In this type of questions, some clues regarding seating or placing sequence (linear or circular) of some persons or items is given. The candidate is required to form the proper sequence using these clues and answer the questions accordingly.

Six persons A, B, C, D, E and F are sitting in two rows, three in each.

E is not at the end of any row.

D is second to the left of F.

C, the neighbour of E, is sitting diagonally opposite D.

B is the neighbour of F.

After interchanging seat with E, who will be the neighbours of D in the new position ?

** Option:**

**A.**C and A

**B.**F and B

**C.**Only B

**D.**Only A

**E.**Only C

**Answer: A . C and A**

** Justification:**

The given information can be analysed as follows :

E is not at end. So, E must be in the middle of one of two rows.

D is second to the left of F. So, order of the row must be D -- F.

C is neighbour of E and is sitting diagonally opposite to D means C is under F in the other row

i.e. D __ F

__ E C

B is the neighbour of F.

So, the arrangement must be D B F & A E C

Clearly, neighbours of E are A and C. So, on interchanging the seat with E, the new neighbours of D will be A and C.

So, the answer is (a).
