Alternatively you can givea I Owe You voucher, but it is a better Internal Control System to pass this entry.

C) Now, this expenditure of 900$ should be accounted at the rate prevailing on the date of transactions, but, you can use an approximate rate. As there is no info in your question, we can ignore that rate and account the expenses in proportionate way - i.e. (50000 X 900$) / 1000$, hence, 45000

Shiva

ya shiva is absolutely correct .

 But in some organisations they take an average conversion rate for the whole month , you can debit the expense using that conversion rate  which is allowed as per AS 11 .

at closure of accounts whether monthly, quartely , half yearly or annually this FC should be reinstated at balance sheet date . Profit / loss should be accounted for

Yes, the P&L items, especially incomes-expenses are accounted on average rate..

Rest all entries are correct...

yaa agree with above entry by shiva
