Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(3, 5, 6)
(5, 12, 15)
(9, 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. (9, 4, 11).
Logic : (First number + Second number) - 2 = Third number
(3, 5, 6) ⇒ 3 + 5 - 2 = 8 - 2 = 6
(5, 12, 15) ⇒ 5 + 12 - 2 = 17 - 2 = 15
Similarly,
(9, 4, ?) ⇒ 9 + 4 - 2 = 13 - 2 = 11
Hence, the correct answer is (9, 4, 11).
