Select the set in which the numbers are related in the same way as the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their 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)
(21, 34, 76) (39, 26, 104)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (28, 23, 79).
The logic used here is:
(21, 34, 76)
34 + (21 × 2) = 34 + 42 = 76
(39, 26, 104)
26 + (39 × 2) = 26 + 78 = 104
Similarly,
(28, 23, 79)
23 + (28 × 2) = 23 + 56 = 79
Hence, (28, 23, 79) is the correct answer.
