Answer 1

Sᴏʟᴜᴛɪᴏɴ :-

Lets first find , day of first of April, 2001.

→ 1 April = 31 jan + 28 feb + 31 march + 1 April = 31 + 28 + 31 + 1 = 3 + 0 + 3 + 1 = 7 = 0 odd day.

Similarly,

→ 2001 = 2000 + 1 April = 0 + 0 = 0 odd day Total.

Therefore, we can conclude that, on 1 April, 2001 it was sunday.

Now,

→ 1 April , 2001 = Sunday.

→ 2 April , 2001 = Monday.

→ 3 April , 2001 = Tuesday.

→ 4 April , 2001 = wednesday. = First.

Hence,

→ 4 + 7 = 11 April , 2001 = wednesday = Second .

→ 11 + 7 = 18 April, 2001 = wednesday = Third.

→ 18 + 7 = 25 April, 2001 = wednesday = Fourth.

Correct Answer is Option (D) 4th, 11th, 18th, 25th.
