How to show chapterNo/TotalChapterCount in the Chapter title of memoir document.
\documentclass{memoir}
\usepackage{lipsum}
\begin{document}
\tableofcontents
\chapter{First}
\lipsum
\chapter{Second}
\lipsum
\end{document}
I want the chapter title as
Chapter 1/2 First
I dont need any changes in tableofcontents.
Just an addition to Milos answer, the same in just memoir
\documentclass{memoir}
\usepackage{lipsum}
\usepackage{totcount}
\regtotcounter{chapter}
\renewcommand\printchapternum{\chapnumfont \thechapter/\total{chapter}}
\begin{document}
\tableofcontents
\chapter{First}
\lipsum
\chapter{Second}
\lipsum
\end{document}
You'll need to adapt it to what ever chapter style you are using.
Disclaimer: This isn't a pure memoir solution as it uses the titlesec package to customise the appearance of the titles. Also, thanks to @egreg for pointing out that titlesec and memoir don't always play well together. See About memoir and titlesec incompatibility. For a memoir solution see the answer of @daleif.
Using the totcount package (as described in How to get the number of chapters in a document).
\documentclass{memoir}
\usepackage{lipsum}
\usepackage{titlesec}
\usepackage{totcount}
\regtotcounter{chapter}
\titleformat{\chapter}[display]
{\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter/\total{chapter}}{20pt}{\Huge}
\begin{document}
\tableofcontents
\chapter{First}
\lipsum
\chapter{Second}
\lipsum
\end{document}
