Mike's number is 2000 more than Jerry's which is 400 less than Barry's. Larry's number is 1500 more than Sam's, which is 443. Sam's number is 60 less than Barry's.

Jerry's number = n.
Mike's number = n+2000
Barry's number = n+400.
Larry's number = 443+1500 = 1943.
Sam'2 number = 443.
Barry's number = 443+60 = 503.
n+400 = 503
n = 103
n+2000 = 103+2000 = 2103
