Order: We find that for answering the question, a candidate will have to undergo detailed math analysis which is not expected in an objective test. Therefore, 115 is directed to be deleted. Perusal of 116 would reveal that it is dependent on Q.115.

Order: As a corollary, 116 also ought to be deleted. We set aside direction of HC of giving marks to all students who have attempted 115. We find that on account of confusing results, many students might not have attempted to answer.
