Can you solve this ? Zagreb UNI humanities entrance exam

[Minesweeper]

The questions are solvable but I don't understand, they have this instead of history, sociology, etc?

[Duke]

Well, I didn't understand all of the questions too...
For example, 2009200920092009...etc, the number of odd numbers followed by an even number is 2009, right?
Or is it 20092009... etc, followed by 2.
Or maybe 200920092009...etc, followed by 2.

Or maybe, it's the sum of all of these which would make 2009+2009+2009/2+2009/3+...

It's confusing.

its 9*2008, because in last sequence there is no even number

yep, of course if you consider that one number = one digit, because 2009 is an odd number too, so is 20092009, 200920092009 and so on.
The question is weird!

its not weird, you need to add every 9 that has 2 after it, its easiest question of the 10

there are 2009 9 in total, but last one doesn't have 2 after it so its 9 times 2008

Ok, the question is not weird but imprecise, it should have been about the sum of odd digits, not the sum of odd numbers. I would have spent all my time trying to calculate something that can't be calculated by hand.

problem is google translate, but your logic still fails, if you thought on literary on number and not a digit, then whole sequence is 1 odd number, and that doesn't make sense, right?

I haven't used google translate, I translated it myself. Sorry for imprecision.
Will write down explanation for two questions you asked about, just wait.

@Minesweeper: yes, they have this test of ''intelecltual capabilities'' instead of history, sociology etc knowlege
Although you have to write specific subjects on matura-for example psychology for psychology course , etc.

Maybe some of your questions are not translated good, i had some trouble dicipering some of them, but i am interested how did you get 32% on second, and not 30,5%, and in 5th question that answer is impossible, 138km/h to travel 144km, in 100 minutes??? that speed would be closer for 60 mins travel time, or am i wrong here

Question no. 5:
I FORGOT TO WRITE CARS TRAVELS 3 MNS TO THE EAST, f--k. Sorry

v1/speed - 90 km/h
t1/time - 3 mns
t2 - 100 mns
s/speed - 234.5 km/h
.....
s1=v1xt1=90 km/h.......x=0.05h=4.5 km....means he drove 4.5 km from point A to point B.
s2=234.5-4.5=230 km......v2=s2/t2=230km/100 mns=230km/100x1/60h = 138 km/h.

Of course you couldn't solve it when I forgot to write down entire thing. LOL

well that makes whole lot difference, i took into account while reading it that it drove 1 hour for 90km before turning, which then left me 144km taken in 100 minutes

also this one is bit confusing as written
From 30 high school graduates, 8 applied for architecture, 20 for humanities, and 30 for medicine. How much candidates did apply for at least one course ? And the most that applied one course ?


because as written, all 30 took at least 1 course, i got the minimum right

Question no.2:

P/probability= 39/ 24 + 56 + 39....P=39/119= 0.327=32.77 %
