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.)
(54, 32, 66)
(49, 31, 54)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (39, 18, 63).
Here the Logic is : Third Number = ( First Number - Second Number ) x 3
⇒(54, 32, 66)
54 - 32 x 3 = 22 x 3 = 66
⇒(49, 31, 54)
49 - 31 x 3 = 18 x 3 = 54
Similarly,
For (39, 18, 63)
39 - 18 x 3 = 21 x 3 = 63
Hence, (39, 18, 63) is the correct answer.
