Study the following information to answer the given questions.
Eight friends — G, H, I, J, K, L, M and N are seated in a straight line with equal distance between each other, but not necessarily in the same order. Some of them are facing north while some are facing south.
• K is an immediate neighbour of the person sitting at an extreme end of the line. Only three people sit between K and M.
• J sits second to the right of M. J does not sit at an extreme end of the line.
• N sits to the immediate left of G. N is not an immediate neighbour of M. Immediate neighbours of G face opposite directions (i.e. if one neighbour faces north then the other faces south and viceversa.)
• Person sitting at the extreme ends face opposite directions (i.e. if one person faces north then the other faces south and viceversa.)
• H sits second to the left of L. L faces north. L is not an immediate neighbour of K.
• Immediate neighbours of L face the same direction (i.e. if one neighbour faces north then the other also faces north and viceversa.)
• Both K and H face a direction opposite to that of J (i.e. if J faces north then K and H faces south and viceversa.)

Question 87

How many persons sit to the left of G?.

Solution

K is an immediate neighbor of the person sitting at an extreme end of the line. Only three people sit between K and M.
There can be two possible scenario
_ [K] _ _ _ [M] _ _ & _ _ [M] _ _ _ [K] _
N sits to the immediate left of G. N is not an immediate neighbour of M. "↑" is north and "↓" is south.

H sits second to the left of L. L faces north.

L is not an immediate neighbour of K.
_ [K] [H]_ [L] [M] _ _ , _ [K] _ _ [H] [M] [L] _ & _ [H] [M] [L] _ _ [K] _
As G and N need to be together
_ [K] [H]_ [L] [M] _ _ , _ [K] [G/N] [H] [M] [L] _ & _ [H] [M] [L] [G/N] [K] _
J does not sit at an extreme end of the
[I] [K] [H] [J] [L] [M] [G] [N] ,(N is not an immediate neighbour of M)
thus only possible Solution remains
Immediate neighbours of L face the same direction, immediate neighbours of G face opposite directions and Person sitting at the ends face opposite direction
