Answer:
It will again beep at 12:20p.m.
Step-by-step explanation:
L.C.M. of 50 and 48 = 1200
sec - min
1 sec = 1/60min
1200sec = 1200 × 1/60 = 20min
12 hours + 20 mins = 12:20p.m.

Step-by-step explanation:
here, you need to find the LCM of 50 and 48 seconds
LCM (50,48) = 1200 seconds = 1200/60 min = 20 min
Therefore, they will beep together at 20 min after 12 noon, i.e. at 12:20 pm
