What day of the week was 1st January 1901
A. Monday
B. Tuesday
C. Wednesday
D. Thursday
Answer: Option B
Solution (By Examveda Team)
1st 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.
