Step-by-step explanation:
The traffic lights at three different road - crossing change after every 36 seconds , 60 seconds and 72 seconds . if they change simultaneously at 8 a.m after, what time will they change again simultaneously?
ans - It is given that on Ashok Marg three consecutive traffic lights change after 36, 60 and 72 seconds, respectively. LCM of 36, 60 and 72 is 360. It means after 360 seconds the lights change simultaneously. ... 360 seconds = 8 a.m + 360 seconds = 8 a.m + 6 minute
so at 8 : 06 minutes they will change again simultaneously
