ICAI solution is similar to the solution in padhuka. Padhuka has mentioned the S.No of persons waiting.

For length of waiting line.I would suggest you to start looking at the solution from the end.See the arrival time of the last person, that is 11:57 check if any service end time for any persons before him is after 11:57, if not then there is no waiting line.

For the 17th person - arrival time 11:43 ,now search for service end time for persons before him after 11:43 ,you'll see that for 15th & 16th customer the service end time is 11:44 & 11:46, that is to say that he arrived before the above two persons left.So the length of waiting time is 2. :)
