Found PEA completely different than all the previous years papers so was somewhat taken aback. :(
What about you?
And did you find this PEA easier or tougher than past years? I'm asking to get an idea about the cutoffs.
I just hope the cutoff for both goes low.
Those math questions weren't like the past papers there weren't many direct questions and those 2 monkey questions were very frustrating. Not many eco graduates are able to clear the PEA so I won't expect the cutoff of PEB to go above 65 but you never know with the amount of talent this country breeds 😑
Engineer here. Math wasn't so tough personally but I got absolutely destroyed and mauled in economics. I wasn't expecting Macro to be very theoretical. I too hope the economics cutoff is 60ish or less, I may get in then.
About the monkey question, it can be solved by using binomial distribution and summing probabilities which form a geometric series. Alternatively you can put values of k, and look for the answer that makes sense. Couple of them were absurd and could be ruled out at sight.
Probability it reaches k= Probability it reaches in 1jump, plus probability it reaches in two jumps and so on. Individually these are going to be bionomial.
P is fixed, it can take any value between half and one, but we begin our analysis by fixing P. If p keeps varying jump to jump as you hypothesised it would be an interesting question but a near impossible solution for me.
