Answer:

They will simultaneously ring again at 5:06 a.m.

Step-by-step explanation:

Let a,b,c be the 3 bells

Intervals between the ringing of

bell a = 30 secs

bell b = 40 secs

bell c = 45 secs

they simultaneously ring at = 5 a.m.

At what time will they simultaneously ring again = LCM of 30,40,45 = 360 secs

                                                                                = 360 secs = 6 mins

                                                                                = 5a.m. + 6 min

                                                                                = 5:06 a.m.

We are given that Three bells are ringing continuously at intervals of 30,36 and 45 minutes respectively. So after 180 minutes they ring together . So, after 3 hours they ring together. Therefore they all ring together again if they ring simultaneously at 8 a.m. at 11:00 a.m.
