Study the following information carefully and answer the questions given below. Eight persons -A, B, C, D, E, F, G and H were born in different years i.e. 1991, 1995, 2002, 1998, 1985, 2018, 2015 and 2010 but not necessarily in the same order. 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.

Question: How many persons were born between C and the one whose age is 11 years?
