Answer:
next time the bell rings together = after (LCM of 7,8,11,12) second =1848seconds
number of seconds in 3 hours =3×3600=10800 seconds
number of times they ring together in next 3 hours =10800/1848= 5 (rounded off) (round off it to the number before like the answer was 5.8 something but we need to find Answer within time limit so 5 was the answer)
(PLEASE MARK BRAINLIEST)
