A man buys a sofa set for ₹24,000. He spends ₹3,000 on repairs and sells it for ₹30,000.

Step 1: First transaction

• Cost price (CP) = ₹24,000

• Repairs = ₹3,000

• Total cost = ₹24,000 + ₹3,000 = ₹27,000

• Selling price (SP) = ₹30,000

Profit in first transaction:
Profit = SP − Total CP = ₹30,000 − ₹27,000 = ₹3,000

Step 2: Second transaction

• Buys back for SP = ₹28,000

• Sells at a loss of ₹1,200

Selling price of second transaction:
SP = 28,000 − 1,200 = ₹26,800

Loss in second transaction:
Loss = 28,000 − 26,800 = ₹1,200

Step 3: Overall profit

Overall profit = Profit from first transaction − Loss from second transaction

Overall profit = ₹3,000 − ₹1,200 = ₹1,800

✅ Answer: ₹1,800
