Text box is html tag input of type text. It don't have text attribute.
It have value attribute. So:

JavaScript

var val = (abc/ efg)*100;
    document.getElementById("<%=txt1.ClientID%>").value= val;

That should working fine.

And hint: Use firebug (FF), developer tools (IE), OperaDragonfly etc. to check JS errors of you code. This will save you tons of time.

You're so very close. Change this:

JavaScript

var val = (abc/ efg)*100;
    document.getElementById("<%=txt1.ClientID%>").text = val;

to this:

JavaScript

var val = (abc/ efg)*100;
    document.getElementById("<%=txt1.ClientID%>").value = val;
