see its simple it's given that first it descents 4 steps and then 2 steps and then one step so when we will add 4 + 2 + 1 we will get 7 and you have said that if the lift repeated twice that means 7 + 7 which is 14

Answer:
14 floors
Step-by-step explanation:
A lift descends = 4 floors
Next = 2 floors
Finally = 1 floor
So ,
4 + 2 + 1
= 7
It repeats this motion 2 times meaning multiply by 2
So ,
7 × 2 = 14
Therefore, The total number of floor it descends is 14 per day
