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 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)
(15, 9, 4) (7, 2, 3)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (19, 13, 4).
(15, 9, 4) = 9 + 4 = 13, 13 + 2 = 15
(7, 2, 3) = 3 + 2 = 5, 5 + 2 = 7
Similarly, (19, 13, 4) = 13 + 4 = 17, 17 + 2 = 19
