How many marks and questions do i need to do correctly to pass the ZCO?

How many marks and questions do i need to do correctly to pass the ZCO and be selected for INOI successfully.

Depends on the difficulty of the questions asked.
Once the tasks were quite difficult so the cutoff was 1 (any non-zero score).

Male students:

Class 12: Everyone with a total score of >= 27/200 will qualify for INOI
Class 11: >= 22/200
Class 10: >= 20/200
Class 9: >= 17/200
Class 8: >= 16/200
Class 7 and below: >= 16/200

Female students:

Class 12: Everyone with a total score of >= 21/200 will qualify for INOI
Class 11: >= 16/200
Class 10: >= 13/200
Class 9: >= 12/200
Class 8: >= 11/200
Class 7 and below: >= 11/200

Thanks for the table of requirements, but how many points do different tasks give?

its written in the question with a keyword like

subtask 1 : 20 points or x points
