View answer & explanation

Correct answer

Answer: (c)C.

21

Why this answer is correct

Given : 47 + 10 × 3 - 32 ÷ 8 = ? 

According to the question, after replacing the signs :

‘+’ and ‘-’ are interchanged 

So,​​

47 - 10 × 3 + 32 ÷ 8 = ?

47 - 10 × 3 + 4 = ?

47 + 4 - 30 = ?

51 - 30 = ?

21 = ?

Hence, "21" is the correct answer.

Why this answer is correct

Given equation:

42 K 1 R 14 Q 30 R 12 Q 28 P 110

Decoding the given information

LetterDenotes
P+
Q×
R÷
K-

 

Substituting the letters with the operations:

42 - 1 ÷14 × 30 ÷ 12 × 28 + 110

BODMAS Rule:

Solving the equation using BODMAS rule

42 - 1 ÷14 × 30 ÷ 12 × 28 + 110

= 42 - 0.0714 × 30 ÷ 12 × 28 + 110

= 42 - 0.0714 × 2.5 × 28 + 110

= 42 - 0.1785 × 28 + 110

= 42 - 5 + 110

= 152 - 5

= 147

Hence, the correct answer is "147".

View answer & explanation

Correct answer

Answer: (d)D.

Four

Why this answer is correct

Five bottles – P, Q, R, S, T

  1. Bottle S is larger than two bottles as well as smaller than two bottles.

….. > ….. > S > ….. > …...

  1. Bottle R is larger than only one bottle.

….. > ….. > S > R > …...

  1. Bottle Q is smaller than P but larger than S.

P > Q > S > R > …...

Thus bottle T is the smallest.

P > Q > S > R > T

Hence, four bottles are larger than bottle T.

Question 7

BSPHCL Correspondence Clerk 2025• Test

Refer to the given number and symbol series and answer the question that follows. Counting to be done from left to right only.

(Left) 2 & % 4 6 @ & 3 Ω 9 # 1 * 8 £ 6 1 7 # (Right)

How many such symbols are there, each of which is immediately preceded by an even number and also immediately followed by an even number?

  1. AOption (a)

    None

  2. BOption (b)

    One

  3. COption (c)

    Two

  4. DOption (d)

View answer & explanation

Correct answer

Answer: (b)B.

One

Why this answer is correct

Given: (Left) 2 & % 4 6 @ & 3 Ω 9 # 1 * 8 £ 6 1 7 # (Right)

Here, We need to find the numbers that are immediately preceded by a symbol and also immediately followed by a symbol.

Required pattern: Even Number - Symbol - Even Number

(Left) 2 & % 4 6 @ & 3 Ω 9 # 1 * 8 £ 6 1 7 # (Right)

So, there is only one such pair in the series '8 £ 6'.

Hence, the correct answer is "Option 2".

Question 8

BSPHCL Correspondence Clerk 2025• Test

Vikas ranks 18th in a class of 49 students. What is his rank from the last ?

  1. AOption (a)

    19

  2. BOption (b)

    31

  3. COption (c)

    32

  4. DOption (d)

    33

View answer & explanation

Correct answer

Answer: (c)C.

32

Why this answer is correct

Vikas's rank from first = 18

Total number of students = Position from first + position from last - 1

49 = 18 + position from last - 1

49 = 17 + position from last 

49 - 17 = position from last

Position from last = 32

So, vikas's rank from last is 32

Hence, option 3 is the correct answer.
