Direction : Study the following information carefully and answer the questions given below:
Seven persons i.e. P, Q, R, S, T, U, V of different ages i.e. 6, 15, 19, 23, 30, 45, 60 years are sitting in a circular table facing towards center.
Note- No two consecutive letters are in alphabetical order. Person’s age must not be a factor or a multiple of sum of the ages of their immediate neighbors.
R sits immediate right of the person whose age is 15. One person sits between T and R (either left or right). One person sits between P and the person whose age is 6 (either left or right). Age of T is twice the age of the person who sits 2nd to the right of T. Difference between the age of the immediate neighbors of V is more than 14. Age of U must not be multiple of 10. Sum of the ages of immediate neighbors of R is 34. Q is younger than P.
Who among the following sits 2nd to the left of the person whose age is 19 years?
- A.
U
- B.
V
- C.
P
- D.
Q
- E.

Correct answer: A
Concept
When people sit around a circle facing the centre, each person's right hand points anti-clockwise and the left hand points clockwise, so "immediate right" is the next seat anti-clockwise and "immediate left" the next seat clockwise. The reliable method is to turn each clue into a fixed link or a numeric test, lock the most restrictive numeric clue first, then keep applying the positional and "factor / multiple" rules until exactly one circle survives.
Building the arrangement
R's neighbours sum to 34. Checking every pair of the seven ages, the only pair totalling 34 is 15 and 19, so R sits directly between the persons aged 15 and 19.
R is the immediate right of the person aged 15, which fixes the order of the block; R's own age cannot be 15 or 19 (those are its neighbours), and testing the rest against "a person's age is not a factor or multiple of the neighbours' sum 34", only 45 keeps R valid (34 is neither a factor nor a multiple of 45), so R = 45.
"T's age is twice the age of the person 2nd to his right." Among the ages the only exact 2 : 1 pair available for that gap is 60 and 30, so T = 60 with the 30-year-old two seats to T's right; "one person sits between T and R" then fixes T's distance from the R-block.
"One person sits between P and the 6-year-old" places P, while "no two alphabetically consecutive letters are adjacent" forbids P–Q, Q–R, R–S, S–T, T–U and U–V from sitting together, and "Q is younger than P" sets Q below P; together these allow only one ordering around the block.
Finally "the difference of V's two neighbours' ages exceeds 14" and "U's age is not a multiple of 10" remove every remaining alternative, leaving the single circle below.
The unique circle (reading clockwise, facing centre)
Seat (clockwise) | Person | Age |
|---|---|---|
1 | U | 15 |
2 | Q | 6 |
3 | S | 30 |
4 | P | 23 |
5 | T | 60 |
6 | V | 19 |
7 | R | 45 |
Answer
The person aged 19 is V. "Left" is clockwise when facing the centre, so moving clockwise from V the 1st-left seat holds the 45-year-old and the 2nd-left seat holds the 15-year-old, who is U. Hence U sits 2nd to the left of the person aged 19.
Cross-check
R's neighbours are 15 and 19 (sum 34 ✓); T = 60 is twice the 30-year-old two seats to its right ✓; V's neighbours are 45 and 60, differing by 15 ( > 14 ✓); U is 15, not a multiple of 10 ✓; and no two alphabetically consecutive letters sit together ✓ — every clue holds, confirming U.
