Cash balance is $652,440

Explanation:

The cash balance is computed as:

Cash balance = Checking account balance + Cash Advance

                       = $651,600 + $840

                        = $652,440

Future plant expansion would not be included in cash balance because it is restricted to use as it is kept for future expansion.

Advance to executive will not be included in the cash balance because it is an advance which is receivable in future.

Refundable deposit will also not be included as it is refundable in nature and act as receivable.

Treasury bill is not included as it represent temporary investment.
