Question
Select the option in which the numbers share 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., Operation 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) (17, 29, 92)Solution
The logic is: Third number = (First number + Second number) x 2 In (17, 29, 92), Third number = (17 + 29) x 2 = 46 x 2 = 92. Checking options: A) (7 + 10) x 2 = 17 x 2 = 34, matches. B) (13 + 21) x 2 = 34 x 2 = 68, matches. C) (9 + 14) x 2 = 23 x 2 = 46 which is not equal to 50. D) (15 + 20) x 2 = 35 x 2 = 70, matches.
