Question
Five bells commence tolling together and toll at
intervals of 2, 4, 9, 12 and 15 seconds respectively. In 45 minutes, how many times do they toll together?Solution
LCM of the time intervals will be 2,4,9,12, and 15 will be 180. 1 min = 60 seconds. 180 seconds = 180/60 = 3 minutes. Therefore number of times they all toll together = (45/3)Â + 1 = 16 times.
