First row: 15, 3, 252
Second row: 11, 5, 246
Third row: 9, 6, ?
Logic: 'Row wise'
First row → Third no. = [(First no.)2 + (Second no.)3]
The first row (15, 3, 252) →
⇒ [(15)2 + (3)3]
⇒ (225 + 27) = 252
The second row (11, 5, 246) →
⇒ [(11)2 + (5)3]
⇒ (121 + 125) = 246
Similarly, for the third row (9, 6, ?) →
⇒ [(9)2 + (6)3]
⇒ (81 + 216) = 297
Here, the question mark is replaced by '297'.
Hence, the correct answer is "Option (4)".
