Seven workers namely A, B, C, D, E, F and G are sitting around a circular mat on the ground to work on making a rope. They all face inside the center of the circle. 
Two workers sit between B and F. G sits immediately right of B. So, there are two cases possible i.e., Case 1 and Case 2. 

Three workers sit between A and E. D sits immediately right of A. C sits third to the left of D. So, Case 1 will be invalid. 

Finally, we get, 

As C sits second to the right of G in the same way B sits second to the right of A.
