NTPC Question Paper For Human Resources

I have applied for National Thermal Power Corporation (NTPC) Human Resources (HR) executive examination ? I have prepared for it but for my confidence I want to solve some Question Paper . Please provide me a book that publish this NTPC Question Paper for Human Resources ……

Sir I am looking for the NTPC question for Human Resources so can you please provide me the same
