@chittineni Brahmananda Rao Sir
In case you apply for two lots, you will get one lot plus some shares on proportional basis (not the full second lot). Some one applying for three lots will get more than you.
This is assuming, overall retail application will be less than 42 lacs. If total applications cross 42 lacs ( very unlikely) than all will get only one lot irrespective of there application size in retail.
My advise is to apply as much as possible, if you are applying retail.
Should you have more funds, depending upon subscription on last date, you may go for SHNI/ BHNI.
