Question
Select the set in which the numbers are related in the
same way as are the numbers of the following sets. (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/deleting/multiplying, etc. can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (12, 51, 5) (5, 36, 7)Solution
12 + 5 = 17 x 3 = 51 5 + 7 = 12 x 3 = 36 Similarly, 11 + 6 = 17 x 3 = 51
