Analogy (SSC CGL 2019 Tier 1)

1. Select the option in which the numbers are related in the same way as are the numbers in the given set. [SSC CGL 03/03/2020 (Morning)]

(269, 278, 296)

(a) (419, 430, 448)
(b) (109, 118, 128)
(c) (313, 322, 340)
(d) (577, 586, 598)

Correct Answer: (c) (313, 322, 340)

Solution:Here, the logic: +9, +18
1st number + ‘9’ → 2nd number
2nd number + ‘18’ → 3rd number (‘18’ is double of ‘9’)
269 + 9 = 278
278 + 18 = 296
Now only (313, 322, 340) is following the given pattern.

Solution:The pattern:

By observing, we find that only (12, 19, 40) satisfies the above pattern.

4. Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number. [SSC CGL 05/03/2020 (Morning)]

72 : 108 :: 84 : ? :: 102 : 153

(a) 126
(b) 144
(c) 117
(d) 135

Correct Answer: (a) 126

Solution:Following pattern is followed
72 : 108 102 : 153
12 × 6 = 72 17 × 6 = 102
12 × 9 = 108 17 × 9 = 153
Similarly,
14 × 6 = 84
14 × 9 = 126

5. Select the option in which the numbers are related in the same way as are the numbers in the given set. [SSC CGL 05/03/2020 (Afternoon)]

(7, 98, 196)

(a) (20, 267, 520)
(b) (11, 154, 308)
(c) (18, 185, 360)
(d) (15, 190, 380)

Correct Answer: (b) (11, 154, 308)

Solution:The pattern followed by the given set (7, 98, 196) is
7 × 14 = 98
7 × 28 = 196
After observing all the options, we find that set (11, 154, 308) follows the given pattern.
11 × 14 = 154
11 × 28 = 308

6. 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 CGL 05/03/2020 (Evening)]

(13, 109 :: 24 : ?)

(a) 201
(b) 194
(c) 216
(d) 197

Correct Answer: (d) 197

Solution:The pattern: (1st number × 8) + 5 = 2nd number
(13 × 8) + 5 = 104 + 5 = 109
similarly, (24 × 8) + 5 = 192 + 5 = 197

7. Select the option in which the numbers are related in the same way as are the numbers in the given set. [SSC CGL 05/03/2020 (Evening)]

(8, 7, 407)

(a) (12, 8, 555)
(b) (10, 8, 576)
(c) (11, 12, 450)
(d) (9, 6, 297)

Correct Answer: (d) (9, 6, 297)

Solution:

64 (8²) + 343 (7³) = 407

Similarly,

8. Select the option in which the numbers are related in the same way as are the numbers in the given set. [SSC CGL 06/03/2020 (Afternoon)]

(343, 98, 21)

(a) (1331, 242, 33)
(b) (512, 126, 27)
(c) (1728, 288, 24)
(d) (217, 72, 18)

Correct Answer: (a) (1331, 242, 33)

Solution:(343, 98, 21)
→ (343 → 7³, 98 → 7² × 2, 21 → 7 × 3)
(1331, 242, 33)
→ (1331 → 11³, 242 → 11² × 2, 33 → 11 × 3)

9. Select the option in which the numbers are related in the same way as are the numbers in the given set. [SSC CGL 06/03/2020 (Evening)]

(14, 18, 277)

(d) (12, 32, 320)c

Correct Answer: (c) (20, 22, 521)

Solution:(14, 18, 277)
→ 14² + (18 ÷ 2)² → 277
Similarly, (20, 22, 521)
→ 20² + (22 ÷ 2)² → 521

10. 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 CGL 07/03/2020 (Afternoon)]
