Calculate the age of each person taking the base year 2021. B’s age is a prime number. There is four years gap between B and H. Two persons were born between B and E who was born in odd numbered year. The number of persons born before E is same as the number of persons born after F. G’s age is a multiple of 3 but less than B. The difference between the age of A and D is neither even nor prime number. C’s age is more than E’s age but not less than F’s age. E is older than F.
