Which option would replace the question mark in the given figure?
| 7 | 21 | 8 |
| 17 | ? | 5 |
| 12 | 1 | 23 |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 14
In a number grid the rule is looked for along the complete rows and columns. Here every row and every column adds up to 36.
Row 1: \(7+21+8=36\); row 3: \(12+1+23=36\)
Column 1: \(7+17+12=36\); column 3: \(8+5+23=36\)
Row 2: \(17+?+5=36\), so \(?=36-22=14\)
The middle column confirms it: \(21+14+1=36\).
