If 1st Jan 2001 is Monday then which day was on 1st Jan 2013.

Correct Answer: Saturday

Explanation:

Number of days in June is 30 -2 = 28, and number of days in July is 7, total number of days is 28 + 7 = 35, when we divide 35 by 7 remainder is 0, or number of odd days is 0 hence 7th July must be the same day as that of 2nd June i.e. Saturday in this case.

Correct Answer: Wednesday

Explanation:

Since in 1 year we have one odd day while in one leap year we have two odd days .
Number of odd days are: 1(for 2006) + 1(for 2007) + 2 (For leap year 2008) + 1 (for year 2009) so total number of odd days are 1 + 1 + 2 + 1 = 5 days. 5 days more than Friday means Wednesday.

Correct Answer: Thursday

Explanation:

Since a day of the week repeat after every 7 days, divide 59 by 7, remainder is 3 so number of odd days is 3, and 3 days after Monday is Thursday.

Correct Answer: Saturday

Explanation:

Since in 1 year we have one odd day while in one leap year we have two odd days.
Number of odd days are 1 (for 2006)
1 days more than Friday means Saturday.

Correct Answer: 9 : 441/11

Explanation:

Consider exactly at 9 : 00, minute hand is at position '12' and hour hand is at '9' hence angle between these two hands at 9 : 00 is 270°
Since relative speed between them is 11/2° per minute or every minute hand will travel 11/2° more than the hour hand.
Then will be perpendicular to each other when the minute hand will travel 270° more than the hour hand. And time taken for this is (270)/(11/2) = 540/11 or 49 1/11 minute
Hence they will be perpendicular to each other at 9 : 49 minute : 0.09 second

Correct Answer: 2100

Explanation:

The century divisible by 400 is a leap year. 2100 is not divisible by 400 hence is not a leap year.

Correct Answer: 1128

Explanation:

The century divisible by 400 is a leap year. 2100 is not divisible by 400 hence is not a leap year so 2100 is not a leap year, out of remaining 1128 is divisible by 4, so 1128 is a leap year.

Correct Answer: None of these

Explanation:

On 31^st December, 2005 it was Saturday.
Number of odd days from the year 2006 to the year 2009 = (1 + 1 +2 + 1) = 5 days.
? On 31^st December, 2009, it was Thursday.
Thus, on 1^st Jan, 2010 it is Friday.

Correct Answer: Saturday

Explanation:

When 69 is divided by 7 we will get remainder 6 so the day will be 6 days more than Sunday i.e Saturday.

Correct Answer: None of these

Explanation:

Number of odd days between 6^th march 2002 to 6^th march 2003 is 1
Number of odd days between 6^th march 2003 to 6^th march 2004 is 2
Number of odd days between 6^th march 2004 to 6^th march 2005 is 1
Hence total Number of odd days between 6^th march 2002 to 6^th march 2005 is 1 + 2 + 1 = 4 odd days so 6^th march 2002 is 4 days before Sunday i.e. Wednesday.
