The Remaining People Went Out on The Ground Floor. After That, How Many People Went Out on The Ground Floor? Also, Complete the Following Blanks.

b. If people were going out from the lift, make a subtraction and if
people entered the lift, make an addition.
By the given information, the correct answer is:
After 2 people leave the lift on the ground floor, the lift will be empty.
If the lift is going upward, make the addition. If the lift is going downward, make the subtraction.
a. A boy is on the 5th floor; he goes 3 floors upward. He reaches at: 5 + 3 = 8th floor
b. A girl is on the 8th floor. She goes 5 floors downward.
She reaches 8 – 5 = 3rd floor.
c. A girl is on the ground floor; she goes 11 floors upward.
She reaches 0 + 11 = 11th floor
(A ground floor is considered as the 0th floor.)
d. A girl is on the 3rd floor; she goes 3 floors downward.
She reaches 3 – 3 = 0th floor.
The ground floor is considered the 0th floor.
