[Tex/LaTex] Citing example from same book- different pages

bibtex

I need to cite different examples from different pages of the same book. How can I do it. How can I cite example from same book that are in different pages?
For example.

I need the citation in following form
enter image description here

enter image description here

@article{10.2307/4178405,
 ISSN = {00243892, 15309150},
 URL = {http://www.jstor.org/stable/4178405},
 author = {K. P. Mohanan},
 journal = {Linguistic Inquiry},
 number = {4},
 pages = {575-602},
 publisher = {The MIT Press},
 title = {Lexical Phonology of the Consonant System in Malayalam},
 volume = {15},
 year = {1986b}
}

Such things are typically added using the optional argument of the citation command. You don't say anything about your setup, here is an example with natbib:

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{mohanan1986b,
 ISSN = {00243892, 15309150},
 URL = {http://www.jstor.org/stable/4178405},
 author = {K. P. Mohanan},
 journal = {Linguistic Inquiry},
 number = {4},
 publisher = {The MIT Press},
 title = {Lexical {P}honology of the {C}onsonant {S}ystem in {M}alayalam},
 volume = {15},
 year = {1986b}
}
\end{filecontents*}

\usepackage{natbib}
\setcitestyle{numbers,notesep={: }}
\begin{document}

\cite[86--88]{mohanan1986b} or \cite[186--198]{mohanan1986b}

\bibliographystyle{alpha}
\bibliography{\jobname}

\end{document}

enter image description here

Note that with numerical styles (such as alpha) you should only use \cite. With author-year citations, as shown in your image, you need \citet[7-42]{citekey} to get an output of the form Author (year, pages). For example:

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{mohanan1986b,
 ISSN = {00243892, 15309150},
 URL = {http://www.jstor.org/stable/4178405},
 author = {K. P. Mohanan},
 journal = {Linguistic Inquiry},
 number = {4},
 publisher = {The MIT Press},
 title = {Lexical {P}honology of the {C}onsonant {S}ystem in {M}alayalam},
 volume = {15},
 year = {1986b}
}
\end{filecontents*}

\usepackage{natbib}
\setcitestyle{round,notesep={: }}
\begin{document}

\citet[86--88]{mohanan1986b} or \citet[186--198]{mohanan1986b}

\bibliographystyle{plainnat}
\bibliography{\jobname}

\end{document}
