Answer:
obviously all the three Bells toll together after an interval which is the multiple of 4 minutes, 6 minutes, 8 minutes.
LCM of 4,6,8min=24min
therefore,the time when they will next toll together =24min
hence,the number of times they will strike together in (9:45am-8:00am)105 min=(105*60)/24
