    Dear IL'ites,

    Induslady asked me to conduct this month's contest. Coming after Jenz who so admirably conducted the Nov Book review contest, I have big shoes to fill. It's a puzzle. Here you go!

    In my introductory economics class, the professor said here is how marks and exams work for her course.

    • 50 marks for mid-term exam
    • 50 marks for final exam
    • Total above 90% is an A grade. Below 90% is a B grade.
    However, taking the mid-term is optional (i.e. students can skip it). Students have the option of making the final exam mark count towards the entire 100. Mathematically,

    • If mid-term marks < final-exam marks, then total marks = 2 x final-exam marks
    • If mid-term marks > final-exam marks, then total marks = mid term marks + final exam marks.
    Following are the questions for you..

    1. What is the professor trying to achieve by making mid-term optional?
    2. Why didn't she make the final exam optional?
    3. What type of a student will skip taking the mid-term exam?
    Assume that a student’s motivation is to get an “A” grade. For a student, only grades matter, not the actual marks. Assume teacher’s motivation is to make sure students understand the content of the entire course.

    Any clarifying questions ask in this thread. I will respond here. Please do not private message me for clarifications.

    Please send in your responses to contest@indusladies.com before Dec 24th. Please do not post your response in this thread. Please do not private message your response. Once sending in your responses, just let me know that through this thread. I will acknowledge receipt in this thread.

    All the best!

    Hai.

    By first sight the questions appeared so simple. But,when tried to attempt, it is little complicated.

    Anyhow, i have sent my answers to this.

    Swathi, I have received your entry. I agree, the simplicity of the question belies the complexity of reasoning that is needed to answer it correctly. Thank you.
