Question

a,b,c,d,e,f and g are seated in a straight line facing north but not necessarily in the same order. only three people sit between f and a. neither f nor a sits at the extreme ends of the line. only two people sit between a and g. e is not immediate neighbour of either a or f. e sits third to the left of b. b is not an immediate neighbour of a. e is not an immediate neighbour of c.
1. who are the immediate neighbours of a?
2. who are the immediate neighbours of e?
3.who are the immediate neighbours of f?

Answer 1

b f g e d a c is the order. So, 1. D and C, 2. G and D, 3. B and G

Answer 2

Answer:

Step-by-step explanation:

as only three people sit between f and a. neither f nor a sits at the extreme ends of the line. means both f and a sit at second from end of the row. now

e is not immediate neighbor of either a or f so that e will always sit in the middle. and e sits third to the left of b so b will always sit at right end. as given b is not immediate neighbor of a . it means a will sit at second from left end and f at second from right end.

with all these conditions the final arrangement will be

c a d e g f b

1- immediate neighbors of a are c and d

2- immediate neighbors of e are d and g

3- immediate neighbors of f are g and b
