Answers
Given : A group of five boys a, b, c, d and e and a group of five girls p, q, r, s and t are standing in a row facing each other
To find : Their positions
Solution:
group of girls is facing north
=> boys are facing South
C is to the immediate right of b and d is to the immediate left of a,
=> c & b together and d & a together ;
=> e will be at Center / Middle
A is second to the left of b, and right of d
=> A will be 4th Hence boys position would be
c b e a d
p is facing a
s & r not facing b & d
=> s & r will face c & e
=> q will face b or d
if q face d then no one between p & q
=> no one between r & s ( which is not possible as then one of r or s has to face b)
=> q face b
=> there is one person between p & q
=> r & s will face c & e ( their exact position not defined)
Hence t will face d
c b e a d
r q s p t
or
c b e a d
s q r p t
