How was your paper? I think the paper was hard and there were way too many problems on econometrics! How much do you all the cut off is going to be?

[throwaway]

I thought the paper was hard too.

Also, there was one incorrect question I believe, the Baye's theorem one (had wrong answer options).

Cut off I believe should be 41-42ish.

You r right. All the options were  incorrect. Cut off will be exactly 40 this time as well.

[onionknight]

I think the answer is there in the options. Isn't it 1/3

[dashabhisek]

yes,it is 1/3

Really? Wasn't it coming out to be 999/1017? I must have done it wrong then.

Even I got 999/1017. How did u guys do it ??

Onionknight, how was ur exam ?? How did u find it compared to last years ??

[onionknight]

The question says 0.1 percent population of the city has the disease. I think you treated this as 0.1 fraction, same as I was doing earlier.

[onionknight]

It was pretty hard, sort of like last year.

[throwaway]

Yep you're right. Fortunately I didn't attempt it, so no negative marking.

Similar question - There is a deadly disease which affects 1 in 100 people. A lab test can correctly identify positive cases
99% of the time and correctly identify negative cases 95% of the time. A randomly selected person
tests positive. What’s the probability that they have the disease

Ans.  (.99)(.01)/(.99)(.01)+(.05)(.99)

[tanudas]

It was 1/3. Even I wasn't converting the 0.1% into a fraction.
How many did you attempt in all ?

[bhupesh.bhuppy]

Someone please post the solution.. as given by someone like amit sir here of the exam

[throwaway]

Wait for a couple of days. DU has been uploading answer keys of Postgraduate exams on their website, so maybe they'll do it for DSE as well.

[priyesh]

[deepti]

Yes it was cmg out to be 1/3

In our room, invigilator insisted writing OMR answers with pen, and not with pencil. All of us said it's written that pencil is to be used. But he said univrsity instructed them. So we had to write with pen. Will that be a problem? Anyone else faced this?

[yuganshi]

no we were instructed to write in pencil only. My centre was at FMS.
Was your centre at SGTB khalsa?

[onionknight]

I was at faculty of social sciences, DU. We were asked to use a ball pen.
