Find the angle between minute hand hour hand at 11 : 50 AM

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.

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

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.

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.

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

Same as previous question Option A is correct.

39°

At 2 PM angle between minute hand and hour hand is 60° and that at 6 PM is 180° hence percentage change is 200%.

From the formula the required angle is 187.5°
