Read the information carefully and answer the question given below. Fourteen persons sit in two parallel rows containing seven persons each. In row 1, A, B, C, D, E, F and G are seated and all of them face north. In row 2, P, Q, R, S, T, U and V are seated and all of them face south, but not necessarily in the same order. Persons of row 1 face the persons of row 2. Q sits two places away from the one who faces E. E is the only immediate neighbour of D. U faces the one who sits third to the right of C. The number of persons sitting to the right of Q is the same as the number of persons sitting to the left of G. B sits second to the left of G. One person sits between R and V, and both of them do not sit at the extreme ends. S sits to the right of T but does not sit at an extreme end. A faces the one who sits second to the right of R. Which of the following statement(s) is/are true?
- A.
Two persons sit between G and A
- B.
U faces E
- C.
V sits to the left of R
- D.
C does not sit at an extreme end
- E.
All are true

Show answer & explanation
Correct answer: E
Concept
In a two-parallel-row arrangement, the two rows face each other, so 'left' and 'right' are mirror-reversed between them. A clue of the form 'X sits k-th to the right of Y' is read along each row's own facing direction, and 'P faces Q' means P and Q occupy the same column (one in each row). To pick a 'which statement is true' answer you must first FIX the whole layout, then test EVERY statement before choosing.
Building the arrangement
B sits second to the left of G, and the count of persons to the right of Q (row 2) equals the count to the left of G (row 1); together these pin G's column and place B two seats to its left.
E is the ONLY immediate neighbour of D, so D must sit at an extreme end with E next to it.
U faces the person third to the right of C, and 'Q sits two places from the one who faces E' fix Q and U in row 2.
'One person sits between R and V, neither at an end', 'S is right of T, not at an end', and 'A faces the person second to the right of R' lock the remaining seats.
Applied in turn, these clues pin every seat, so the arrangement is uniquely determined:
Position (L to R) | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
Row 1 (North) | A | B | C | G | F | E | D |
Row 2 (South) | P | S | R | Q | V | U | T |
Facing pairs (same column): A-P, B-S, C-R, G-Q, F-V, E-U, D-T.
Testing each statement
Two persons sit between G and A: A is at the left end and G is fourth from it, so B and C sit between them - exactly two. TRUE.
U faces E: E and U share the sixth column, so they face each other. TRUE.
V sits to the left of R: in row 2 both lie on the same side, with V farther from R's facing-right, so V is to R's left. TRUE.
C does not sit at an extreme end: C is in the third seat of row 1, an interior seat. TRUE.
Result
Every one of the four statements holds in the unique arrangement, so the statement that all of them are true is the one that is correct.
