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) (91, 78, 104)(68, 55, 81)Solution
The average of the 2nd and 3rd number equals the 1st number.
(91, 78, 104) → (78 + 104) / 2 = 91
(68, 55, 81) → (55 + 81)/2 = 68
Now, checking the options:
Option A → (88, 72, 98) → (72 + 98) / 2 = 85
Option B → (45, 30, 60) → (30 + 60)/2 = 45
Option C → (58, 41, 73) → (41 + 73)/2 = 57
Option D → (78, 64, 90) → (64 + 90)/2 = 77
