• 15th Aug.2010 mean(2009 completed years and Ist April 2010 to 15th Aug.2010)
  Now, we are going to calculate odd days
  For every 400 years, the odd days are zero
  Hence for 2000 years the odd days are zero
  For Balance 9 years, there are 2 leap years and 7 ordinary years
  and hence the no of odd days ar 2*2+7*1=11 and it can be reduced to 4 odd days
  Hence for 2009 years the total No. of odd days=0+4=0
  Now Again we have to calculate the odd days in different Months(up to 15th Aug)
  Month Jan. Feb. Mar. Apr. May Jun. July Aug.(up to 15th)
  No of odd days 3 0 3 2 3 2 3 1
  Thus total no. of odd days are=17( it can be reduced to 3 odd days)
  Thus In total, we have arrived 4+3=7odd days which is equivalent to 0 odd days
  And 0 odd days correspond to Sunday(option A)
