Answer:
e) 8:40 AM
Step-by-step explanation:
Time period between any two successive rings of all the three bells:
A: 60/6 = 10 minutes
B: 2* 60/15 = 8 minutes
C: 4* 60/6 = 40 minutes
LCM OF (10,8,40) is 40
Hence all the three bells will ring together in an interval of 40minutes.
The earliest time by which three bells ring together again will be 40 minutes after 8:00 AM that is, 8:40 AM on the same day
