The Directors of Lolipop Ltd are currently considering two mutually exclusive investment projects. Both projects are concerned with the purchase of new plant. The following data are available for each project

Project A Project B

$'m

Cost( immediate outlay ) 100 60

Expected annual net profit (loss)

Year 1 29 18

Year 2 (1) (2)

Year 3 2 4

Estimated residual value of the plant 7 6

The minimum expected return by the shareholders is 10%. the Industrial average cost of capital is 12%. The company uses the straight line method of depreciation for all non-current (fixed )assets when calculating profit. Neither project would increase the working capital of the business. The business has sufficient funds to meet all capital expenditure requirements . The company expects to pay a total constant dividend of $ million per year for the next three ( 3) years.

Required

a) Calculate for each project

1. Accounting Rate of Return

2. The PayBack period

3. The NPV

4. The approximate IRR

Advise the directors which project should be undertaken

b) State which method of investment appraisal in (a) above you consider to b e most appropriate for calculating investment projects and why

c) Explain three (3) factors that may affect the dividend policy of Lolipop Ltd

Devise a procedure for the separation and purification of the mixture containing 0.25g benzoic acid, 0.20g benzil, 0.05 p-dichlorobenzene.

Available reagents: 1M NaOH, 1M HCI, 1M NaHCO3, 6 M NaOH, 6 M HCI, saturated solution of NaCl, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexane, toluene, ethyl acetate, anhydrous sodium sulfate.

Suppose that you are the manager of a local deli. Give an example of each of the following decisions that you might have to make and identify three factors that would be relevant to each decision:

1. Special order.
2. Make or buy.
3. Keep or drop.

1.  XYZ Company, a manufacturer of computer peripheries, assembles a particular product line at a wholly owned facility in Singapore. The product is designed at XYZ’s headquarters in the United States, but the different components used in the assembly process are manufactured throughout Asia and shipped to Singapore for final assembly. Some of the components are manufactured in multiple locations, so the customer can actually designate where XYZ should source the components. The final product is assembled in Singapore and then shipped via Emery Freight to customers throughout Asia. XYZ Singapore does not buy any components from the United States, but it invoices all of the components purchased from Asian suppliers in U.S. dollars. In addition, it sells the product to Asian customers in U.S. dollars. However, all of its expenses in Singapore are paid in Singapore dollars. Most of the key marketing decisions are made by the U.S. marketing staff, although the Singapore staff acts as a liaison with Emery Freight personnel and deals with the local workers, most of whom come from Sri Lanka on short-term work visas.

     XYZ prefers to translate the results of their Singapore subsidiary into dollars using the current rate method. What is the advantage to XYZ of using the current rate method? As their auditor, what do you think of their decision? If their decision is wrong and they should be using the temporal method, is it possible for them to change?

In a drag race, the position of a car as a function of time is given by x=bt2, with b = 2.045m/s2 . In an attempt to determine the car's velocity midway down a 400-m track, two observers stand at the 165-m and 235-m marks and note the time when the car passes.What value do the two observers compute for the car's velocity over this 70m stretch?

Monochlorobenzene (C6H5Cl) is produced commercially by the direct catalytic chlorination of benzene (C6H6). In the process, dichlorobenzene(C6H4Cl2) is generated as a coproduct.

?6?6 + ??2 → ?6?5?? + ??? ?6?5?? + ??2 → ?6?4??2 + ???

Given that the molar ratio of benzene to chlorine in the feed is 5 to 1; and the feed contains only benzene and chlorine. Chlorine is the limiting reactant and completely consumed in the reaction. The fractional yield of C6H5Cl is 0.875

. a. Take a basis of 100 mol C6H5Cl produced, draw and label a flowchart. Do a degree of freedom analysis based on atomic species balances.

b. Calculate the amount of feed and product components of the reactor using the atomic species balances. Present the calculated values in a table to prove that the total mass to the reactor is equal to the total mass out from the reactor (mass conservation).

c. Calculate the percentage conversion of C6H6. The value that you have calculated should be low. Why do you think the reactor would be designed for low conversion? What additional processing steps are likely to take place downstream of the reactor in order to improve the conversion?
