Person whose age is 25 sits 3rd to the left of B who sits right of S. Sum of the ages of A and C is equal to the age of B whose age is divisible by 11. C and D have odd numbered ages. No one is younger than 15 and older than 41. Both oldest and youngest persons are immediate neighbours of P. So, B is 33 years old. Now, C and D are youngest and oldest person. A is 2nd youngest person. So, Age of A and C is 18 and 15 respectively. Now D is oldest person and his age is odd numbered, so his age is 41. Average of the ages of A, C and S is 18.
