Question
From the given alternatives, select the one in which
the set of numbers is most like the set of numbers given in the question: (4, 6, 30)Solution
The logic follows here: (First Number + Second Number) multiplied by 3 equals the Third Number Given set: (4, 6, 30) → (4 + 6) x 3 = 10 x 3 = 30 Now, we check the options: Option A: (5, 8, 39) → (5 + 8) x 3 = 13 x 3 = 39 Option B: (2, 7, 21) → (2 + 7) x 3 = 9 x 3 = 27 Option C: (6, 9, 40) → (6 + 9) x 3 = 15 x 3 = 45 Option D: (3, 5, 20) → (3 + 5) x 3 = 8 x 3 = 24
