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.

If number exist between 2000 to 2099 then apply formula like
Example 5 april, 2020.
1) Take last 2 digit 20
2) 20+20/4-1=>20+5-1=>4
3) Follow this series
0 For jan
3 For feb
3 For mar
6 For april
1 For may
4 For june
6 For july
2 For aug
5 For sep
0 For oct
3 For nov
5 For dec
4) Check the code for april= 6 that means month=6 then date=gives a date in question like 5
5)(y+m+d) mod 7 (mod means take remainder)
6)(24+6+5)mod 7=>35mod 7=>means 0 Sunday.

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.

Shortcut:
From 0(AJ),1(JO),2(My),3(Ag),4(FMrN),5(Jn)6(SD).
And 1-S,2-M,3-T,4-W,5-TH,6-FR,7 or 0- Sat.
finding day on 1/4/2001.
1+0+(2001-1900)+(2001-1900)/4.
1+0+101+25 ; 101/4=25.25 take the whole number (25 only).
127/7=18 reminder 1 which represents day Sunday.
This means that if Sunday is 1 then Wednesday is 4 therefore,
Option D is right.

Check all options and do verification by finding the day of 1st april (31+28+31+1) = 91 hence 91/7 = 13 remainder 0 therefore 1st april is sunday.
