^Is this for the 2009 sem 1 exam?
If so:
2. The $225 are the costs that go into producing the product (or the direct costs). But to get the total cost we have to allocate some of the overhead, with the cost driver being hours of labour. 475,000/20,000 gives us the cost per hour of $23.75. And one product uses 27 hours, giving overhead allocation of $641.25 to each product. Add on the direct costs of the product and we get $866.25, hence D.
6. This basically involves identifying which of the cash flows are operating. The only inflow that is operating is rent received, and the only operating outflow is rent expense. The others are investing or financing. So if we receive 2000 and pay 3000, our net cash flow from operating is -1,000; hence C. The opening balance that they give you is irrelevant, because we are looking at net cash flow, not a balance.
8. Think A=L+OE. If assets increase, either L or OE has to increase (or another asset decrease). Our assets increase by 200,000+140,000=340,000; our liabilities increase by 140,000+120,000=260,000; and our OE has increased by 40,000-100,000=-60,000. So plugging that into out equation gives:
340,000=260,000-60,000 + Profit
Profit=140,000 hence A. This is the value what we need to add on make the equation hold true.
