Question 83

Two persons are climbing up on two moving escalators which have 120 steps. The ratio of 1st person’s speed to that of 1st escalator is 2:3 (steps). The ratio of 2nd person’s speed to that of $$2^{nd}$$ escalator is 3:5 (steps). Find the total number of steps they both have taken

together.

Question 84

The table below shows the temperatures in degrees Fahrenheit in a city over one week. If m represents the median temperature, f represents the temperature that occurs most often, and a represents the average (arithmetic mean) of the seven temperatures, which of

the following is the correct order of m, f, and a?

Question 85

Inside a triangular park, there is a flower bed forming a similar triangle. Around the flower

bed runs a uniform path of such a width that the sides of the park are exactly double the

corresponding sides of the flower bed. The ratio of areas of the path to the flower bed is:

Question 86

Consider the following piecewise definition of the function f.

$$f(x) = \begin{cases}3 - x, if & x \leq 0\\x^2 + 2, if & x \geq 0\end{cases}$$

Evaluate f(-3).
