- The Machinery account is credited with the original cost of the machinery, which is Rs. 8,000.

**2. Record the Loss on Sale of Machinery**

Since the machinery was sold at a loss, we need to record the loss separately in the books of accounts. We will debit the Loss on Sale of Machinery account and credit the Machinery account to account for the reduction in value.

- The Machinery account is credited with the reduced value of the machinery, which is Rs. 3,000.

**3. Record the Cash Received**

Finally, we need to record the cash received from the sale of machinery. We will debit the Cash account and credit the Sales account to reflect the inflow of cash.

**Journal Entry:**
