Add Space between text in same line

[Ashish Kulkarni]

Hi

I want a text like below

ABC
        KLM

I want ABC to be at start of line and KLM at end,

I have tried

<fo:block font-size="7pt">
  ABC<fo:inline text-align="end" padding-before="15cm"> KLM</fo:inline>
  </fo:block>
But still when i print PDF i get ABC and KLM without space in between
