Question
Six persons (N, O, P, Q, R and S) sit in a linear row and
face in north direction. Q sits third to the right of P. Only R sits to the right of S. O sits to the right of N. How many persons sit to the right of O?Solution
Q sits third to the right of P.
P ___ ____ Q
Only R sits to the right of S.
P ___ ____ Q S R
O sits to the right of N.
P N O Q S R
Final arrangement:
P N O Q S R
