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.

I believe the correct answer would be option A. The government regulate natural monopolies by ensuring and overseeing one supplier. A natural monopoly would happen when a largest manufacturer of a certain industry would have a very big gap as compared to other competitors. These industries are being regulated so as to minimize monopolization and to maintain the competitive equality between industries. Monopolies are mainly being governed by antitrust laws on a national level and on an international level. The ways that the government is regulating are establishing average cost pricing, price ceiling, Rate of return regulations and taxation laws.
