Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(6, 8, 11)
(2, 1, 2)
(6, 7, ?)
(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. 10.
Logic: (First number + Second number) - (First number ÷ 2) = Third number
(6, 8, 11) → (6 + 8) - (6 ÷ 2) = 14 - 3 = 11
(2, 1, 2) → (2 + 1) - (2 ÷ 2) = 3 - 1 = 2
Similarly, (6, 7, ?) → (6 + 7) - (6 ÷ 2) = 13 - 3 = 10
