Question : Directions: If 31 January 2022 was a Monday, what was the day on the same date 100 years ago?
Option 1: Wednesday
Option 2: Sunday
Option 3: Tuesday
Option 4: Monday
Correct Answer: Tuesday
Solution :
Given:
31 January 2022 is a Monday.
The number of odd days in a leap year = 2
The number of odd days in a non-leap year = 1
Number of leap years between 2022 and 1922→25
Number of non-leap years between 2022 and 1922→75
Let's calculate the number of odd days→(25 × 2) + (75 × 1) = 50 + 75 = 125
Dividing 125 by 7, the remainder is 6.
Thus, 31 Jan 1922 will be = Monday – 6 = Tuesday
So, 31 Jan 1922 is Tuesday. Hence, the third option is correct.
