Answer:
The answer is 4 rounds
Step-by-step explanation:
The least common multiple of mins is 60 therefore, divide individually to get your answer.
Reena=6 Dipti=4 and Vidhi=5
And also dear, the second time you spelled Reena you spelled out Reema with an m.
Hope this helps :)

Answer:
Dipti would've completed 4 rounds by the time all of them meet again at the starting point.
Step-by-step explanation:
LCM of 10,15,12 =
10 = 2×5×1
15=3×5×1
12=2×2×3×1
LCM = 5×2×3×2×1=60
They all will meet at the starting point again after 60 mins
Dipti takes 15 mins to complete one round. Therefore the number of rounds completed by Dipti in 60 mins is 60/15 = 4
