38 is related to 80 following a certain logic. Following the same logic, 42 is related to 88. To which of the following is 29 related, following the same logic?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 62.
Logic: (1st number × 2) + 4 = 2nd number
38 : 80 ⇒ (38 × 2) + 4 = 76 + 4 = 80
42 : 88 ⇒ (42 × 2) + 4 = 84 + 4 = 88
Similarly, 29 ∶ ? ⇒ (29 × 2) + 4 = 58 + 4 = 62
