Given that Three bells ring at interval of 36 seconds, 40 seconds and 48 seconds respectively. To find particular time after which they will ring together, we need to find L.C.M of 36,40 & 48. L.C.M of 36,40 & 48 is 720. Therefore three bells will ring together after every 720seconds i.e.., 12minutes.
