oh really, my grammer is that bad, oh my Darwin! I didn't really know? Oh well, I mean emerging from an Ape, what more can you expect? Well any way, this test is not about grammer, but to see if you can work out simple logic.
I will provide the correct answer tomorrow and give a precise reason for why it is a correct answer and whos brains are dearranged.
I actually have a phenomenal logical brain so much so that in a phsychometric test the examiner told me I was the only person who had ever scored 20/20 in the logic section of the assesment.
Which brings me to why your problem is badly presented. if its badly presented it is either a trick question and NOT a test of logic but a test of INTERPRETATION. if the question has been badly worded then we have a grammatical error.
Lets just see why this puzzle is wrong..
To explain lets name the subjects A and B...
The first thing you have to assume is that the subjects are male. The first description says 'people' but later references only mention he.
The next thing we have to decide is whether A or B is the subject who visits the toilet. Lets say A is the one who stays put and B is the one who visits the toilet.
Two people (A and B) were to meet in a room full of clutter, both sit across a table to discuss a subject, at first one (A) notices a Fiver lying among the clutter, then the other (B) notices the same fiver, but neither tells the other that they saw a fiver which appears to have been forgotten by someone, they both knew that the fiver wasn't theirs, later on one of them(A) excuses the other(B) to go to the loo, when he (B) comes back,
Now this is where the logic and the question fails..
The next 'he' could refer to either A or B and both would have a different outcome.
If the next 'he' refers to A then . .
he(A) notices that the fiver is gone! Among the clutter there are some mice droppings as well.
In this scenario A has stayed put and B has been to the Loo and therefore if A notices the fiver has gone it could be because either HE himself has taken it in which case its misleading to say he notices the fiver has gone since he would already know he had taken it. So the conclusion is the mice took it .
However if the next 'he' refers to B then...
he(B) notices that the fiver is gone! Among the clutter there are some mice droppings as well.
In that case the answer again is not certain. If B comes back from the loo and notices the fiver is gone then it could equally have been taken by A or eaten by mice.
BTW you spelt deranged wrong . .
