Question
Select the option in which the numbers shared the same
relationship in set as that shared by the numbers in the given 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) (44, 36, 28) (32, 44, 56)Solution
The average of first and third number is the second number. (44, 36, 28) → (44 + 28) /2 = 36 (32, 44, 56) → (32 + 56) /2 = 44 (45, 36, 55) → (45 + 55) /2 = 50 (27, 15, 13)  → (27 + 13) /2 = 20 (42, 34, 26) → (42 + 26) /2 = 34 (68, 36, 10)  → (68 + 10) /2 = 39
