Question

9. 29th April 2004 was a Monday. What day of the week was 19th January the same year?

Answer 1

Sᴏʟᴜᴛɪᴏɴ :-

29 April 2004 = Monday.

19 January 2004 = ?

Lets Start from jan .

→ Total odd Days = 11(Left jan.) + 29(Feb. As 2004 is Leap Year) + 31(March) + 29(April) = 4 + 1 + 3 + 1 = 9 = 2 .

Now, As we have to go back ,

→ Monday - 2 = Friday.

Hence, on 19th Jan the same year it was Friday.
