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., 51 - Operations on 51 such as adding/ subtracting/ multiplying etc. to 51 can be performed. Breaking down 51 into 5 and 1 and then performing mathematical operations on 5 and 1 is not allowed) . (153, 164, 492)Solution
The logic followed here is: First number + 11 = Second number Second number X 3 = Third number (153, 164, 492) → 153 + 11 = 164; 164 x 3 = 492. 1) (108, 119, 357) → 108 + 11 = 119; 119 x 3 = 357. 2) (134, 145, 435) → 134 + 11 = 145; 145 x 3 = 435. 3) (115, 126, 378) → 115 + 11 = 126; 126 x 3 = 378. 3) (130, 141, 420) → 130 + 11 = 141; 141 x 3 = 423.
