It was Sunday on Jan 1, 2006. What was the day of the week Jan 1, 2010?
Answer: Option

Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.
On 31st December 2009, it was Thursday.
Thus, on 1st Jan, 2010 it is Friday.

@Boomathi.
We know the given year is leap year or not, that year is divided by 4. That number (year) does not give any remainder that year is called leap year.

Hi there is a formula for this type of problem.
Plz memorize this
jan=1
feb=4
mar=4
apr=0
may=2
jun=5
jul=0
aug=3
sep=6
oct=1
nov=4
dec=6
days:
s=1
m=2
t=3
w=4
th=5
f=6
sat=7 or 0
formula=day+mon no.+(x-1900)+(x-1900)/4
x= the year we have to calculate
Eg:
16-may-2011
for=16+2+(2011-1900)+(2011-1900)/4
=16+2+111+111/4
=16+2+111+27
(here we should not take the no behind decimal i.e 111/4=27.75)
=156
156/7=2(reminder)
mon =2

For non-leap year odd number = 1 .
For leap year odd number = 2.
For leap year odd number = 2.
