By Brahmagupta's rules: a fortune (positive) multiplied by a debt (negative) gives:
AA fortune
BA debt
CZero
DCannot be calculated
Answer & Solution
Correct answer: B. A debt
Positive × Negative = Negative (a debt). Example: (−3) × 4 = −12. Conceptually: if you take on 4 debts of ₹3 each, your total debt is ₹12. Brahmagupta's rules of integer arithmetic are still the rules we use 1300+ years later.
