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.Correct Option: D

At 11 : 50 A.M. from the formula here P = 11 and Q = 50 so required angle is 11 x 50/2  30 x 11 = 275  330 = 55 or ignoring the negative sign the required angle is 55°
