Answer 1

Given,

An elevator is on the twentieth floor. It goes down $11$ floors and then up $5$ floors

We have to find the present position of the elevator

Solution,

Position of elevator $=20$th floor

First we have to subtract $11$ from $20$ we get remaining floors

After that add $5$ to remaining floors

Present position of elevator $= 20$ th floor $-$ $11$th floor $+5$th floor

$= 20-11+5$

$= 9+5$

$=14$

Therefore, the elevator on now floor is $14$.
