Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(4, 2, 18)
(1, 7, 24)
(5, 4, ?)
(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: B
Explanation
The correct answer is option 2 i.e. 27.
The logic followed is:
Logic: (First no. + Second no.) × 3 = Third no.
(4, 2, 18) → (4 + 2) × 3 = 6 × 3 = 18
(1, 7, 24) → (1 + 7) × 3 = 8 × 3 = 24
(5, 4, ?) → (5 + 4) × 3 = 9 × 3 = 27
Thus, 27 will replace the question mark (?).
Hence, 27 is the correct answer.
