B works with F and having retirement in 2035. All persons must work 58 years from the year of joining so B joined the department in 1977.

D works in Customs and has experience which is equal to the sum of the work experience of A and B. Another one who joined customs in 2011 so he had an experience of 8years. Difference between the joining years of B and C is equal to the experience of the one who gets retirement in 2069. Then difference is 8 so C joined in 1985. C joins after B.

E works with same department as the one who has high experience in the group. Sum of the work experience of both E and C is equal to the working experience of B From the statement we got E had 8 year and he works in the Customs. One whose joining year is 1999 was works in the same department with neither A nor E.  From above statement we assume that there is no possible for A then it has to gone with option F only. A had less experience than F. One who joins in 1985 is not work with D. Then possible case is A was joined in 2005.

D works in Customs and has the experience which is equal to the sum of A and B works experience. One who has 14 year experience is neither working in Customs nor Transports. The difference between the work experience of A and C is equal to the work experience of F.  The difference between the joining year of A and F is two less than the work experience of E in Customs.
