Question

1 January 2001 is Monday then what will 31 December 2001

Answer 1

Given :- If 1st January 2001 was Monday, then what day of the week was it on 31st December, 2001 ?

Solution :-

we know that,

• Odd day :- Remainder we get, when we divide number of days by 7.
• In a simple year we have = 365 days.

So,

→ 1st January 2001 to 31st December 2001 = 364 days. { since 2001 is not a leap year, 365 - 1st jan.}

then,

→ Odd days = 364 / 7 = 0 Remainder .

therefore,

→ 31st December 2001 = Monday + 0 = Monday

Hence, On 31st December 2001 it was Monday.
