The correct answer is
O

To solve the problem of determining which person has an exam on Friday, we need to deduce the order of exams based on the given conditions. The days of the week from Monday to Sunday are assigned as M, T, W, Th, F, Sa, Su respectively.

  1. It is given that only two people have exams before R. Therefore, R must have his exam on Wednesday.
  2. There is only one person who has an exam after M. Thus, M's exam must be on Saturday (since it is the only day left for him to have only one person after him).
  3. There are three people between R and T. If R is on Wednesday, then T must be on Sunday, because that's the only position with three people in between (Thursday, Friday, Saturday).
  4. There is only one person between S and G. Additionally, J's exam is immediately before S. This forms a pair J and S.

To fit all these rules, let's plug these into the available days:

  • Monday: J (because their exam is one day before S, and Tuesday is the only available spot for S.)
  • Tuesday: S
  • Wednesday: R
  • Thursday: G (since there must be one day between S and G)
  • Friday: O (only logical spot left for O)
  • Saturday: M
  • Sunday: T

Thus, O has their exam on Friday, confirming that O is the correct answer according to the given conditions.
