8:30 a.m., when will they ring together again?
Three bells ring at intervals of 10, 12 and 15 minutes. If they rang together

please answer me ​

Answer 1

Answer:

Again at 9:30 AM they ring together again.

Step-by-step explanation:

LCM of 10, 12 and 15 is 60. Thus after every 60 minutes they will ring together. Thus next they will ring at 9:30 AM.

Logic : After an hour, first bell rangs for 6th time, second bell rangs for 5th time and third bell rangs for 4th time.
