Rahul takes twice as such time as Manick and thrice as much time a Sachin a job. If working together, they can complete the job in 4 days, find the time taken by each of them separately to complete the work.

Explanation

To solve the problem, we need to find the time taken by Rahul, Manik, and Sachin to complete a job individually, given that they can complete the job together in 4 days.

### Step-by-Step Solution:

1. **Define Variables:**
- Let the time taken by Manik to complete the job be \( M \) days.
- Since Rahul takes twice as much time as Manik, the time taken by Rahul will be \( R = 2M \) days.
- Since Rahul takes thrice as much time as Sachin, we can express Sachin's time as \( S = \frac{R}{3} = \frac{2M}{3} \) days.
