View answer & explanation

Correct answer

Answer: (d)D.

11 : 143

Why this answer is correct

The logic followed here is:

Logic: Number × consecutive prime number.

For,  7 : 77.

⇒ 7 × 11 = 77

 Apply the same logic to each of the given options.

Option 1: 9 : 95

9 × 11 = 99, which is not equal to 95. Therefore, this option is incorrect.

Option 2: 13 : 91

13 × 17 = 221,  which is not equal to 91. Therefore, this option is correct. 

Option 3: 11 : 123

11 × 13 = 143, which is not equal to 123. Therefore, this option is incorrect.

Option 4: 11 : 143

11 × 13 = 143. Therefore, this option is also correct. 

 

Thus, the pair 11 : 143 is similar to 7 : 77.

Hence, the answer is "Option 4".

Question 16

CISF Tradesman 2023• Ability to observe and distinguish patterns

12 : 60

Which of the following pair is similar to the above expression?

  1. AOption (a)

  4. DOption (d)

    14 : 70

View answer & explanation

Correct answer

Answer: (d)D.

14 : 70

Why this answer is correct

The logic followed here is:

Logic: 1st number × 5 = 2nd number. 

For, 12 : 60

⇒12 × 5 = 60.

Let's check options one by one.

Option 1) 15 : 91

⇒15 × 5 = 90 ≠ 91.

Doesn't follow the pattern.

Option 2) 17 : 119

⇒17 × 5 = 85 ≠ 119.

Doesn't follow the pattern.

Option 3) 13 : 78

⇒13 × 5 = 65 ≠ 78.

Doesn't follow the pattern.

Option 4) 14 : 70

⇒14 × 5 = 70.

Do follow the pattern.

Hence, the correct answer is "Option 4".

View answer & explanation

Correct answer

Answer: (a)A.

2

Why this answer is correct

The logic followed here is:

Logic: Edges of outer shape + 1 edge = Inner shape.

 → Outer shape has 5 sides + 1 = Inner shape has 6 sides.

 → Outer shape has 4 sides - 1 = Inner shape has 3 sides. Doesn't follow the pattern.

 → Outer shape has 3 sides + 1 = Inner shape has 4 sides.

 → Outer shape has 4 sides + 1 = Inner shape has 5 sides.

 → Outer shape has 5 sides + 1 = Inner shape has 6 sides.

Thus, Figure 2 doesn't follow the pattern.

Hence, the correct answer is "Option 1".

Question 18
