Central Board Of Secondary Education [CBSE] — class 10 board exams question paper mistake

The question states that the ph of the salt used to make tasty and crispy pakoras is 14. This therefore was a wrong question as a substance with ph 14 is not edible.
This was question number 10 in set 2 of the science question paper.
So, we request you to take the required action as it was not an answerable question. It would be unfair if we loose our marks for the same.
