Question

Four people a,b,c,d are sitting in a row,who is sitting in right

Answer 1

all the four peoples are sitting in right

Answer 2

The possible permutation of letters a,b,c,d are

1. If we place d in right, possible permutation are

a b c d, a c b d,  b c a d, b a c d, c a b d, c b a d

2. If we place c in right, possible permutation are

a b d c , a d b c,  b a d c, b d a c , d a b c, d b a c

3.If we place b in right, possible permutation are

a c d b, a d c b , c a d b, c d a b, d a c b, d c a b

4.If we place a in right, possible permutation are

b c d a, b d  c a , c b d a, c d b a , d c b a, d b c a

So,it totally depends on arrangement which person is sitting right.
