Five documentary films covering five different topics (history, art, environment, politics, and science) are being shown during a two-day film festival. There are two time slots each day, morning and night, and up to three movies can be shown in each time slot. Although no film is to be played more that once during the same time slot, every film must be shown at least twice. In addition, the following rules hold:

  • Politics and science are never shown in any time slot together.
  • If history is shown in a slot on the first day, art is also shown.
  • History is only shown in the morning.
  • The environment film is shown twice on the second day.
  • Only two films are shown on the second night.

Based on the information given, identify a film that could not be shown on the morning of the first day and a film that could be shown three times during the festival.

Given :

--> Politics and Science movie cannot be together on any slot. We have 4 slots for 2 days.If Politics movie is in the morning slot then Sciene movie will be in the evening slot and viceversa.
Therefore , Politics and Sciene will not be the answer. So elimate Politics and Science.

--> As stated, History is shown in the morning only, and If history is in the morning slot of the first day then art movie will also be shown in the morning slot.
Therefore, history will not be shown three times. So eliminate History form the answer choices

-> So it bring the answer choices to either Arts/ Env movie.
Art movie will be shown on the first day morning slot because of the condition 2 and 3. Therefore Env has to be the answer to the first question( which movie is not shown in the first morning)

--> Env movie, it is shown 2 times in the second day, While Arts cannot be shown in the 2nd day. The reason is shown below.

So to sum up :

First Morning slot : History, Arts , (either Politcs /Science )
First Evening Slot : Either Science/Politics, ( 2 movie slots remaining , and one has to be Arts because the 2nd day slots are all packed and Arts has to be shown twice)

Second DaY Morning Slot : History, Env and (either Politcs /Science )
Second DaY Evening Slot : Env and (either Politcs /Science ) , third slot is not there as per the condition that only 2 shows are there for the 2nd day evening slot.


Therefore ,

Env movie is not shown in the morning slot

Env movie could be shown three times.


Hope this helps.

Cheers !!!!!!

for IR...you shuld solve in 3.20 seconds if skippping 3 questions ...

How to solve this in under 3.30 seconds ?

It took me 3.30 mins to write and understand what was going on ?

Realistically this will take most people 5 - 6 mins, would it not ?
