Directions (67-69) : Study the following information carefully and answer the questions given  below:
Six persons sit around a circular table but not necessarily in the same order. Three of them face inside while rest three face outside the centre. All of them get different marks in an examination viz. 16, 18, 20, 25, 27 and 36 but not in the same order as given.

T sits second to the right of O and gets the marks which is a cube of a number. One person sits between T and X who faces the same direction as O. The one who gets double the marks of O is an immediate neighbour of T. L sits second to the right of R who gets 7 marks less than T. L does not get the highest marks. R and O face opposite directions. Immediate neighbours of R facing the same direction. K is not an immediate neighbour of X. The one who gets 16 marks sits second to the right of T but immediate left of the one who gets 25 marks. R doesn’t face inside

Who among the following sits second to the left of the one who gets fourth lowest marks?

Correct Answer: R

Step-by-Step Explanation:

1. Analyze the given information:

• Total persons: 6 (T, O, X, L, R, K)

• Facing direction: 3 face inside, 3 face outside.

• Marks available: 16, 18, 20, 25, 27, 36.

2. Determine individual marks:

• T gets marks equal to a cube of a number. The only cube among the options (16, 18, 20, 25, 27, 36) is 27 (since 3³ = 27). So, T = 27.

• R gets 7 marks less than T. So, Marks of R = 27 - 7 = 20. Thus, R = 20.

• The one who gets double the marks of O is an immediate neighbour of T. Since available marks are 16, 18, 20, 25, 27, 36, O's marks must be 18 because 18 × 2 = 36 (which is in the list). Thus, O = 18, and the neighbor of T gets 36 marks.

• L does not get the highest marks (36). Therefore, the one with 36 marks must be either X or K.

• Remaining marks for L, X, K are 16, 25, and 36.

3. Determine seating arrangement and facing directions:

• R doesn't face inside, which means R faces outside.

• R and O face opposite directions. Since R faces outside, O faces inside.

• T sits second to the right of O. Since O faces inside, place O, and counting two positions to the right of O gives T.

• One person sits between T and X, who faces the same direction as O (inside). Thus, X faces inside.

• K is not an immediate neighbour of X. So, placement around the circle is determined accordingly for K, L, R, O, T, X.

• The one who gets 16 marks sits second to the right of T but immediate left of the one who gets 25 marks. Since T = 27, second to the right of T is L (16 marks), and to L's immediate left is K (25 marks). This leaves X with 36 marks.

• Thus, the marks assigned to all persons are:

T = 27, R = 20, O = 18, L = 16, K = 25, X = 36.

4. Identify marks in ascending order:

1st lowest = 16 (L)

2nd lowest = 18 (O)

3rd lowest = 20 (R)

4th lowest = 25 (K)

5th lowest = 27 (T)

6th lowest = 36 (X)

The person with the 4th lowest marks is K (25 marks).

5. Find the person second to the left of K:

Based on the facing directions derived (K facing outside), counting two places to the left of K leads directly to R.

Therefore, the person sitting second to the left of the one who gets the fourth lowest marks is R.
