Correct option is A
Given:
15 March 2022 was a Tuesday
As we know that odd day in a normal year = 1
Year 2021 is a normal year
Thus, on 15 March 2021 will be Monday.
Year 2020 is Leap Year but we count till 15 March.
Thus, the total odd day between 15 March 2021 to 15 March 2020 = 2
Therefore on 15 March 2020 will be Sunday.
