Analogy (SSC CHSL 2020 Tier 1)

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. [SSC CHSL 12/04/2021 (Morning)]

25 : 750 :: 30 : ?

(a) 1110
(b) 1275
(c) 1625
(d) 1050

Correct Answer: (d) 1050

Solution:Logic
1st no. × (1st no.+5) = 2nd no.
25 × (25+5) = 750
Similarly, 30 : 30(30 + 5) : 30 : 1050

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. [SSC CHSL 13/04/2021 (Afternoon)]

(12, 36, 132)

(a) (15, 45, 165)
(b) (19, 57, 209)
(c) (22, 66, 242)
(d) (18, 54, 196)

Correct Answer: (d) (18, 54, 196)

Solution:Logic
1st no. + 3rd no. = 4 × (2nd no.)
(12, 36, 132) → 12+132 = 4 × 36 = 144

Now,
(15, 45, 165) → 15+165 = 4×45=180
(19, 57, 209) → 19+209 = 4×57=228
(22, 66, 242) → 22+242 = 4×66=264
(18, 54, 196) → 18+196 = 4×54=216
214 ≠ 216

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

(11, 72, 264)

(a) (20, 77, 480)
(b) (16, 88, 456)
(c) (19, 75, 456)
(d) (17, 74, 338)

Correct Answer: (b) (16, 88, 456)

Solution:Logic:
2 × (1st no. × 2nd no.) = 3rd no.
(11, 12, 264): 2 × (11 × 12) = 264
Similarly, (16, 18, 576): 2 × (11 × 12) = 264

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: [SSC CHSL 13/04/2021 (Evening)]

Doctor : Cardiologist

(a) Nurse : Injection
(b) Teacher : Education
(c) Engineer : Chemical Engineer
(d) Surgeon : Operation

Correct Answer: (c) Engineer : Chemical Engineer

Solution:A Cardiologist is a type of doctor. Similarly, A chemical engineer is a type of engineer.

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. [SSC CHSL 15/04/2021 (Morning)]

6 : 85

(a) 7 : 112
(b) 9 : 181
(c) 5 : 50
(d) 8 : 114

Correct Answer: (b) 9 : 181

Solution:Logic:
2nd term/ 1st term = rem.(+1)
6 : 85 → 85 ÷ 6 = rem.(+1)
Similarly, 9 : 181 → 181 ÷ 9 = rem.(+1)

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

(19, 53, 215)

(a) (13, 35, 143)
(b) (15, 49, 199)
(c) (18, 50, 230)
(d) (17, 47, 112)

Correct Answer: (a) (13, 35, 143)

Solution:Logic:
(1st number + 2nd number) × 3 - 1 = 3rd no.
(19, 53, 215): (19 + 53) × 3 - 1 = (72 × 3) - 1 = 215
similarly,
(13, 35, 143): (13 + 35) × 3 - 1 = (48 × 3) - 1 = 143

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. [SSC CHSL 16/04/2021 (Morning)]

(165, 16, 91)

(a) (76, 11, 45)
(b) (57, 9, 24)
(c) (99, 14, 97)
(d) (85, 13, 59)

Correct Answer: (d) (85, 13, 59)

Solution:Logic:
1st number + 3rd number = (2nd number)²
(165, 16, 91): 165 + 91 = 16² = 256
Similarly,
(76, 11, 45): 76 + 45 = 11² = 121
(57, 9, 24): 57 + 24 = 9² = 81
(99, 14, 97): 99 + 97 = 14² = 196
(85, 13, 59): 85 + 59 = 169, 13² = 169

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

(6, 9, 18)

(a) (10, 15, 50)
(b) (8, 12, 30)
(c) (12, 18, 82)
(d) (9, 13, 40)

Correct Answer: (a) (10, 15, 50)

Solution:Logic → [

If n = 10 then (

and (

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

9 : 50

(a) 8 : 42
(b) 11 : 63
(c) 5 : 16
(d) 13 : 98

Correct Answer: (d) 13 : 98

Solution: Logic → (1st number + 1)² ÷ 2 = 2nd number
9 : 50 → (9 + 1)² ÷ 2 = 100 ÷ 2 = 50
Similarly,
13 : 98 → (13 + 1)² ÷ 2 = 196 ÷ 2 = 98

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

(650, 645, 410)

(a) (558, 256, 356)
(b) (550, 402, 135)
(c) (440, 229, 422)
(d) (751, 396, 544)

Correct Answer: (c) (440, 229, 422)

Solution:Logic → 2 × (1st number - 2nd number) = 3rd number
(850, 645, 410) → 2 × (850 - 645) = 410
Similarly
(440, 229, 422) → 2 × (440 - 229) = 422
