The query is asked in my recent interview and the same I want to share with you. If anyone has better solution(corrected by Sandeep Walia)  please share here:
declare @dt datetime
set @dt=’1/1/2010′ –Want to know January’s Last Monday Date
SELECT dateadd(d,-datepart(dw,DATEADD(d, -datepart(d,dateadd(mm,1,@dt)),dateadd(mm,1,@dt))-1)+1,DATEADD(d, -datepart(d,dateadd(mm,1,@dt)),dateadd(mm,1,@dt)))

I have also asked a tricky question like this:
Can we create a singleton class using public constructor?
Simply answer is yes.
Practically, many of us aware that we can create a singleton class by using private constructor an creating a property, but we can create a singleton class by using public constructor as folows:
static void Main(string[] args)
{
try
{
Singleton obj3 = new Singleton2();
Singleton obj4 = new Singleton2();
Console.Read();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
Console.Read();
}
}
static void Main(string[] args)
{
try
{
Singleton obj3 = new Singleton2();
Singleton obj4 = new Singleton2();
Console.Read();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
Console.Read();
}
}

A Lambda expression is nothing but an Anonymous Function, can contain expressions and statements. Lambda expressions can be used mostly to create delegates or expression tree types. Lambda expression uses lambda operator => and read as ‘goes to’ operator.
Left side of this operator specifies the input parameters and contains the expression or statement block at the right side.
Example: myExp = myExp/10;
Now, let see how we can assign the above to a delegate and create an expression tree:
delegate int myDel(int intMyNum);
…

Its can’t possible adding hyperlinks/links to listbox.
Its just a collection items not child items and are not render while anyone put some html tags. So, its not possible
