James was trying to sleep one night but there was too much noise around him. His clock ticked every 20
seconds; a tap was dripping every 15 seconds and his
pet dog snored every 27 seconds. He noticed on his
clock that all three events happened together on the
stroke of midnight.
(a) After how many minutes would all the three
events happen together again?
(b) How many times would all three events happen together again between midnight and one o’clock?
