Difference between the ages of R and S is the same as the number obtained by dividing ages of any of the other five persons. Age of P is greatest amongst those whose age is a multiple of five. T is older than V who is not the youngest. Q is not youngest person.
Q. Study the following information carefully and answer the question given below:
Eight persons M, N, O, V, W, X, Y and Z attend seminars on different months of the year viz.
