Study the following information carefully and answer the below questions:

There are eight persons; they sit in each line such that the person sitting in line 1 sits at the same position in line 2. Their names are consecutive alphabets but not necessarily in the same order. All of them are facing north direction.

In line 1: Distance between second and first person is a multiple of 11m and increasing consecutively from left to right.

In line 2: Distance between second and first person is a multiple of 13m and increasing consecutively from left to right.

The distance between K and M is not even numbered value in line 1 but both the persons are immediate neighbours. N is not an immediate neighbour of K. Persons name with Consecutive alphabets does not sit together. All the person position in line 1 is same as in line 2. In line 1, the sum of the distance between N and I and the distance between O and J is same as between K and M. N sits third to the right of O. The length of line 1 is smaller than line 2. The distance between P and I in line 1 is same as the sum of the distance between J and O and the distance between N and I in line 2. Two persons sit between N and M.

C.13 m

D.15 m

E.10 m

5) Who among the following person sits to the immediate right of N?

A.P

B.M

C.K

D.I

E.L

Explanation

We know that,

The length of Line 1 is 462

Distance between 2^nd and 1^st person is multiple of 11 and consecutive number from left to right.

The total person is 8-1=7, which is the number of different distance in a line.

The centre of the two person distance is 462/7=66

Or another way,

X+X+11+X+22+X+33+X+44+X+55+X+66=462

7X+231=462

X=33

(i) The distance between K and M is not even numbered value in line 1 but both the persons are sitting immediate neighbours.

(ii) N is not an immediate neighbour K. Consecutive alphabet persons not sit together.

(iii) All the person position in line 1 is same as in line 2.

(iv) In line 1, the sum of the distance between N and I and the distance between O and J is same as between K and M.

(v) N sits third to the right of O.

JO+NI=KM

So, KM distance value is 99m, there is no another way.

(vi) The length of the line 1 is smaller than line 2.

(vii) The distance between P and I in line 1 is same as the sum of the distance between J and O and the distance between N and I in line 2.

(viii) Two persons sit between N and M.

Case (ii) and (iv): does not follow the condition (viii).

Case (iii): does not follow condition (vii) and (vi), because the length of line 1 is smaller than line 2.

1. And PI (line 1)=JO+NI (line 2).
2. The numbers of persons sit between J and N is 3.
3. So, we get, OJ=X, LO=X+13, IL=X+26, NI=X+39.
4. Distance between OJ=X; and NI=X+39
5. So, we get, 143=X+X+39

X=52.

The distance of P and I is 143,

X+X+13+X+26+X+39+X+52+X+65+X+78

52+65+78+91+104+117+130=637m
