Select the set in which the numbers are related in the same way as are the numbers of 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.)
(22, 81, 13)
(16, 1, 5)
22 - √81 = 22 - 9 = 13 16 - √1 = 16 - 1 = 5 Similarly, 12 - √49 = 12 - 7 = 5.
