Here is what i understood:
1st round jailor opens all the doors,
2nd round jailor closes even no of doors,
3rd round it closes the door which are open and vice versa.
4th round – what will happen? it open<–>close like third round? till the 100th round?
Doubt:
1)I didn’t get how sir wrote that the 12th door will be visited 1,2,3,4,6,12 th times. (MAIN DOUBT)
2)Can you tell me what will happen after 3rd round
hello @anujkumardarji
we are always taking rounds in some multilples. i,e first round in multiples of 1, second round in multples of 2, third round in multiples of 3, fourth round in multiples of 4 so on.
so we can say a particular number will be visted by its factors only.
in case of 12.
its factors are 1,2,3,4,6,12 hence bhaiya wrote this.
same procedure will repeat for 4th round then 5th round then 6th round so…on till 100th round
