Question

You enter a room of 38 people,a shooter enter then kill 30,how many people are left in the room?

Answer 1

Answer:

there are now 9 people left in the room by including the shooter as well.

Answer 2

The number of people left in the room is 10.

Step-by-step explanation:

The number of people in the room is given as:

N = (Number of people in room) + (Number of people entered the room) + (Number of people left the room) - (Number of people killed)

Number of people in the room = 38 (Given)

Number of people entered the room = Person entered (me) + Shooter = 2

Number of people left the room = 0

Number of people killed = 30

Now, the number of people left in the room is given as:

N = 38 + 2 + 0 - 30

N = 40 - 30

∴ N = 10
