Sir,you've told that if the question asks for a minimum value,we should find the LCM whereas in the questions of type 1,you had mentioned that HCF is the minimum value!Can you please explain the difference once?

Both are different thing. in general HCF is highest common factor but for solving that type of questions you have to consider different point.
sir in question no 2 , if we include 6 am as well as 12 pm, then it will be like , at 6am --1 7am--2 8am--3 9am--4 10am--5 11am--6 12pm--7 , it will ring 7 times ?

not like that. 6-7 = 1 hour 7-8 = 1 hour 8-9 = 1 hour 9-10 = 1 hour 10-11 = 1 hour 11-12 = 1 hour total 6 hour
