Read Solution (Total 8)
-
- my solution is the most easiest one
to know the day first we have to find the no of odd day.
to find the odd day we have to find the total days in between
from jan 1 to june 11
it is 31+28+31+30+31+11=162 days
162/7= 1 odd day(it is the remainder)
now from jan 2001 to dec 2012
12 years which has 3 leap year and 9 ordinary years
so total odd days in this 12 years is 3*2+1*9= 15 odd days
from july 11,2000 to dec 31 2000
no of days=20+31+30+31+30+31=173days
173/7=5 odd days
total no of odd days=
1+15+5=21 odd day
21/7=0 odd day
so the ans is monday - 11 years agoHelpfull: Yes(2) No(0)

Explanation:
There is 5 odd days b/w july 11,2000 to dec31,2000. Again there is 1 odd day b/w jan 1,2001 to dec 31,2012(3 leap yrs has 6 odd days nd 9 ordinary yrs has 9 odd days i.e. 15 odd days=1 odd day). Now from Jan 1,2013 to June 11,2013 there is 1 odd day. so the total no of odd days=5+1+1=7=0 odd days. - 11 years agoHelpfull: Yes(1) No(0)
