I did the test at http://simple-iq.com/ and scored 142 points in around 7.5 minutes. Knowing the answers the second time round, I raced through the test in less than 1.5 minutes and scored 146. I then did the test again, in 1.5 mintues, correcting the one i knew I had gotten wrong and scored 149. Not much of a jump for the speed or accuracy, which made me wonder if I'd gotten some more of the questions wrong. I wrote them down and thought about them, then (failing to find any answers on Google) thought I'd ask some of the more intelligent and logical minds I know, what their opinions of the answers were.. So here it is. I also listed my age as 10, and raced through the test (getting one wrong) and scored 182.. So I'm also wondering if there is an age at which intelligence as measurable by a test such as this, plateaus.. Note that I'm colouring the words the same as the background to make them near invisible, should you wish to take the test and not risk this spoiling it. To reveal the Q & A, select the area below: 1)the word vile can be written using four of the letters from the word violates True. Violates does contain V, I, L and E 2) if you write down all the numbers from 1 to 25, every two numbers following one another will add up to an odd number True. in any sequence of numbers where the difference is 1, two successive numbers are an odd and an even, and the sum of odd+even is always odd 3) 13 minutes after 5 oclock is exactly 47 minutes before 6 oclock True. Because there are 60 minutes in an hour, any pair of numbers adding up to 60 can be used to express a time being after 5, and before 6. ie.e 5:45 = quarter to 6 4) the word amity is written by using the first letters of "a mouse in the yard" True. Read the first letters downwards: A Mouse In The Yard 5) if you turn a left hand glove inside out it will become a right hand glove True. My opinion was divided on this one. Inside out or not, a left hand glove (IMHO "glove intended for the left hand") is still a left hand glove, just like a football is still a football even if it has no air in it. However, I felt the sentiment of the question was whether a left hand glove would fit a right hand, if turned inside out. Note also that some gloves, like surgical ones fit either hand anyway. 4) Peter has $15 and he can buy a $30 bike if he borrows $6 from john and $8 from george False. Given that he would have only $29 in this case, he should wait for the sale or try a bit of bartering 5) the big arow points to the right on a clock that's turned upside down and showing quarter to one True. Quarter to one on an upside down clock looks like quarter past seven so yep.. the minute hand is pointing to the right 6) in the following sentence, if you were to exchange the string wind for the string will, the sentence would make sense: They asked him if he would windingly change his wind True. They asked him if he would willingly change his will, makes sense to me. Bit of a programmers question this one, because I dont see ordinary people referring to sequences of characters as "strings" or being familiar with the semantic of Find/Replace affecting parts of words as well as whole ones 7) If peter looks at a mirror and touches his left ear, his mirror image will touch its right ear True. I think most people who have used a mirror know that mirrors reverse the image in one plane (as defined by the positioning of the eyes) 8) From the sentence "she dents it" without changing the order of the letters, we can make the words "shed ent sit" True. Moving the the first space to the right by one ,and the second space left by one, realises the second set of words 9) Using exactly three colours you can paint the sides of a cube so that sides of the same colour will never touch True. Having 6 sides, and considering them in pairs on opposite sides of the cube, it would take 3 colours to paint the opposite sides. Look at your monitor or other square object near by. Touch the left and right side, now touch the top and bottom, then the front and back. You always touched sides that were not connected 10) john weighs 150 pounds, anton weighs 130 pounds, peter weighs 200 pounds, two of them can stand together on a weighing machine and will weigh exactly 350 pounds True. If john and peter at 150 + 200 pounds stand together on the machine, it will read 350 pounds 11) The third vowel in this sentence is O True. The first is E and the second is I, the third is the O in vOwel 12) Seven chickens and two cats have twenty two legs among hem True. The seven chickens contribute 14 legs. The two cats contribute 8 legs. 14 + 8 = 22 13) if I have a quarter, a dime (10 cents) and 5 cents and i spent 33 cents, i will have fifty two cents False. A quarter, dime and 5 added are 40 cents. Spending 33 should leave you with 7 cents, not 52. Thankfully, even non americans can answer this question (The first time I took a test like this, I didnt know how many cents were in a dime) 14) there are four letters between K and P in the alphabet True. In my understanding of the word "between" (i.e. the Oracle database SQL sense of the word), it is non inclusive:k L M N O p 15)If the word ERA is written below the word ANT and the word RAT is written below ERA, then the word art will form diagonally True. ANT ERA RAT 16) 0.55 hours added to half an hour is exactly 85 minutes False. Even if youre not sure how many minute 0.55 of an hour is(33 minutes), 0.55 about 0.5 which is a half, which is about 30 minutes, added to 30 minutes, is about 60 minutes.. Some fair way off 85 minutes. Just remmeber that there arent 100 minutes in an hour, and 0.55 is not 55 minutes 17) five gloves and 3 shoes will most often hold 35 fingers False. On my world, five gloves hold 20 fingers, and 5 thumbs. Shoes dont generally hold any fingers so they dont contribute. I've looked and looked for the trick in this question, but I cant find it.. 18) a house in the form of a donut has 3 doors on the the outside wall and 3 doors on the inside wall. it is possible to pass through all doors only once and end up where you started False. With this house youre either inside it, in the courtyard, or in the street. You cannot arrange the words "courtyard", "inside" and "street" such that they form the pattern: __, inside, __, inside, __, inside, __ where the 6th word is the same as the first. (Starting inside the house doesnt count because you'll end up locked out of it after an odd number of doors.) street, inside, street, inside, courtyard, inside, courtyard street, inside, courtyard, inside, street, inside, courtyard 19) the words ski, executive and prime and can be combined with the words jump, director and minister True. Ski-jump, executive-director, prime-minister 20) If tuesday is the 2nd day of the month, then the first sunday would be the sixth of the month False. Sunday is the fifth day after tuesday making it the 7th of the month, The 6th is a saturday 21) Two of the following numbers can add up to the number 17: 11,3,2,14,15 True. Again, i wonderd if this was a trick question because 4 of the numbers add up to 17. 15+2 and also 14+3. The question doesnt really give much of a hint about pairing, so i read it literaly, yep.. I can pick two of those numbers such that they will sum to 17. Whether I can do it once or twice is irrelevant. 22) John will be 3 blocks from his starting point if he walks 2 blocks north, 3 blocks east and 2 blocks south True. The north and south cancel out, leaving him where he started (longitudinally). Unless he is near the north pole, in which case things get really weird. He could technically end up more than 3 blocks from his starting point if he walks north towards the pole, then turns east and walks in a 360 circle around the pole (radius 3blocks/2PI), then walks south, he will finish up where he started. Or some distance other than 3 blocks, if he started walking south 180 degrees opposite where he walked north (describing a circle of radius 3blocks/PI). Specifying a city on the equator would have been a wise move for this question. 23) There are words that start with b that are the opposites of: ugly, good, exciting, worst True. Beautiful, Bad, Boring, Best 24) The word "revolver" reads exectly the same back to front False. the OL in the middle means that this is not a palindrome 25) The letters in "flops" are in alphabetical order True. FghijkLmnOPqrS 26) The numbers 649302 are read backwards as 203649 False. The 649 doesnt reverse. 649302 backwards is 203946, which, by some amazing coincidence is the pin number for my cash card, and to pick an easy one to remember for my online banking, I used the same pin but backwards (and that's why this question was a doddle). I think i should go change my pins now. 27) The daughter of Peter's grandfather can be the sister of peter's son False. Well, no, actually, it could be true, but given that the daughter of peter's grandfather is more likely to be Peter's mother or aunt, Peter would have to have a child with his grandmother for the child to be the sister of the generation older than Peter and I'd like to think that things like that dont actually happen, so I said false to this. 28) Without breaking or twisting any match sticks you can write the word FIT with exactly 5 sticks False. The F would require 3, the I would require 1 and the T would require 2, making 6 sticks. I got this wrong when I first played. Oops. 29) This sentence has exactly thirty eight letters False. It has forty letters. Actually all sentences in English only use 26 letters (simplifying the soupçon of words nicked from other languages), but the sentence didnt say the word "distinct" so in the Oracle database sense of the word.. 30) A square with 10 inch sides can always fit within a circle of raduis 10 inches with the points of the square lying on the circle False. From pythagoras we know that a square of side 10 would have a diagonal of length ROOT(200). To diagonally span a circle of radius 10, diameter 20, this would have to have a length of 20, or ROOT(400). A square of sides 10 fits within a circle of radius 10, but does not touch in any place 31) A hexagon can be separated into 6 identical triangles by two lines False. I cut a pizza up in my mind, and really couldnt get 6 slices out of 2 straight cuts 32) The number 62 is the next logical number in the series 2, 6, 14, 30 True. The difference in each number is 2^N+1 where N is the numerical index of the term. Basically the difference goes 4, 8, 16, 32.. And 30+32 = 62 33) John is taller than Peter and Tom is shorter than John. That means Peter is the tallest False. Peter cannot be the tallest because the first predicate is that john is taller than peter. 34) The sum of all odd numbers between zero and twelve is also an odd number False. There are six odd numbers between 0 and 12. Because six is an even number, six odd numbers added will always be an even number. The only way to realise an odd number from a sum, is where the sum contains an odd number of odd numbers! 35) If six people form a group, and every one of them says hi to all the other members, that would mean the word hi would be said 36 times False. For the word Hi to be said 36 times, each person would also need to say Hi to themselves. As it stands, each person must greet five others. 6 people * 5 greetings is 30 greetings 36) Three identical circles can overlap so as to form exactly seven different zones True. I'm sure youve seen the primary, secondary and white colour diagram in computing. The red, green and blue circles overlap to give the secondary cyan, magenta and yellow, with white in the middle where all 3 overlap. I mentioned 7 colours Did anyone notice the deliberate mistake in the answers list? I would also be interested to know, if you logically approached any of the questions differently to me; how did you rationalise or solve the problem? What was your logical process? I'd like to know, partly to learn how others think, and partly to improve my own logical approach..
