sonia takes to complete a round = 18 minutes
ravi takes to compelete a round = 12minutes
a.t.q
sonia = 18= 2*3*3
ravi = 12= 2*2*3
Lcm = 2*2*3*3
=36 minutes

Answer:
HOPE THIS HELPS...........
PLEASE MARK AS BRAINLIEST .....
Step-by-step explanation:
Time (sonia)=18 min
time(ravi)=12min
time(other)=15 min
In such problems we take the LCM of the given values
Since we have to find the least time after which they meet.......
∴ LCM of 18, 12, 15 is (180) . [ by finding using any suitable method ]
Therefore they meet after 180 minutes of the start.
