Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row: 16, 15, 35
Second row: 12, 18, 33
Third row: 8, 17, ?
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 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.
First row: 16, 15, 35 ⇒ (16 ÷ 4) + (16 + 15) ⇒ (4 + 31) = 35
Second row: 12, 18, 33 ⇒ (12 ÷ 4) + (12 + 18) ⇒ (3 + 30) = 33
Similarly, Third row: 8, 17, ? ⇒ (8 ÷ 4) + (8 + 17) ⇒ (2 + 25) = 27
