Thanks everyone , finally was left with no option but to do a math , perl would not have been an ideal scenario because this is just one part of the whole script,
here is what I came up with finally
Code:
no_of_lines=`wc -l < ${WORK_FILE}`
no_of_files=`expr $no_of_lines / 12`
echo "File is Present .Splitting the file into n number of files"
split -d -l $no_of_files ${WORK_FILE} $TARGET_FILE
if [[ -r split_newfile_12 ]] ; then 
  cat split_newfile_12 >> split_newfile_11
  rm split_newfile_12
fi

split(1)							   User Commands							  split(1)

NAME

       split - split a file into pieces

SYNOPSIS

       split [-linecount | -l linecount]  [-a suffixlength] [ file [name]]

       split [ -b  n | nk | nm] [-a suffixlength] [ file [name]]

DESCRIPTION

       The  split  utility reads file and writes it in linecount-line pieces into a set of output-files. The name of the first output-file is name
       with aa appended, and so on lexicographically, up to zz (a maximum of 676 files). The maximum length of name is 2 characters less than  the
       maximum	filename length allowed by the filesystem. See statvfs(2). If no output name is given, x is used as the default (output-files will
       be called xaa, xab, and so forth).

OPTIONS

       The following options are supported:

       -linecount | -l linecounNumber of lines in each piece. Defaults to 1000 lines.

       -a suffixlength	       Uses suffixlength letters to form the suffix portion of the filenames of the split file. If -a  is  not	specified,
			       the  default suffix length is 2. If the sum of the name operand and the suffixlength option-argument would create a
			       filename exceeding NAME_MAX bytes, an error will result; split will exit with a diagnostic  message  and  no  files
			       will be created.

       -b n		       Splits a file into pieces n bytes in size.

       -b nk		       Splits a file into pieces n*1024 bytes in size.

       -b nm		       Splits a file into pieces n*1048576 bytes in size.

OPERANDS

       The following operands are supported:

       file	The path name of the ordinary file to be split. If no input file is given or file is -, the standard input will be used.

       name	The  prefix  to  be used for each of the files resulting from the split operation. If no name argument is given, x will be used as
		the prefix of the output files. The combined length of the basename of prefix and suffixlength cannot exceed NAME_MAX  bytes.  See
		OPTIONS.

USAGE

       See largefile(5) for the description of the behavior of split when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of split: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
