Dupe's present age = 14 years
Olu's present age = 11 years
Explanation:
- Let Dupe's age be x. Let Olu's age be y. Since their ages add up to 25 years, x + y = 25
- Eight years ago Dupe's age was double that of Olu's age. Solving by simultaneous equations. Four methods are Elimination Method, Graphical Method, Substitution Method, and Matrix Method. Let us try out Elimination method for solving a pair of simultaneous linear equations that reduces one equation to one that has only a single variable. Once this has been done, the solution is the same as that for when one line was vertical or parallel.
- Therefore, eight years ago, Dupe's age was 6 and Olu's age was 3 so that x=2y becomes, 6=2*3. Eight years hence, x=6+8=14 and y=3+8=11. That makes, x or Dupe's age as 14 years and y or Olu's age as 11 years.
Answer:
8.01%
Explanation:
Expected return on mutual fund = Risk-free rate + Market risk premium*Beta
Expected return on mutual fund = 3% + 7.7%*1
Expected return on mutual fund = 10.70%
Best estimate of the portfolio expected rate of return = Weight of mutual fund*Expected return on mutual fund + Weight of risk-free Treasury bills*Expected return on risk-free Treasury bills
Best estimate of the portfolio expected rate of return = 65%*10.70 + 35%*3
Best estimate of the portfolio expected rate of return = 0.08005
Best estimate of the portfolio expected rate of return = 8.01%
Answer:
Foreign exchange
Explanation:
The process of converting the currency of one country to another is known as foreign exchange or Forex. Converting or exchanging to a particular currency is buying that currency. One needs to have their home currency or any other currency to convert it to the desired currency.
If both currencies have equal strengths, then one unit of a currency should exchange with one unit of the other. The exchange rate would be one. Since currencies have different strengths, they convert or exchange at different rates.
