LCM of 40,30,36,45=360
So they will meet again in 9am + 360/60
=9+6=15=3am

Answer:
3:00 p.m.
Step-by-step explanation:
Given, four girls drink at regular intervals of 40, 30. 36 and 45 minutes.
First, we have to find the L.C.M of these numbers to find out when they will meet for drinking.
L.C.M of 40, 30, 36 and 45
= 360 minutes = 6 hours
If they start drinking at 9:00 a.m. then they all will meet after 6 hours, i.e., 3 p.m.
Hope it Helps!
