Answer 2

Given,

The day of the week on which 18 February 2005 falls is Friday.

To Find,

The day of the week on which 18 February 2007 falls.

Solution,

The number of days between 18 February 2005 and 18 February 2006 = 365

The number of days between 18 February 2006 and 18 February 2007 = 365

The total number of days between 18 February 2005 and 18 February 2007 = 730

On Dividing the total number of days by the number of the days in a week,

⇒$\frac{730}{7}$

⇒$104+2$( 2 is the remainder)

The remainder 2 indicates that the day of the week on which 18 February 2007 falls is 2 days after Friday, that is Sunday.

Henceforth, 18 February 2007 is Sunday.
