The answer is 34.
Here’s the explanation: When you enter the bedroom, there are initially 34 people present. Regardless of the action you take, the total number of people physically present in that room doesn’t change. Even after killing 30, the other 4 remaining people are still there, along with your own presence, making the total still 34. The question plays with assumptions and misdirection, but the figures remain constant based on the initial setup.
