Solution:
As 1993 was not a leap year, number of odd days in 1993 = 1
25th February 1993 = Thursday
Thus, 25th February 1994 = Thursday + 1 = Friday
Number of days from 25th February 1994 to 1st May 1994 = 3 + 31 + 30 + 1 = 65
Total number of odd days remainder of 65 ÷ 7 = 2 odd days.
So, the day on 1st May 1994 = Friday + 2 days = Sunday
Hence, Sunday is the correct answer.
