1. Select the option that is related to the third number in the same way as the second number is related to the first number. [S.S.C CHSL 12/04/2021 (Morning)]

25 : 750 :: 30 : ?

Correct Answer: (d) 1050
Solution:

The pattern followed here is :

(a : b) → {a × (a + 5)} = b

(25 : 750) → {25 × (25 + 5)} ⇒ 25 × 30 = 750

Similarly,

(30 : ?) → {30 × (30 + 5)} ⇒ 30 × 35 = 1050

Hence, "1050" is the correct answer.

2. From the given options choose the one in which the set of numbers do not follow the same Logic/Rule/Relation as the numbers given in below set. [S.S.C CHSL 13/04/2021 (Afternoon)]

(12, 36, 132)

Correct Answer: (d) (18, 54, 196)
Solution:The pattern followed here is :

(a, b, c) → {a + c) ÷ 4} = b

(12, 36, 132) → {(12 + 132) ÷ 4} ⇒ 144 ÷ 4 = 36

But,

(18, 54, 196) → {(18 + 196) ÷ 4} ⇒ 214 ÷ 4 = 53.5 ≠ 54

Hence, "(18, 54, 196)" is the correct answer.

3. Select the option in which the numbers are related in the same way as are the numbers of the following set. [S.S.C CHSL 13/04/2021 (Evening)]

(11, 12, 264)

Correct Answer: (b) (16, 18, 576)
Solution:The pattern followed here is :

(a, b, c) → 2 × a × b = c

(11, 12, 264) → 2 × 11 × 12 = 264

Similarly,

(16, 18, 576) → 2 × 16 × 18 = 576

Hence, "(16, 18, 576)" is the correct answer.

4. Select the word-pair in which the two words are related in the same way as are the two words in the following word-pair: [S.S.C CHSL 13/04/2021 (Evening)]

Doctor : Cardiologist

Correct Answer: (c) Engineer : Chemical Engineer
Solution:The logic followed here is :

A Cardiologist is a type of doctor.

Similarly,

A chemical engineer is a type of engineer.

Hence, "Engineer : Chemical Engineer" is the correct answer.

5. Select the number-pair in which the two numbers are related in the same way as the two numbers of the following number-pair. [S.S.C CHSL 15/04/2021 (Morning)]

6 : 85

Correct Answer: (b) 9 : 181
Solution:The pattern followed here is :

(a : b) → b ÷ a = reminder should be (+1)

(6 : 85) → 85 ÷ 6 = reminder (+1)
Similarly,

(9 : 181) → 181 ÷ 9 = reminder (+1)

Hence, "(9 : 181)" is the correct answer.

6. Select the set in which the numbers are related in the same way as are the numbers of the following set. [S.S.C CHSL 15/04/2021 (Morning)]

(19, 53, 215)

Correct Answer: (a) (13, 35, 143)
Solution:The pattern followed here is :

(a, b, c) → [{(a + b) × 3} - 1] = c

(19, 53, 215) → [{(19 + 53) × 3} - 1] ⇒ {(72 × 3) - 1} ⇒ 216 - 1 = 215

Similarly,

(13, 35, 143) → [{(13 + 35) × 3} - 1] ⇒ {(48 × 3) - 1} ⇒ 144 - 1 = 143

Hence, "(13, 35, 143)" is the correct answer.

7. From the given options choose the one in which the set of numbers do not follow the same Logic/Rule/Relation as the numbers given in below set. [S.S.C CHSL 16/04/2021 (Morning)]

(165, 16, 91)

Correct Answer: (d) (85, 13, 59)
Solution:The pattern followed here is :

(a, b, c) → √(a + c) = b

(165, 16, 91) → √(165 + 91) ⇒ √256 = 16

Similarly,

(85, 13, 59) → √(85 + 59) ⇒ √144 = 12 ≠ 13

Hence, "(85, 13, 59)" is the correct answer.

8. Select the option in which the numbers are related in the same way as are the numbers of the following set. [S.S.C CHSL 16/04/2021 (Morning)]

(6, 9, 54)

Correct Answer: (a) (10, 15, 150)
Solution:The pattern followed here is :

(a, b, c) → a × b = c

(6, 9, 54) → 6 × 9 = 54

Similarly,

(10, 15, 150) → 10 × 15 = 150

Hence, "(10, 15, 150)" is the correct answer.

9. Select the option in which the numbers share the same relationship as that shared by the given pair of numbers. [S.S.C CHSL 16/04/2021 (Morning)]

9 : 50

Correct Answer: (d) 13 : 98
Solution:The pattern followed here is :

(a : b) → {(a + 1)² ÷ 2} = b

(9 : 50) → {(9 + 1)² ÷ 2} ⇒ 100 ÷ 2 = 50

Similarly,

(13 : 98) → {(13 + 1)² ÷ 2} ⇒ 196 ÷ 2 = 98

Hence, "(13 : 98)" is the correct answer.

10. Select the option in which the numbers share the same relationship as that shared by the numbers in the given set. [S.S.C CHSL 16/04/2021 (Evening)]

(650, 645, 410)

Correct Answer: (c) (440, 229, 422)
Solution:The pattern followed here is :

(a, b, c) → {2 × (a - b)} = c

(850, 645, 410) → {2 × (850 - 645)} ⇒ 2 × 205 = 410

Similarly

(440, 229, 422) → {2 × (440 - 229)} ⇒ 2 × 211 = 422

Hence, "(440, 229, 422)" is the correct answer.
