How to solve Scheduling Reasoning problems?

Scheduling problems are always an integral part of all reasoning tests. Here I am going to share a few questions and the solutions which will help you understand a few underlying concepts.

Let’s jump straight to example.

Ques. The annual week of Govt School Hisar is approaching. There will be 6 plays that are selected by management which are scheduled from Monday to Sunday. There will be 1 day’s break during the annual week. Order of 6 plays P1, P2, P3, P4, P5, and P6 is not decided. Each of the 6 plays has a different duration i.e. 30 min, 60 min, 90 min, 120 min, 150 min, 180 min, again not in the same order.

It’s decided that the break will not be on Sunday and play of 30 min duration is scheduled on Sunday. Play P1 is scheduled immediately before play P5. There are 2 plays scheduled within play P6 and Play P3. Play P6 has a duration of 180 minutes and P3 has a duration of 90 minutes.

The break day is after the staging of Play P4. There are 2 days between the off-day and play P1. Play P4 is of the duration of 120 minutes, P4 is not staged on Monday. The play immediately before the off day is of 180 minutes. Play P1 is not greater than 150 minutes.

Answer the following questions based on the above information.

1. How many Plays are scheduled before the off day?

2. Which day is the off day?

3. When is play P4 scheduled?

4. What is the duration of play P2?

5. Which Play lasts for exactly 60 min?

Correct Answers are at the end of the article.

We know that many plays are scheduled after P1, so P1 can’t be on Sunday, so P1 is not 30 min, it is 60 min.

Also, P5 is not on Sunday, as there are plays scheduled after P5.

P4, P5, P6 are not on Sunday because they are not 30 min duration, so P2 is on Sunday. The table now Becomes.

Step 4 Solution for Scheduling Questions

We know that there are 2 plays scheduled between P6 (180 min) and P3 (90 min).

If P3 is playing after P6 then P3 has to play on Sunday but P2 is on Sunday.

Hence we know that P3 is 2 days before P6.

Keeping these in mind only has this sequence possible.
