Sunday
Saturday
Friday
Wednesday
Explanation:

On 31st December, 2005 it was Saturday.
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.
2522.Which of the following is not a leap year?
700
800
1200

2523.If the first day of a year [other than leap year] was Friday, then which was the last day of that year?
Saturday
Friday
Tuesday
Monday
Explanation:

Given that first day of a normal year was Friday

Odd days of the mentioned year = 1 [Since it is an ordinary year]

Hence First day of the next year = Friday + 1 Odd day = Saturday

Therefore, last day of the mentioned year = Friday

2539.January 1, 2007 was Monday. What day of the week lies on Jan. 1, 2008?
Monday
Tuesday
Wednesday
Sunday
Explanation:

The year 2007 is an ordinary year. So, it has 1 odd day.

2540.What was the day of the week on 28th May, 2006?
Thursday
Friday
Saturday
Sunday
Explanation:

28 May, 2006 =2005 years + Period from 1.1.2006 to 28.5.2006

Odd days in 1600 years = 0

Odd days in 400 years = 0

5 years = 4 ordinary years + 1 leap year = 4 x 1 + 1 x 2 $\equiv$ 6 odd days

2541.Arun went for a movie nine days ago. He goes to watch movies only on Thursdays. What day of the week is today?
Wednesday
Saturday
Friday
Sunday
Explanation:

Clearly it can be understood from the question that 9 days ago was a Thursday

Number of odd days in 9 days = 2 [As 9-7 = 2, reduced perfect multiple of 7 from total days]

Hence today = Thursday + 2 odd days = Saturday

2543.On 8th Dec, 2007 Saturday falls. What day of the week was it on 8th Dec, 2006?
Sunday
Thursday
Tuesday
Friday
Explanation:

The year 2006 is an ordinary year. So, it has 1 odd day.

So, the day on 8th Dec, 2007 will be 1 day beyond the day on 8th Dec, 2006.

But, 8th Dec, 2007 is Saturday.

$\therefore$ 8th Dec, 2006 is Friday.

2545.If 1st October is Sunday, then 1st November will be
Saturday
Thursday
Wednesday
Tuesday
Explanation:

Given that 1st October is Sunday

Number of days in October = 31

31 days = 3 odd days

As we can reduce multiples of 7 from odd days which will not change anything

Hence 1st November = Sunday + 3 odd days = Wednesday

2546.If the seventh day of a month is three days earlier than Friday, What day will it be on the nineteenth day of the month?

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 = $\left(5 \times 3\right)$ $\equiv$ 1

97 years has 24 leap years + 73 ordinary years.

Number of odd days in 97 years $\left( 24 \times 2 + 73\right)$ = 121 = 2 odd days.

2549.If 25th of August in a year is Thursday, the number of Mondays in that month is

44306.January 1, 1992 was a Wednesday. What day of the week will it be on January 1, 1993
Tuesday
wednesday
Thusday
Friday
Explanation:

Solution:
As it is known, that
Number of days between 1st January 1992 and 1st January 1993 =
(366-1=365)days of the year 1992( as 1992 is completely divisible by 4, hence it is a leap year and that’s why February has 29 days)+
1 days of January 1993
= 365+ 1= 366
= 52 weeks + 2 odd days
Hence, number of odd days = 2
1st January 1993 will be the 2nd day beyond Wednesday.
So, the required day will be Friday.

44307.What was the day of the week on 2nd March, 1602?
Wednesday
thusday
Friday
Saturday
Explanation:

Given that,
4th June, 2002 = (Odd days in 1600 years+ 1601 years + period from 1st jan, 1602 to 2nd March, 1602)
Odd days in 1600 years=0
Odd days in 1601 year = 1
Number of days according to the months are
January = 31 days
February = 28 days
March = 2 days
Therefore, 31 + 28 + 2=30 = 4 weeks 2 days ≡ 2 odd day
Total number of odd days = 1 + 2 = 3
Therefore, required day is Wednesday.

44308.What day of the week did 30 june 1974 fall?
saturday
sunday
Monday
Tuesday
Explanation:

As known,
Number of odd days upto 30 june 1974 =
(odd days for 1600 years +
odd days for 300 years (Number of odd days in 300 years = (5 x 3) 1 odd day.)+
odd days for 73 years )
= 0 + 1 + ((18 x 2) + (1 x 55) )
= 0 + 1 + 0=1 odd days

odd days of 30 days of june 1974=
Number of days according to the months are
January = 31 days
February = 28 days
March = 31 days
April = 30 days
May = 31 days
June = 30 days
Therefore, 31 + 28 + 31 + 30 + 31 + 30 = 181 = 25 weeks 6 days ≡ 6 odd day
total odd days=1+6=7
Therefore ,30th june 1974 was a sunday.

44309.Will date-book for the year 2003 serve for the year 2014?
No
Yes
Explanation:

Sum of odd days from 2003 to 2013 should be zero.
From 2003 to 2013, no of odd days are 1,2,1,1,1,2,1,1,1,2,1 respectively.
Sum of odd days = 1+2+1 + 1 + 1 + 2 + 1 + 1+1+2+1 = 2 week 0 odd days.
So, both dates 1.1.2009 and 1.1.2015 will be on same day, so calendar for the year 2003 will serve for the year 2014.

44310.On what date of august, 1947 did Friday fall ?
8.8.1947
9.8.1947
10.8.1947
11.8.1947
Explanation:

For this find the day of 1.8.1947
number of odd days for 1600 years=0
number of odd days for 300 years=1
From 1991 to 1946, there are 11 leap years + 35 ordinary years.
So, number of odd days = 11 x 2 + 35 x 1=22+35=57=8weeks+1 odd days=1 odd day
Number of days according to the months are
January = 31 days=3 odd days
February = 28 days=0 odd day
March = 31 days=3 odd days
April = 30 days=2odd days
May = 31 days=3odd days
June = 30 days=2odd days
July =31 days=3odd days
August=1 day
Therefore, 3 + 0+ 3 + 2 + 3 + 2+3+1 =17=2 weeks+3 odd days
Total number of odd days = 1+1+3=5
So, 1.8.1947 will be Friday.
Now, Friday will be on 1.8.1947, 8.8.1947, 15.8.1947, 22.8.1947
