs. 1,422

  3. COption (c)

    Rs. 1,386

  4. DOption (d)

    Rs. 1,356

View answer & explanation

Correct answer

Answer: (c)C.

Rs. 1,386

Why this answer is correct

Given,

The ratio of the money distributed among Darshana, Swati and Nivriti is 5 : 6 : 7

Darshna : Swati : Nivriti → 5 : 6 : 7

But Nivriti has Rs. 539 with her.

Then,

7 → 539 

1 → 77

The total sum of money = 5 + 6 + 7 = 18

The total sum of money was distributed = 18 x 77 = 1386

Hence, the correct answer is "1386".

Question 13

BSPHCL Correspondence Clerk 2025• Test

Seven children K, L, P, R, T, X and Y are sitting on a straight bench facing towards North. X is sitting immediately left of "Y". 'T' is the immediate neighbour of 'R' and 'P. Neither 'X' nor Y are the immediate neighbours of 'L'. 'P is sitting second to the left of 'L'.

Who is sitting at the second position from the right end?

  1. AOption (a)

    R

  2. BOption (b)

    T

  3. COption (c)

    K

  4. DOption (d)

    P

View answer & explanation

Correct answer

Answer: (c)C.

K

Why this answer is correct

The logic follows here is:

Seven children K, L, P, R, T, X and Y are sitting on a straight bench facing towards North.

  • 'P is sitting second to the left of 'L'.

  • 'T' is the immediate neighbour of 'R' and 'P.

  • X is sitting immediately left of "Y".

  • Neither 'X' nor Y are the immediate neighbours of 'L'.

​

Therefore, the final arrangement will be:

Clearly, 'K' is sitting second from the right end.

Hence, the correct answer is "K".

Question 14

BSPHCL Correspondence Clerk 2025• Test

Two different positions of the same dice are shown having numbers 1 to 6 represented as dots. Find the number on the face opposite the face showing '1'.

  1. AOption (a)

    6

  2. BOption (b)

    4

  3. COption (c)

    3

  4. DOption (d)

    2

View answer & explanation

Correct answer

Answer: (a)A.

6

Why this answer is correct

As '2' and '4' dots are common faces on both the dice, clearly the remaining faces are opposite to each other.

Therefore, '6' will be the number on the face opposite the face showing '1'.

Hence, '6' is the correct answer.

Question 15

BSPHCL Correspondence Clerk 2025• Test

The average age of 30 students is 15 years. If the teacher’s age is also included then the average age increases by 1 year. The age of the teacher is?

  1. AOption (a)

    56

  2. BOption (b)

    46

  3. COption (c)

    35

  4. DOption (d)

    45

View answer & explanation

Correct answer

Answer: (b)B.

46

Why this answer is correct

No. of students = 30

Average age = 15 years

⇒ Total age of 30 students = Average Age × No. of students = 15 × 30 = 450 years

Let the teacher’s age be ‘x’

⇒ New total age = 450 + x

New no. of persons = 31

⇒ New average = 15 + 1

⇒ (450+x)/31 = 16

⇒ 450 + x = 496

⇒ x = 46

Hence, teacher is 46 years old.

Question 16

BSPHCL Correspondence Clerk 2025• Test

Four-letter clusters have been given, out of which three are alike in some manner and one is different. Select the one that is different.

  1. AOption (a)

    TVZB

  2. BOption (b)

    OPRS

  3. COption (c)

    GIMO

  4. DOption (d)

    JLPR

View answer & explanation

Correct answer

Answer: (b)B.

OPRS

Why this answer is correct

The logic followed here is:

Logic: First letter + 2 = Second letter; Second letter + 4 = Third letter; Third letter + 2 = Fourth letter

  1. TVZB → T + 2 = V; V + 4 = Z; Z + 2 = B
  2. OPRS → O + 1 = P; P + 2 = R; R + 1 = S
  3. GIMO → G + 2 = I; I + 4 = M; M + 2 = O
  4. JLPR → J + 2 = L; L + 4 = P; P + 2 = R

Hence, 'OPRS' is the correct answer.

    22 years

  4. DOption (d)

    20 years

View answer & explanation

Correct answer

Answer: (c)C.

22 years

Why this answer is correct

Let the current age of the son be x years.

Thus the current age of the father is x + 24 years

Thus after two years,

x + 24 + 2 = 2(x + 2)

→ x + 26 = 2x + 4

→ x = 22

Thus the present age of his son is 22 years.
