I think the tests are harder than a normal IQ test, so the average persons results should be similar to a German Shepherds.

here's a classic one:

A man stood before an open casket at a funeral service and said " Brothers and Sisters ,I have none. But this man's Father is my Father's son.

who's in the casket?

There are certain alien beings in a room who are all identical. Each has exactly one hand with a certain number of fingers. (Of course, that number of fingers per hand is the same for all of the aliens, since they are identical.) There is more than one of those aliens in that room and each one has more than one finger on his hand. Other than those aliens, there is nothing else in the room. The total number of fingers in that room is greater than 200 and less than 300. If I told you the exact number of fingers in that room then you would know exactly how many fingers each one of the aliens has on his hand. How many aliens are in the room?

10x=9y
10x-9y=0
also
5(x+y)-50 = 10x so
5x+5y-50=10x
5y-50=5x
x=y-10
x-y+10=0
10x-10y+100=0

subtract the bolds
( 10x-9y=0 ) - ( 10x-10y+100=0 )
-y+100=0
y=100

10x=9y=9(100)=900
x=90

5x+5y=5(90)+5(100)=950

subtract the rate deficit
950-(10x5)=900
whew!
