IQ: Psychologist Test for Mathematical Insight

The coin one ("Price" I mean) should be 9, rather than 8.

The one with the ostriches and giraffes "tricked me" in that I actually attempted to make an equation for it (and then I was like... oh, wait, DERP!).

The one with the sequence of numbers I just got the wrong answer for, I guessed 60.

I thought the one with the 10 weights in 10 bags was the most interesting.

For the frog one, I assumed that it would take 1 day to get out of a well that was 2 feet deep; based on this assumption, would 31 be the correct answer?

I did manage to make a mathematical formula for the sequence question where 60 turns out to be the next number, however I'll still count that as incorrect.** I would like to understand that question better though, and how I could have been able to find the answer from looking at the sequence. I think I was on the right track though, because it's almost like I heard your voice coming out of the page reading out the sequence in a sort of "come onnnn, what comes neeeext? " sort of tone, however I had already veered too far off track by that point.

Otherwise, I got the other 10 right, it took me no more than 10 minutes* to go through them all.

* actually, due to the 10 weights question, I may have gone slightly over the 10 minute mark

** actually, I just checked, and the formula I came up with doesn't even work, so yeahh

Hmmm, I will definitely grant a prize if someone finds an error

That would be delicious!

Question 12. Why? A porn broker charges interest, so the answer must be wrong, because the question must be incomplete, causing question 12 to be wrong.
The 50c difference the man with the two pound note porn'd is not interest payed.
