Read carefully the following passage and answer the following questions:

One of the main objectives of accounting is to ascertain the profit or loss of a business enterprise at the end of an accounting period. There are two bases of ascertaining profit or loss, namely (1) Cash Basis, and (2) Accrual Basis.

Cash Basis Accounting: under this basis, incomes are not recorded unless they are received in cash. Similarly, expenses are recorded only when they are paid in cash. In other words, credit transactions are not recorded at all and are ignored till cash is actually received or paid for them. Thus profit is merely the excess of actual cash receipts in respect of sale of goods and other incomes over actual payments in respect of purchase of goods, expenses on wages, salary, rent etc. income or profit is calculated with the help of a receipt and payments account. This basis is useful for professional people like lawyers, doctors, chartered accountants etc.

Accrual Basis Accounting: under this basis, incomes are recorded when they are earned or ac-crued, irrespective of the fact whether cash is received or not, e.g., sales made on credit will be included in the total sales of the period. Similarly expenses are recorded when they are incurred or become sue and not when the cash is paid for them, e.g., rent due to the landlord but not paid will be treated as expense for the period when it is due and not in the period when it is paid. This makes it necessary to consider outstanding expanses, prepaid expenses, accrued incomes, incomes received in advance etc. for the preparation of financial statements. Under the Company's Act 1956, all companies are required to maintain their accounts according to accrual basis of account-ing.

Questions:

1. What is the main objective of accounting?

2. Name the Basis of Accounting.

3. What do you mean by Cash Basis of Accounting?

4. What do you mean by Accrual Basis of Accounting?

5. Name the users of Cash Basis of Accounting.

6. Name the users of Accrual Basis of Accounting.

7. Give the advantages of Accrual Basis of Accounting.

8. Give disadvantages of Cash Basis of Accounting? Chose the best alternate:

1. In accounts recording is made of a. Only financial transactions

b. Only non-financial transactions

c. Financial as well as non-financial transactions

d. Personal transactions of the Proprietor CASE STUDY-2:

Mr.Parkash a sole proprietor introduces some cash as his capital in the business. Here, Mr.Parkash and the business which he owes is treated as two separate entities. One entity i.e. Mr.Parkash is giving money to the other entity i.e. Business. It is worth mentioning here that we should record the transactions in the books of accounts from the point of view of business enterprise. So, in the business the amount of capital is a liability because the business has to pay back the amount of capital invested by Mr.Parkash. On the other hand, the amount of cash inc\vested by Mr. Parkash is an asset for the business. The business can use this amount for the purpose of business. This shows how the money introduced by the owner s treated as a liability for the business despite the fact that the business is owned by Mr. Parkash himself.

Q.1) Which accounting principle is highlighted in the above case? Explain in brief.

Q.2) State one limitation of the accounting principle identified above.

CASE STUDY-3:

Mr. Kabir a sole proprietor sold goods to Mr.Shashank on 25th march, 2014 for Rs.25,000 on credit. The amount was received on 16th april, 2014. In this case the sales must be recorded on 25th march 2014, although the amount was received on 16th april, 2014. The transaction of sales should be recorded as the revenue has been earned although the amount has not been received. Similarly, Mr.Shashank should also record the transaction of purchase in his books of accounts on 25th march, 2014 as goods have been purchased although the amount has not been paid on that day.

Q.1) Which fundamental accounting assumption is highlighted in the above

case?

Q.2) State one limitation of the accounting assumption identified above.

CASE STUDY-4:

M/s Ghanshyam Das Industries appointed a sales girl Priya. She is smart and impressive. Though her personality can have great positive influence on the business but her smartness cannot be measured in terms of money.

Q.1) Which accounting principle is highlighted in the above case? Explain in brief.

Q.2) State one limitation of the accounting principle identified above.

CASE STUDY-5:

During 18th Century, Mr.A used to purchase gold @ Re.1 per kg. During 19th Century, Mr.B (Grandson of Mr.A) used to purchase wheat @ Re.1 per kg. During 20th Century, Mr.C (Grandson of Mr.B) used to purchase salt @ Re.1 per kg. There are chances that Mr.D (Grandson of Mr.C) could purchase only grass @ Re.1 per kg by the end of 21st Century. These transactions in the books of accounts are recorded @ Re.1. But the items and their worth are different in different centuries.

Q.1) Which accounting principle is highlighted in the above case? Explain in brief.

Q.2) State one limitation of the accounting principle identified above.

CASE STUDY-6:

M/s Janki Das purchased Machinery for Rs. 9,70,000 for the business. In the books such machinery will be recorded at RS. 9,70,000 throughout its life, irrespective of its market value. Any subsequent increase or decrease in the market value of the

machinery should not be recorded in the books of accounts. It should also be noted that the total cost machinery i.e. Rs. 9,70,000 will be distributed to the useful life of machinery each year as depreciation and asset will appear at Book Value as against Market Value. Here book Value means Cost less Depreciation.

Q.1) Which accounting principle is highlighted in the above case?

Q.2) Also Explain the accounting principle identified above.
