Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(3, 9, 2)
(8, 6, 8)
(5, 3, ?)
(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: C
Explanation
The correct answer is option 3 i.e. 10.
Logic: (Second number × Third number) ÷ 6 = First number
(3, 9, 2) → (9 × 2) ÷ 6 = 18 ÷ 6 = 3
(8, 6, 8) → (6 × 8) ÷ 6 = 48 ÷ 6 = 8
(5, 3, ?) → ((3 × ?) ÷ 6 = 5
⇒ 30 ÷ 3 = 10
Thus, (5, 3, 10).
Hence, the correct answer is 10.
