If 13 January 2006 is a Friday, then what will be the day of the week on 28 March 2008?

Friday

Using Code Method :-

\(\frac{Date+Month code+Year code+Last 2 digits of yr+Leap yrs till given yr}{7}\)

( Note: Remainder of the above sum will be the code of week day }

13 Jan 2006;

13 + 01 + 06 + 06 + 01 = 27

remainder of \(\frac{27}{7}\) = 06

Therefore, the code of 06 is Friday

Similarly,

28 March 2008;

28 + 04 + 06 + 08 + 02 = 48

remainder of \(\frac{48}{7}\) = 06

Therefore, the code of 06 is Friday
