Deductive reasoning practice test HELP!!

Hi everyone,

I am currently attempting the SHL deductive reasoning test and these two questions have got me confused and I’m sure I’m missing something.

In the first screenshot, my instinct is that the overall setup, training and take down would be 2 hours and 15 minutes but this question only allows for 2 one hour time slots to be added to room 4’s schedule. I then thought that 11-12 and 2:30 till 3:30 allowing for time to set up and take down when room 3 is free. I’m not sure if this is right or if I’m making this more complicated than it needs to be.

Furthermore, the second screenshot is even more baffling as my first thought was to schedule team d to work with team a between 11 and 12 giving 8 people to man the fort. However, there is a slot between 2 and 3 where no one is working, meaning that if team d is scheduled for that time, there’s would be less staff than required. The questions doesn’t seem to allow you to move around staff members which is even more frustrating.

Thank you for reading my rambles. Please help !!
