Every 4th year may not be a leap year because the year which is divisible by 100 then that year is know as leap year or leap centenary.

Not each 100 years contain 24 leap year and 76 ordinary years.
For example: 1900-2000 contain 25 leap year and 75 ordinary years.

100 is divided by 4we will get 25. But 100 is not a leap year. So we have only 24 leap years and 76 ordinary years.

Why we have taken friday as a 5 odd days of last day of 100 century, why not other days like sunday, mondey etc.

It's so simple. 100/7=14 and remainder is 2. So,
0=Sunday.
1=Monday.
2=Tuesday.
So it cannot be Tuesday (2).
0=Sunday.
1=Monday.
2=Tuesday.
So it cannot be Tuesday (2).

100 years contains (366*25)+(365*75)=36525 days.
So 36525/7 = 6 odd days but it is given 5 odd days. How?
