Question
Select the set in which the numbers are related in the same
way as are the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - Operations on 13 such as adding/ subtracting/ multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed) (72, 58, 86)(55, 42, 68)Solution
The average of the 2nd and 3rd number equals the 1st number.
(72, 58, 86) → (58 + 86) / 2 = 72
(55, 42, 68) → (42 + 68)/2 = 55
Now, checking the options:
Option A → (64, 50, 78) → (50 + 78) / 2 = 64
Option B → (30, 26, 34) → (26 + 34)/2 = 30
Option C → (41, 73, 27) → (73 + 27)/2 = 50
Option D → (48, 32, 64) → (32 + 64)/2 = 48
