Question 19 & Question 20
Now Mario is at the centre of a circular room, where there are 49 doors around him. Also, he finds a staff, flicking it at a door will toggle 5 consecutive doors, beginning from the door it was flicked at, open doors will be closed while the closed doors will be opened.
Question 19 : Mario’s aim is to apply this flickable staff several times to toggle the state of a single door. What are the possible number of times Mario would have to use this staff to achieve his aim?
(a) 25 (b) 32 (c) 40 (d) 49
Question 20 :
Now suppose, the staff toggles 15 consecutive doors then with how many doors can you acheive his aim of toggling a state of a single door ?
(a) 53 (b) 54 (c) 55 (d) None of these

Re: Question 19 & Question 20
When he will say to toggle first door then first five doors would get open. When he will tell to toggle second door the first door would be open, 2-5 would we closed and 6 would be open when you will go on doing this in 5 times all 10 doors would be toggled now start from 11 door to 20 door and so on. When you would reach 49 th door it would be 25 steps

Firstly 5-5 doors are opened but when 45 doors are opened we again do magic 4 more doors open but first door closed then we again do magic first door opened and next 4 doors closed
In this way in 49 times all doors get opened
In this way in 49 times all doors get opened

The question is asked in a confusing manner which is difficult to understand.
