On what dates of April, 2001 did Wednesday fall?
Answer: Option
Explanation:
We shall find the day on 1st April, 2001.
1st April, 2001 = (2000 years + Period from 1.1.2001 to 1.4.2001)
Odd days in 1600 years = 0
Odd days in 400 years = 0
Jan. Feb. March April
(31 + 28 + 31 + 1) = 91 days 
0 odd days.
Total number of odd days = (0 + 0 + 0) = 0
On 1st April, 2001 it was Sunday.
In April, 2001 Wednesday falls on 4th, 11th, 18th and 25th.

Guys it is easy to find solution to this problem by formula.
Day = Date+Month code+(x-1990)+(x-1990)/4.
Here given day is Wednesday it's code is 4 so now 4 = Date+0+101+25.
4 = Date+126.
You should get (date+126)/7 you should get 4 by trail and error method if you substitute any one day you will know the answer.

@Masthan.
Please explain this. It's very short. But how to do this?
x+2+1+25+6 = 3.
x+34-3 = 0.
x+31 = 0.
x+28+3 = 0 (28/7 = 0).
x+3 = 0.
4+3 = 7 = 0 (7/7 = 0).
x = 4, 11, 18, 25.

Why do they take 1600 and 400 every time they solve a problem and in some case 300 years and 1600?

When to take 28 days or 29 days in (31+28+31+1) means when will we take 29 in place of 28?

Can someone explain why we also added 1 April.
Why (31+28+31+1) =91.
And why not (31+28+31) = 90 because we have to find no of odd days before April so that we can find day on 1 April.
