There are three persons sit between N and C. L sits `2^(nd)` to the left of C. There are six persons sit between C and B, who sits `3^(rd)` from one of the end. B sits `2^(nd)` to the left of R, who does not sit at the extreme end. There are four persons sit between O and N. More than three persons sit between M and O. There are two persons sit between K and R.
How many persons are sitting in the row?

Options

A. 12
B. 15
C. 18
D. 16

Answer

D

Explanation

From the given statements, there is one person sits between N and M and one of them are sit at the extreme end of the row. There are three persons sit between N and C. L sits `2^(nd)` to the left of C. Here we get 3 possibilities i.e. Case 1, Case 2 and Case 3.

From the given statements, there are six persons sit between C and B, who sits `3^(rd)` from one of the end. B sits `2^(nd)` to the left of R, who does not sit at the extreme end. From this condition Case 1 is ruled out now.

From the given statements, there are four persons sit between O and N. More than three persons sit between M and O. From this condition Case 2 is ruled out now. There are two persons sit between K and R.
