Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(26, 38, 128)
(42, 19, 122)
(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.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (33, 23, 112).
Logic: First number + Second number = Resultant number × 2 = Third number
(26, 38, 128): 38 + 26 = 64, 64 × 2 = 128
(42, 19, 122): 42 + 19 = 61, 61 × 2 = 122
Similarly, (33, 23, 112): 33 + 23 = 56, 56 × 2 = 112.
