Question
Study the given pattern carefully and select the number
that can replace the question mark (?) in it. (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) (9, 8, 15) (7, 16, 21) (5, 8, ?)Solution
The logic is: (9 + 8) - 2 = 17 - 2 = 15 (7 + 16) - 2 = 23 - 2 = 21 Similarly(5 + 8) - 2 = 13 - 2 = 11
