Produce a correct trial balance as at 31 October 2014.

We will compare the given trial balance entries with the normal balance of each account type:

• Assets and Expenses normally have Debit balances.
• Liabilities, Equity, and Revenue normally have Credit balances.

Based on this, the following accounts are on the wrong side in the original trial balance:

• Return inwards (Sales Returns): An expense/contra-revenue account, should be Debit. It is currently Credit K20,000.
• Opening Inventories: An asset account, should be Debit. It is currently Credit K60,000.
• Carriage inwards: An expense account, should be Debit. It is currently Credit K14,000.
• Carriage outwards: An expense account, should be Debit. It is currently Credit K17,000.
• Insurance costs: An expense account, should be Debit. It is currently Credit K25,000.
• Communication costs: An expense account, should be Debit. It is currently Credit K18,000.
• Motor vehicle repairs: An expense account, should be Debit. It is currently Credit K21,000.
