Try this one:

myString = "<em>Rs</em> 154,451. Hello world";
output = myString.replace(/<em>Rs<\/em>\s*(\d+(?:,\d+)?)/g, "<b>Rs $1</b>");

You can use () to capture a match and later use it in the replace:

var s = "<em>Rs</em> 154,451. Hello world";
s.replace(/<em>Rs<\/em>([^.]+)/, '<b>Rs$1</b>')
