Please am preparing for my exam. Try to simplify as much as possible. This is a previous year exam sat by the same Professor. But I don't really get answers after solving the problem. Would you please try to solve it and circle the correct answers from the questions given below the figure. What is the trick/underlying idea that I should use to tackle a similar problem?
