Eight persons A, B, C, D, E, F, G, and H were born in different years viz. 1963, 1967, 1973, 1979, 1984, 1989, 1992, and 1999 but not necessarily in the same order. It is assumed that all of them were born on the same date of different years. All the age calculations are done taking the base year as 2020. H was born immediately before G. There is a gap of six years between the years in which C and D were born. D is younger than C. The sum of ages of E and F is 57. The age difference between A and B is four years. E is younger than H. A is older than B.
