Visvesvaraya Technological University — missing or wrong data in automobile 6th sem design of machine elements-ii question paper (dec 2017/ jan 2018)

Hi this is one the student of this universit from automobile branch.in a 6th semester paper of design of machine elements-ii (Dec 2017/ jan 2018) which took place on 8th jan 2018 there was a data missing in the question 3. B where the width and thickness were given as 90 mm but in actual they are 90 mm and 6 mm respectively. This led to the wrong solution of the same along with wastage of time. This is completely unfair for the students. As per the valuation process, grace marks should be awarded for the same. But when i received photocopy of the same subject i was awarded 4 out of 10 marks which is completely unfair. I am attaching a copy of the question paper along with a snap of the same question from one of the university prescribed books.
