How do you know if a currency is overvalued or undervalued

I have 2 questions with answers that don't seem to be matching:

If real exchange rate qUS/qforeign is more than 1, then US currency is said to be undervalued correct?

Question 1: You are given the following information. The current dollar-pound exchange rate is $2 per pound. A U.S basket that costs $100 would cost $120 in the United Kingdom. For the next year, the Fed is predicted to keep U.S. inflation at 2% and the Bank of England is predicted to keep U.K inflation at 3%. The speed of convergence to absolute PPP is 15% per year.

Answer: The dollar is overvalued because real exchange rate is 1.29 (=$120/$100). shouldn't it be undervalued since it is more than 1?

Question 2:

Suppose a new car costs 210,000 Mexican pesos in Mexico, while the same car costs $19,500 in the United States. The nominal exchange rat is currently at E$/Peso = $.10/Peso. If we assume PPP to hold, is the dollar under or overvalued? If so, by how much?

qUS/qPESO= (210,000)*(.1)/(19,500)=1.0769. The answer is that the US is overvalued as well.

Why is it that qUS/qForeign are both more than one but US currency is overvalued in one of them but undervalued by another. Is the answer wrong or am i missing something?

The problem of many developing businesses has always been attributed to insufficient or lack of capital to run these enterprises. But on taking an MBA course at the University, you have come to realize that most businesses in Ghana and Africa fail not because of capital adequacy issues but rather, human resources management issues. What significant expectations would you give to all HR managers as needed competences to be equipped with if you are the consultant general to businesses in Ghana? Discuss these factors or requirements in not more than One and half (11 /2) pages.

Napoleon is contemplating four institutions of higher learning as options for a Master’s in Business Administration. Each university has strong and weak points and the demand for MBA graduates is uncertain. The availability of jobs, student loans, and financial support will have a significant impact on Napoleon’s ultimate decision. Vanderbilt and Seattle University have comparatively high tuition, which would necessitate Napoleon take out student loans resulting in possibly substantial student loan debt. In a tight market, degrees with that cachet might spell the difference between a hefty paycheck and a piddling unemployment check. Northeastern State University and Texas Tech University hold the advantage of comparatively low tuition but a more regional appeal in a tight job market. Napoleon gathers his advisory council of Jim and Pedro to assist with the decision. Together they forecast three possible scenarios for the job market and institutional success and predict annual cash flows associated with an MBA from each institution. All cash flows in the table are in thousands of dollars.

Suppose that the likelihood for each of scenarios 1 through 3 is 0.3, 0.4, and 0.3, respectively. What is the optimal decision under the EVM criterion?

our dream is to take up a job that basically provides wages that has a present value of at least $2,000,000 today (Ignoring taxes). Other words, you want the present value of all net future earning to be greater than 2 million. You want to feel like a millionaire today!
You just completed your master of science in biochemistry and a large bio-medical company wants to hire you. Their offer is as follows: Annual salary of $200,000 starting one year from today. However, they will only offer a contract for twenty years, and they will not guarantee if they can renew your contract. Also, they want you to complete an MBA in your second year and third year while working with them (t=2 and t=3). You must pay for that education (they do not cover education expenses). However, since your first annual paycheck is one year from today (t=1), they are willing to give a contract signing bonus of $100,000 today (if you sign the contract today).
You did some research and realized that you can complete your MBA with Sam Houston State University with a cost of $15,000 per year for two years. You also assume a conservative interest rate of 4% for this calculation. What is the NPV of these cash flows. (Note: 1.5X credit)

2. Calculation of Labor market indicators

Use the following September 2015 data (in millions) for the United States to calculate

(a) the labor force participation rate, (b) unemployment rate, and (c) the employment/population ratio.

September 2015 Data

Civilian Non-Institutional Population (Age 16 and over) 251.3 million

Employed 148.8 million

Not in labor force 94.6 million

Unemployed 7.9 million

Suppose that an innovation earns a monopolist innovator profits of $1 million if there was no infringement. If there was infringement, suppose that the innovator would earn $600,000, while the infringer earns $300,000. a. Under the lost profits protocol, how much compensation is the innovator entitled to? b. Under the unjust enrichments protocol, how much compensation is the innovator entitled to? c. In the United States, how much compensation is the innovator entitled to? d. What if the infringement was willful? Does this change your answer to part c? 10.

Consider the numbers from question 9. Let ? denote the probability that a non-willful infringer in the US is found to be infringing on an innovation. Suppose that by not infringing, the innovator can earn profits of $50,000 using its own technology. Also, suppose that fighting the infringement charge costs the innovator $100,000, regardless of the outcome. For what values of ? is there an incentive to infringe?

You and a friend go to McDonald’s for salads (weird). While you are there, an old man says, “You kids are so lucky today. When I was a kid in the 1950s, I never went to McDonald’s. Look at your fancy phone! Life was hard back then. Not like today. You have it easy. Anyone can be rich today!” Explain (politely) why this old man’s point of view is incorrect:

a. Explain to him whether or not the United States is a meritocracy and the relationship meritocracy has to inequality.

b. Explain what has happened to economic mobility over the last several decades. What has happened to the wealth gap over the last sixty years?

c. Explain how more recent trends in deunionization, wages, income, taxes, and safety net programs have made it even harder for people to earn a decent living, let alone become millionaires.
