What will be the day of the week 15th August, 2010?
Answer: Option
Explanation:
15th August, 2010 = (2009 years + Period 1.1.2010 to 15.8.2010)
Odd days in 1600 years = 0
Odd days in 400 years = 0
9 years = (2 leap years + 7 ordinary years) = (2 x 2 + 7 x 1) = 11 odd days 
4 odd days.
Jan. Feb. March April May June July Aug. (31 + 28 + 31 + 30 + 31 + 30 + 31 + 15) = 227 days
227 days = (32 weeks + 3 days) 3 odd days.
Total number of odd days = (0 + 0 + 4 + 3) = 7 0 odd days.
Given day is Sunday.

@All.
It is simple, zero refers to Sunday in calendar rule, Monday = 1, same as if the total number of odd days is 6 it's your Saturday.

I have a question.
How in 100 years, 76 was ordinary years and 24 was leap years?
Because generally, every 4 year is a leap year, so 100 is completely divisible by 4 and we get 25, so in general, in 100 years, there were 25 leap years?
Please, anyone, explain this to me.

2+(10/12)+rem(10/12)+(rem(10/12)/4).
2+0+10+2 = 14.
2+0+10+2 = 14.

@Poonam.
1600 & 400 are reference years with which we calculate the solution. As they leave 0 odd days. So we can calculate fresh.

Why are we taking 1600 or 400?
How do we know what is the year code?
What is the basis of codes?
How are the codes arrived at?
Is there any formula or reasoning for arriving at the different codes for the Months, Days and a particularly century?
