Question
Select the option in which the numbers share the same
relationship as that shared by the number in the set given below. Â (19, 42, 28) (11, 39, 33)Solution
The logic followed here is: (2nd number – 1st number) + 5 = 3rd number  (19, 42, 28) → (42 – 19) + 5 = 23 + 5 = 28 (11, 39, 33) → (39 – 11) + 5 = 28 + 5 = 33  By checking options, (25, 37, 19) → (37 – 25) + 5 = 12 + 5 = 17 ≠19  (21, 43, 28) → (43 – 21) + 5 = 22 + 5 = 27 ≠28  (20, 58, 43) → (58 – 20) + 5 = 38 + 5 = 43  (23, 55, 36) → (55 – 23) + 5 = 32 + 5 = 37 ≠36 Hence, correct answer is (C).
