Instructions

Study the following information carefully and answer the questions given below :

Eight persons – L, M, N, 0, P, Q, R and S – sitting around a circular area at equal distance from one another, but not necessarily in the same order. Some of the them are facing the centre while some others are facing outside (i.e., in a direction just opposite to the centre). S is sitting fourth to the left of P. 0 is sitting second to the right of S. S faces outside. L is sitting third to the right of R R is not an immediate neighbour of P. Both the immediate neighbours of Q face towards the centre. Both the immediate neighbours of M face opposite directions (i.e., if one person faces towards the centre, the other person faces outside). Both the imme diate neighbours of S face the same direction as that of 0 (i.e., if 0 faces towards the centre, then both the immediate neighbours of S also face towards the centre and vice-versa). Both the immediate neighbours of P face the just opposite direction of P (i.e., If P faces towards the centre, both the immediate neighbours of P face outside and vice-versa).

Question 153

# How many persons are facing outside ?

Solution

S is sitting fourth to the left of P, => S is sitting opposite to P and S faces outside.

O is sitting second to the right of S.

L is sitting third to the right of R and R is not an immediate neighbour of P,

=> R sits second to the left of S, and faces outside. Thus, L sits to the immediate right of S.

Since, both the immediate neighbours of M face opposite directions and immediate neighbours of Q face towards the centre,

=> N sits between S and R, since they both face outside.

Similarly, Q sits between P and O, where P and O faces the centre and M sits between P and R.

=> P and L faces the centre. The arrangement :

There are 4 persons who are facing outside.

=> Ans - (D)
