1 Jan 1901 = (1900 years + 1st Jan 1901)
We know that number of odd days in 400 years = 0
Hence the number of odd days in 1600 years = 0 (Since 1600 is a perfect multiple of 400)
Number of odd days in the period 1601 - 1900
= Number of odd days in 300 years
= 5 x 3 = 15 = 1
(As we can reduce perfect multiples of 7 from odd days without affecting anything)
1st Jan 1901 = 1 odd day
Total number of odd days = (0 + 1 + 1) = 2
2 odd days = Tuesday
Hence 1 January 1901 is Tuesday.

Given date: 1 January 1901
To find the day of the week on this date, we can use the following steps:
Step 1: Find the number of days between the given date and the reference date (which is usually taken as 1 January 1900 or 1 January 2000, depending on the century).
Number of years between 1900 and 1901 = 1
Number of leap years between 1900 and 1901 = 0 (since 1900 is not a leap year)
Number of days in 1900 (from 1 Jan to 31 Dec) = 365
Total number of days between 1 Jan 1900 and 1 Jan 1901 = 365 + 1 = 366
Step 2: Divide the total number of days by 7 and find the remainder.
366 ÷ 7 = 52 remainder 2
Step 3: Assign a day of the week to the remainder, using a reference table.
The reference table is as follows:
0 - Sunday
1 - Monday
2 - Tuesday
3 - Wednesday
4 - Thursday
5 - Friday
6 - Saturday
Since the remainder is 2, the corresponding day of the week is Tuesday.
Therefore, the answer is option (b) Tuesday.
