What was the day of the week on 17th June, 1998?
Answer: Option
Explanation:
17th June, 1998 = (1997 years + Period from 1.1.1998 to 17.6.1998)
Odd days in 1600 years = 0
Odd days in 300 years = (5 x 3) 
1
97 years has 24 leap years + 73 ordinary years.
Number of odd days in 97 years ( 24 x 2 + 73) = 121 = 2 odd days.
Jan. Feb. March April May June (31 + 28 + 31 + 30 + 31 + 17) = 168 days
168 days = 24 weeks = 0 odd day.
Total number of odd days = (0 + 1 + 2 + 0) = 3.
Given day is Wednesday.

We can caluclate the number of leap years by dividing the given two digit nuber with 4.
Supose we will take the above problem if 98 is divided by the 4 then we will get the no. Of leap years which nothing but the multiple of four i.e. 24.
Then 97 - 24 = 73.
73 ordinary years and 24 leap years.

@Hi Shruthi,.
It is measured that each 100year has 5 odd days OK ?.
(remember it always don't ask why because this is not our main problem).
So, for 300years 5*3=15 odd days.
But 15 days are convert-able in weeks.
So, 15/7 = 2 weeks + 1 odd days.
(leave days for week, now they are not odd).
That's why 300years = 1 odd day.

499*2=899 = no of odd day in leap(for understand)
1996-499=1497 odd day in remaining year (for understand)
odd day 899+1497= 2396 total odd day (for understand)
2396/7= 342+ 2/7=> 2odd day (actual odd day till 1996)
2+1= 3 odd day till 1997 (actual odd day till 1997)
then 1 Jan 1998= thursday
