I am OBC candidate in cap 1 alloted type is LOBC but in cap2 alloted type is LOPEN then which category fees pay

Dear student, 

In the first round of CAP, you were allotted a seat in the LOBC category, which means that you were admitted under the OBC reservation. In the second round, you were allotted a seat in the LOPEN category, which means that you were admitted under the open category.

In this case, you will have to pay the fees according to the LOPEN category, which is the same as the general category fees. This is because the OBC reservation is only applicable to the first round of CAP. In the subsequent rounds, all seats are filled on a merit basis. So, even though you are an OBC candidate, you will have to pay the same fees as a general category candidate for the seat that you were allotted in the second round of CAP.
