Shivansh Gupta commented Dec 20, 2017 Like reply Follow Share Do they give new keys when they make these many mistakes ?? Tuhin Dutta commented Dec 20, 2017 i edited by Tuhin Dutta Dec 21, 2017 Like reply Follow Share In their last exam, they cancelled all questions having wrong keys. They marked upon 231 instead of 240 since 3 of the questions had wrong keys. Qno 23 of set A has all wrong options. Ans would be d) but printing mistake is there so it should also be considered as wrong. right? So till now, we can report for all the below questions: 48, 70, 27, 18, 43, 8, 23 right??

They cannot even do their recruitment process properly. Its not all rainbows and roses once u get into ISRO as well afaik. Tuhin Dutta commented Dec 21, 2017 i edited by Tuhin Dutta Dec 21, 2017 Like reply Follow Share @sid1221, Qno 76 of set-A in this question they have explicitly mentioned external 1 in option b) which was not mentioned in gate question https://gateoverflow.in/1487/gate1999-2-9 . So option b) becomes more obvious than option c) because in option c) external 0 & 1 are needed. I think ISRO key is correct. option b) is more appropriate than c). Sumaiya23 commented Dec 21, 2017 Like reply Follow Share Set A, Q 9: No, the answer is correct (option B - surjective but not injective).

Abbas2131 commented Dec 26, 2017 Like reply Follow Share @anup Patel Actually it is not reflexive as 0D0 is undefined. Abbas2131 commented Dec 26, 2017 Like reply Follow Share Qus no. 15, answer should be C it is in BCNF too :( Anup patel commented Dec 26, 2017 Like reply Follow Share Abbas2131 then which option is correct Not Reflexive Antisymmetric Transitive Abbas2131 commented Dec 26, 2017 Like reply Follow Share Yes, The relation is : not reflexive, Antisymmetric, Transitive. I don't understand how they have given Not antisymmetric, because the definition states that If aRb and bRa then a=b, which i guess should be true for this relation Please log in or register to add a comment.
