automated content generation

The project is for generating the content of aptitude questions in an automated way. there are different types of aptitude questions, like questions on ages, percentage, permutation and combination, interest, probability etc. for each type of question, we have a single format available with us. Suppose, the formats are what is {v1}% of {v2}? Find {v1}!/{v2}! the format of questions are stored in an excel sheet and the system does the following functions. 1. firstly a single formats needs to be taken as input from the spreadsheet. 2. the variables need to be changed with random values. the ranges of these values are specified in the spread sheet. like v1 can range from 20-30, v2 ranges from 30-70. 3. now the system takes in the formula as input and puts the values into it to get the answer 4. the answer is used to calculate 3 incorrect answers 5. the question along with correct and incorrect answers is stored in a new excel sheet. the same process is repeated to read all question formats and get multiple questions. the input and output of the system can be understood better by seeing the attached files.
