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.

Answer 1

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
