To find Mohan's play day, we need to place the six activities, Physics, Chemistry, Mathematics, Biology, Social Science and Play, across Monday to Saturday using the given clues, then check each option:

  1. Monday: Clue (vi) ties Physics to the day right before Play, and clue (viii) ties Social Science to the day right after Play, so Physics-Play-Social Science must run as three consecutive days. If Play were on Monday, Physics would need a day before Monday, which does not exist, so Monday is not possible.
  2. Tuesday: Placing Physics-Play-Social Science on Monday-Tuesday-Wednesday works: this leaves Chemistry and Biology, which must be consecutive (clue v), to fit with a two-day gap from Social Science (clue vii), landing Chemistry on Friday and Biology on Saturday, and Mathematics on the one remaining day, Thursday, which also satisfies clue (iv). Every clue is satisfied, so Play falls on Tuesday.
  3. Wednesday: If Play were on Wednesday, Physics would be Tuesday and Social Science Thursday. Fitting the Chemistry-Biology pair with the required two-day gap while also keeping Mathematics off the first and last day cannot be made to work with the days that remain.
  4. Thursday: If Play were on Thursday, Physics would be Wednesday and Social Science Friday, leaving only Monday, Tuesday and Saturday for Chemistry, Biology and Mathematics. Chemistry and Biology, kept consecutive, would take Monday-Tuesday, forcing Mathematics onto Saturday, the last day, which directly violates clue (iv). This option fails.

Only placing Play on Tuesday allows every clue, the Physics-Play-Social Science block, the Chemistry-Biology block, the two-day gap and Mathematics's placement, to hold together consistently.

Therefore, the correct answer is Tuesday.

Instead of testing each day one at a time, we can build Mohan's entire week directly from the clues and then simply read off the play day. Let's check each option once the full schedule is known:

  1. Monday: Building the schedule, Physics-Play-Social Science must run as three straight days (clues vi, viii), and placing this block from the start of the week gives Physics=Monday, so Play cannot itself be Monday, that slot belongs to Physics.
  2. Tuesday: With Physics on Monday, the day right after it is Tuesday, and clue (vi) puts the play day immediately after Physics day. Completing the rest of the schedule, Social Science=Wednesday, Mathematics=Thursday, Chemistry=Friday, Biology=Saturday, keeps every clue satisfied, so Tuesday is confirmed as the play day.
  3. Wednesday: In the completed schedule, Wednesday is already taken by Social Science, the day right after the play day, so Wednesday cannot itself be the play day.
  4. Thursday: In the completed schedule, Thursday is already assigned to Mathematics, leaving no room for Thursday to also be the play day.

Building out the full week from the clues fixes Physics on Monday and the play day right after it, on Tuesday, with every other subject falling neatly into place around that.

Therefore, the correct answer is Tuesday.

Using the schedule derived from the clues, Physics falls on Monday and Biology falls on Saturday. We need the number of days that lie between these two, and can check each option:

  1. One: A gap of one day would place Physics and Biology only a single day apart, such as Monday and Wednesday. That is far too close given Physics is on Monday and Biology is on Saturday.
  2. Two: A gap of two days would place Biology on Thursday if Physics is Monday. Biology, however, is fixed on Saturday, not Thursday, so this does not match.
  3. Three: A gap of three days would place Biology on Friday if Physics is Monday. Biology is on Saturday, one day later than this, so this option is also incorrect.
  4. Four: Counting the days strictly between Monday and Saturday gives Tuesday, Wednesday, Thursday and Friday, four days. This exactly matches the gap between Physics (Monday) and Biology (Saturday).

Since Physics is on Monday and Biology is on Saturday, the four days of Tuesday, Wednesday, Thursday and Friday lie between them.

Therefore, the correct answer is Four.

Assign each reading day a number, Monday=1, Tuesday=2, Wednesday=3, Thursday=4, Friday=5, Saturday=6, since Sunday is a holiday and not part of the reading week. Physics sits at position 1 and Biology sits at position 6. Let's check each option using this numbering:

  1. One: A gap of one would mean Biology sits at position 1+1+1=3, Wednesday, not position 6. This does not match.
  2. Two: A gap of two would place Biology at position 1+2+1=4, Thursday, still short of position 6.
  3. Three: A gap of three would place Biology at position 1+3+1=5, Friday, one short of Biology's actual position 6.
  4. Four: A gap of four gives position 1+4+1=6, exactly Biology's position, Saturday. This matches precisely.

Counting from position 1 to position 6 covers 5 steps in total, but the number of days strictly lying between them, excluding both endpoints, is one less than that, four days.

Therefore, the correct answer is Four.

Social Science's position is fixed by its relationship to the play day (clue viii) and its distance from Biology day (clue vii). Let's check each option against the full schedule derived from all the clues:

  1. Monday: Social Science must come immediately after the play day (clue viii), and the play day itself must come immediately after Physics day (clue vi). If Social Science were Monday, play day and Physics day would both need to fall before Monday, which is impossible since Monday is the first reading day.
  2. Tuesday: This would require play day on Monday and Physics day before Monday, again impossible for the same reason as above.
  3. Wednesday: This fits the Physics-Play-Social Science block on Monday-Tuesday-Wednesday. With this placement, the two-day gap rule (clue vii) forces Biology onto Saturday and, since Biology follows Chemistry directly (clue v), Chemistry falls on Friday, leaving Thursday for Mathematics, which also satisfies clue (iv). Every clue lines up correctly.
  4. Thursday: Placing Social Science on Thursday would push Physics to Tuesday and play day to Wednesday, but then satisfying the two-day gap to Biology while also keeping Mathematics off the first and last days cannot be done with the days that remain.

Only the Wednesday placement keeps every clue, the Physics-Play-Social Science sequence, the Chemistry-Biology sequence, the two-day Biology gap and the Mathematics restriction, consistent at once.

Therefore, the correct answer is Wednesday.

Clue (viii) directly ties Social Science day to the day right after the play day, so once we know the play day, Social Science follows immediately. Let's confirm this against each option:

  1. Monday: For Social Science to be Monday, the play day would need to be the day before Monday, which doesn't exist within the reading week, so Monday is impossible.
  2. Tuesday: This would require the play day to be Monday, but Physics day must fall immediately before the play day (clue vi), and Physics also cannot be placed before Monday, so this fails too.
  3. Wednesday: With Physics on Monday and the play day immediately after it on Tuesday (clue vi), Social Science, immediately after the play day (clue viii), lands on Wednesday. Completing the remaining days with Mathematics on Thursday, Chemistry on Friday and Biology on Saturday satisfies every other clue as well.
  4. Thursday: This would push the play day to Wednesday and Physics to Tuesday, but then fitting Chemistry, Biology and their required two-day gap from Social Science into the remaining days cannot be done consistently.

Since Physics day and the play day are fixed on Monday and Tuesday respectively, applying clue (viii) directly places Social Science on Wednesday, the day right after the play day.

Therefore, the correct answer is Wednesday.

Mathematics day is constrained by clue (iv): it cannot be the first or last reading day, and it must fall before Chemistry day. Let's test each option:

  1. Monday: Clue (iv) explicitly rules out Mathematics being the first day, so Monday is not possible.
  2. Tuesday: With the Physics-Play-Social Science block occupying Monday to Wednesday in the valid schedule, Tuesday is already taken by the play day, so Mathematics cannot sit here.
  3. Wednesday: Wednesday is already occupied by Social Science in the valid schedule, the day right after the play day (clue viii), so Mathematics cannot be placed here either.
  4. Thursday: With Physics on Monday, Play on Tuesday and Social Science on Wednesday, and with Chemistry and Biology needing Friday and Saturday to satisfy the two-day gap from Social Science (clue vii), Thursday is the only day left for Mathematics. It is neither the first nor the last day, and it falls before Friday's Chemistry, satisfying clue (iv) fully.

Every other day is already claimed by another subject or activity once the full schedule is worked out, leaving only Thursday free for Mathematics.

Therefore, the correct answer is Thursday.

Since Mohan's week has exactly six reading-related activities, Physics, Play, Social Science, Chemistry, Biology and Mathematics, spread over six days, Mathematics day must be whichever single day is left once the other five are placed. Let's check each option:

  1. Monday: Monday is already fixed as Physics day, since Physics day comes immediately before the play day (clue vi) and the block Physics-Play-Social Science must start at the beginning of the week to fit every other clue. Monday is unavailable for Mathematics.
  2. Tuesday: Tuesday is already claimed by the play day, immediately after Physics day, so it cannot also be Mathematics day.
  3. Wednesday: Wednesday is already claimed by Social Science day, immediately after the play day (clue viii), so it is unavailable too.
  4. Thursday: With Monday, Tuesday and Wednesday taken by Physics, Play and Social Science, and Friday, Saturday needed for Chemistry and Biology to satisfy the two-day gap from Social Science (clue vii), Thursday is the only day left over. It also satisfies clue (iv) directly, being neither the first nor last day, and falling before Friday's Chemistry.

With five of the six days already committed to the other five activities, Thursday is the single remaining day, and it happens to satisfy every restriction placed on Mathematics day as well.

Therefore, the correct answer is Thursday.

Using the full weekly schedule, Monday: Physics, Tuesday: Play, Wednesday: Social Science, Thursday: Mathematics, Friday: Chemistry, Saturday: Biology, we can check each statement:

  1. Biology day is after Chemistry day: Chemistry falls on Friday and Biology falls on Saturday, one day later. This statement holds true, matching clue (v) directly, which places Biology immediately after Chemistry.
  2. Physics day is on Wednesday: Physics actually falls on Monday, not Wednesday, so this statement is false.
  3. Play day is on Monday: The play day falls on Tuesday, not Monday, since Physics must come immediately before it (clue vi) and Physics itself is on Monday. This statement is false.
  4. Chemistry day is earlier than Physics day: Chemistry is on Friday and Physics is on Monday, so Chemistry actually falls much later than Physics, not earlier. This statement is false.

Only the first statement, that Biology day comes after Chemistry day, holds up against the schedule.

Therefore, the correct answer is Biology day is after Chemistry day.

Instead of relying on the full calendar, we can check each statement directly against the clue it corresponds to:

  1. Biology day is after Chemistry day: Clue (v) states plainly that Biology day is on the immediate next day of Chemistry day, which is exactly what this statement claims. This matches the clue word for word.
  2. Physics day is on Wednesday: Working out the schedule places Physics day on Monday, since the Physics-Play-Social Science block (clues vi, viii) must sit at the start of the week for every other clue to fit, so Wednesday is incorrect.
  3. Play day is on Monday: Clue (vi) requires Physics day immediately before the play day. With Physics fixed on Monday, the play day must be Tuesday, not Monday, so this statement is false.
  4. Chemistry day is earlier than Physics day: Chemistry, paired immediately before Biology on Saturday (clue v), falls on Friday, well after Physics day on Monday, so this statement has the order reversed and is false.

Only the first statement lines up directly with a clue, clue (v) itself confirms Biology day comes immediately after Chemistry day.

Therefore, the correct answer is Biology day is after Chemistry day.
