Which number should come in place of the question mark (?) in the following chart :
- A.
16
- B.
26
- C.
20
- D.
12
(Correct Answer)
Explanation
The logic is:
Column 1: 2 × 1 + 1 = 3
Column 2: 14 × 7 + 7 = 105
Similarly,
Column 3: ? × 9 + 9 = 117
=> ? × 9 = 117 – 9
=> ? × 9 = 108
=> ? = 108 ÷ 9
=> ? = 12
Hence, ‘12’ is the correct answer
