Select the option in which the numbers are related in the same way as are the numbers of the following set.
(12, 14, 143)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (15, 19, 252).
The logic used here is:
(12, 14, 143)
(12 - 1) × (14 - 1) = 11 × 13 = 143
Option 1: (12, 18, 246)
(12 - 1) × (18 - 1) = 11 × 17 = 187
This does not follow the logic.
Option 2: (17, 12, 134)
(17 - 1) × (12 - 1) = 16 × 11 = 176
This does not follow the logic.
Option 3: (16, 10, 235)
(16 - 1) × (10 - 1) = 15 × 9 = 135
This does not follow the logic.
Option 4: (15, 19, 252)
(15 - 1) × (19 - 1) = 14 × 18 = 252
This follows the logic.
Hence, option 4 is the correct answer.
