Hello Manoj.

From the previous years' records, it can be predicted that for 70 marks you can get a rank close to 10K. Since you got 80 marks you are more likely to get rank less than 10K. So, you'll be able to apply to all JNTUs. And you might also be placed into some JNTU as your rank will be less than 10K.

All the best.
