Solution

At least two but not more than four people sitting on each edges of the table.  P sits at one of the corner. The one whose age is 36 years, sit second to the left of P. T is 36 years old. Same Number of people seated in opposite edges. S whose age is 52 sits sixth to the right of the one whose age is 10 less than S and both of them are immediate neighbor of the person sitting at the corner. Neither P nor T is an immediate neighbor S. We cannot fix the position of S and the one whose age is 42 in case2, so this case is eliminated. W sits third to the left of S. R sits sixth to the left of W. The one whose age is 44 sit second to the right of the one who is sitting opposite to R. U is an immediate neighbor of the one whose age is 44. The one who is 48years old sits fourth to the right of U. The age of P is equal to half of the age of V. Number of person sits between P and R when counted from left of P is equal to number of person sit between R and the one whose age is 30.
