What will come at the place of the question mark? 4 9 2
3 5 7
8 1 ?
6
This is the classic 3×3 magic square in which every row, column, and diagonal adds up to the same number.
Row 1: \(4 + 9 + 2 = 15\). Row 2: \(3 + 5 + 7 = 15\). So the magic sum is 15.
For Row 3: \(8 + 1 + ? = 15 \;\Rightarrow\; ? = 6\).
Hence the missing number is 6 — option (1).
