Certain number of persons are sitting in a linear row facing the north direction. The distance between all the persons is same.
Six persons sit between A and K.
A sits fifth to the right of D.
D sits third from one of the ends of the row.

Three persons sit between K and H, who sits third to the left of M.
C sits immediate right of M.
Thus, Case 1 gets cancelled.

Six persons sit between C and V.

G sits immediate left of D.
As many persons sit to the left of G as to the right of V.

This is the final arrangement.
31 persons are sitting in a linear row.
