  $("#chk1").click(function() {
    $("#chk3").checked(true);
  });
});

Try:-

XML

<asp:CheckBox ID="chk1" onclick="chkSlct();" runat="server" Text="IAS" />
 <asp:CheckBox ID="chk2" runat="server" Text="PCS" />
        <br />
        <br />
        <br />
        <br />
        <asp:CheckBox ID="chk3" runat="server" Text="This is IAS" />
 <asp:CheckBox ID="chk4" runat="server" Text="This is PCS" />

function chkSlct() {

        if (document.getElementById("<%=chk1.ClientID%>").checked == "true") {
            document.getElementById("<%=chk3.ClientID%>").checked = true; 
        }

    }

Catch the click event of the chk1 using javascript, and in that event, you should write the code through which you can 'check' the value of chk3 checkbox. for example

checkBox1Checked()
{
chk3.checked = true;
}

You can call bind this with the checkbox1 as
<asp:checkbox onclick="javascript:checkbox1Clicked();" id="chk1" runat="server" text="IAS" xmlns:asp="#unknown" />

Note: remove xmlns:asp="#unknown" from above line. I don't know why it is getting added here.
