Dear pulsar,
Don't regret for not knowing all the figures on your tip. It is impossible. We cannot go about memorising all byheart. Even as a HR Manager in Chennai, I don't know many of these figures so always I have a ready reckoner book (latest edition) with me for reference.
Many managers ask these just to pull off the interview time and for the sake of questioning the candidate. Many amendments in PF/ESI/P-tax etc are happening and sometimes we may not know that. So we have to cross check with updates and for that matter one cannot be scolded or humiliated. No one is perfect...!!
Incase of doubts, you can always ask the citeHR friends here or search the Net.
In the absence of pay components, the consolidated Gross itself is considered as Basic. Unless otherewise mentioned in the structure, you don't have DA/HRA/Cony?others.
So Min wages means Basic or (Basic+DA).
Keep going dear.
Regards,
Chandru
Manager - HR, Chennai
