Correct answer

Answer: (d)D.

LAZY

Why this answer is correct

Given word: EQUALIZATION

(1) ZONE → Can be formed as all the letters (Z, O, N, E) are present in the given word.

(2) LION → Can be formed as all the letters (L, I, O, N) are present in the given word.

**(**3) QUITE → Can be formed as all the letters (Q,U,I,T,E) are present in the given word.

(4) LAZY → Can not be formed as Y is not present in the given word.

Hence, the correct answer is "Option 4".

Question 152

SSC GD Constable 2026• General Intelligence and Reasoning

Identify the wrong number in the following series.

3, 6, 11, 18, 27, 39, 51

  1. AOption (a)

    18

  2. BOption (b)

    27

  3. COption (c)

    39

  4. DOption (d)

    51

View answer & explanation

Correct answer

Answer: (c)C.

39

Why this answer is correct

Logic followed here is,

3 + 3 = 6

6 + 5 = 11

11 + 7 = 18

18 + 9 = 27

27 + 11 = 38 ≠ 39

38 + 13 = 51

Hence, the correct answer is “Option 3”.

Question 153

SSC GD Constable 2026• General Intelligence and Reasoning

Two pipes can fill a tank in 12 hours and 18 hours, respectively. A third pipe can empty the tank in 9 hours. If all three pipes are opened together, in how much time will the tank be filled?

  1. AOption (a)

    18 hours

  2. BOption (b)

    36 hours

  3. COption (c)

    24 hours

  4. DOption (d)

    12 hours

View answer & explanation

Correct answer

Answer: (b)B.

36 hours

Why this answer is correct

Given:

Two pipes can fill a tank in 12 hours and 18 hours.

A third pipe can empty the tank in 9 hours. 

Formula used:

Time = Total Capacity ÷ Net Efficiency

Calculation:

Let pipes are A, B and C.

Efficiency of Pipe A = 36 ÷ 12 = 3 units/hr

Efficiency of Pipe B = 36 ÷ 18 = 2 units/hr

Efficiency of Pipe C = 36 ÷ 9 = 4 units/hr (Since it empties the tank, its efficiency will be taken as negative).

Net Efficiency = Efficiency of A + Efficiency of B − Efficiency of C

Net Efficiency = 3 + 2 − 4 = 1 unit/hr

Time = Total Capacity ÷ Net Efficiency

Time = 36 ÷ 1 = 36 hours

Hence, the correct answer is “Option 2”.

Select the option that is related to the fifth letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and fourth letter-number cluster is related to third letter-number cluster. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Select the option that is related to the first number in the same way as the fourth number is related to the third number and sixth number is related to fifth number. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

8149 : ? :: 5625 : 5584 :: 309 : 268

  1. AOption (a)

    8104

    8106

  4. DOption (d)

    8108

View answer & explanation

Correct answer

Answer: (d)D.

8108

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number − 41

For the second pair 5625 : 5584

⇒ 5625 − 41 = 5584.

For the third pair 309 : 268

⇒ 309 − 41 = 268.

Applying the same logic to the first pair

8149 : ?

⇒ 8149 − 41 = 8108.

Hence, the correct answer is 'Option 4'.
