जर 2 × 8 = 4, 3 × 15 = 5 आणि 4 × 32 = 8, तर 5 × ? = 7.

The correct answer is Option B (35).

Key Points:
• This is a mathematical operations puzzle where standard symbols have hidden artificial meanings.
• Look at the pattern given as A × B = C.
• 2 × 8 = 4 -> Logic: 8 ÷ 2 = 4.
• 3 × 15 = 5 -> Logic: 15 ÷ 3 = 5.
• 4 × 32 = 8 -> Logic: 32 ÷ 4 = 8.
• The hidden rule is that the multiplication symbol (×) actually denotes dividing the second number by the first number (B ÷ A).
• Applying this to the question: 5 × ? = 7
• Therefore, ? ÷ 5 = 7 ⇒ ? = 7 × 5 = 35.
• Key Takeaway: Identify the hidden operation behind the symbol. Here, A × B actually means B / A.
