Hi Teja,  I was able to do this in Rapidminer Studio v10.  I used two Read CSV Operators for reading data.  Then I used two Generate Attribute Operators and added an id field wit value of one (1).  Then I added an Inner Join Operator and joined Id from both tables.  Finally I added a Generate Attribute Operator and divide data in one column with another column.  Please see screenshots below:

Hi @Teja_Varanasi,

one option is using the loop attributes operator combined with the extract Macro operator. 

The idea is to use the extract Macro operator to extract the value of the second example set and then use it to operate over the first exampleset. 

please find attached a simple approximation example.

Hi Teja,  I am new to Rapidminer, however, this can easily be done in Altair Monarch Dataprep studio software, the join table can be exported to a CSV file, the CSV file can be utilized by Rapidminer.
