Study the following information carefully and answer the below questions.

Fifteen students namely B to P five each from three different grade viz. II, III and IV are sitting in three parallel rows each row having six chairs. Students from grade II is north of grade III and students from grade III is north of grade IV. Chairs placed in of grade II sits facing south while chairs placed in grade IV sits facing north. First three chairs placed in grade III (from the west end) facing north while last three chairs placed in grade III facing south.

P sits on the chair third to the left of K, who neither sits adjacent to N nor sits adjacent to O. B sits three places left of O, who neither from grade II nor sits at end of the row. Person in-front of O(opposite)  sits immediate right of M. One person sits between C and M, who sits facing N. C sits to the right of M. M neither sits adjacent to vacant chair nor sits adjacent to P. P is neither an immediate neighbour of O nor N. G sits facing K and sits in-front of the one who sits on the chair which is third to left of E. One person sits between L and E. Person in-front(opposite) of L sits adjacent of J. H sits immediate left of D.I neither sits adjacent to B nor from grade III.F sits to the right of P but not next to K.

A.J sits in-front of B and is second to the right of F.

B.Three person sits between L and I.

C.H sits third to left of N and sits facing M.

D.Two persons sit between F and G.

E. All are not true.

2. What is the position of N with respect to O ?

A.Second to left.

B.Third to right

C.Immediate right

D.Second to right

E.None of these

3.Which of the following combination of person sits facing south in grade III?

A.C & M

B.F & J

C.C &O

D.F & L

E.None of these

4. If B is related to O, similarly J is related to I, then who among the following person is related to D?

A.L

B.F

C.C

D.H

E.None of these

5. What is the position of M with respect to J?

A.Fourth to the left.

B.Third to the right

C.Immediate left

D.Fourth to the right

E. Second to the right

Explanation :

We have:

• B sits three places left of O, who neither from grade II nor sits at end of the row.
• Person in-front of O sits immediate right of M.

• One person sits between C and M, who sits facing N.C sits to the right of M.
• M neither sits adjacent to vacant chair nor sits adjacent to P.

Based on above given information we have:

Again, we have:

• P sits on the chair third to the left of K, who neither sits adjacent to N nor sits adjacent to O. P is neither an immediate neighbour of O nor N. So, case 1(b) gets eliminated.
• G sits facing K and sits in-front of the one who sits on the chair which is third to left of E. So, case 1(a) gets eliminated

• One person sits between L and E. So, case 1(b):I gets eliminated now.
• Person in-front of L sits adjacent of J.

• H sits immediate left of D.
• I neither sits adjacent to B nor from grade III.
• F sits to the right of P but not next to K.

Based on above given information we have final arrangement as follows:

1) Answer: E

2) Answer: C

3) Answer: A

4) Answer: B

Clearly, one person sits between both the pair of person, thus N must be related to D.

Hence, option B is correct choice.

5) Answer: D
