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. [35, 30, 100] [52, 24, 128]Solution
The pattern followed here is: The first number is multiplied by 2 and then it is added to the second number to get the third number. (35, 30, 100) → (35 X 2 + 30) = 100 (52, 24, 128) → (52 X 2 + 24) = 128 (41, 34, 130) → (41 X 2 + 34) = 116 (12, 14, 58) → (12 X 2 + 14) = 38 (34, 38, 122) → (34 X 2 + 38) = 106 (20, 45, 85) → (20 X 2 + 45) = 85
