Given:

Investment of A = ₹7,000

Investment of B = ₹8,000

Investment of C = ₹12,000

B's share of profit = ₹3,200

Formula used:

B's share of profit = (B's investment / Total investment) × Total profit

Total investment = A's investment + B's investment + C's investment

Calculation:

Total investment = ₹7,000 + ₹8,000 + ₹12,000

⇒ Total investment = ₹27,000

B's share of profit = (₹8,000 / ₹27,000) × Total profit

⇒ ₹3,200 = (₹8,000 / ₹27,000) × Total profit

⇒ Total profit = ₹3,200 × (₹27,000 / ₹8,000)

⇒ Total profit = ₹10,800

∴ The correct answer is option (4).
