Answers
Answer:
The answer will 7 days both of them will be delivering the coaching sessions on same day.
Step-by-step explanation:
Let us find it...
Meenakshi goes to every 3 days in total of 147 days.
So her total coaching days will be 147/3 = 49 days.
Shweta goes to every 7 days in total of 147 days.
So her total coaching days will be 147/7 = 21 days
Difference of total days between two are 49 – 21 = 28
Difference of days in their coaching days are = 7 – 3 = 4
So the total days when they delivered the coaching together are
= 28/4 = 7 days
Both of them delivered the coaching together in 147 days are 7 days.
