P/E and P/B

hi Mahesh ji, I have query on P/E and P/B. As per my understanding for getting high returns we should select stock with less P/E ratio. Is there any range in the P/E ratio (Per sector). Whether P/E ratio range vary from sector to sector? Can you tell me the sector wise range of P/E ratio which is considered to be less. What range of P/E ratio is less to get high returns for sectors Banking, Pharma, Oil and gas, Automobiles, Media, Infra, Capital goods. Thanks & Regards M Rajkumar. 
1.P/E means price/earnings ratio ,this is an old criteria to choose stock for investment but I believe on net revenue per share concept instead of P/E.

3. P/B means price/book value ratio for getting a value stock , i prefer base price instead of book value.
