Solution (By Examveda Team)

9^th May, 2001 = (2000 years + Period from 1.1.2001 to 9.5.2001)
Odd days in 1600 years = 0
Odd days in 400 years = 0
Jan.   Feb.   March   April   May
(31 + 28 + 31 + 30 + 9) = 129 days
129 days = (18 weeks + 3 day) = 3 odd day
Total number of odd days = (0 + 0 + 3 ) = 3 odd day
Given day is Wednesday
