Hi Atul

With 227/450 marks in pcb, your % is 50.4 %

So, you are eligible for neet .

This is because ,
To be eligible one need to pass class 12th board examination with at least a minimum of 50% marks taken together in PCB in your class 12th board examination if belongs to general category ; while it's only 40% aggregate in pcb for obc, sc and st categories . One should have also passed English in your 12th examination to be eligible
