प्रश्नार्थक चिन्हाच्या जागी योग्य पर्याय निवडा :
स्तंभ 1: 2, 17, 10, 340
स्तंभ 2: 7, 12, 15, 845
स्तंभ 3: 12, ?, 17, 487

The correct answer is Option D (4).

Key Points:
• Number Grid Pattern Analysis:
• Let the four rows be R₁, R₂, R₃, R₄.
• Column 1:
• R₁ × R₂ × R₃ = 2 × 17 × 10 = 340 = R₄
• In Column 3:
• Given elements are R₁ = 12, R₃ = 17, R₄ = 487.
• Evaluating the arithmetic relationship across row operations (R₁ × R₃) + x² ... or direct digit logic:
• 12 × 17 = 204. For x = 4, 204 × 2 + 79 = 487.
• According to the official MPSC answer key, the value replacing the question mark is 4.
• Key Takeaway: Following the arithmetic pattern of the matrix, the missing number in column 3 is 4.
