Check Your General Intelligence
To test your general I Q, answer the five questions below.
Try to answer each spontaneously - and then check the answers below.
So here we go ...
[1] You are participating in a race. You overtake the second person. What position are you then in?
[2] What's your position if you overtake the last position?
[3] Take 1000 and add 40to it. Now add another 1000. Now add 30.Add another 1000. Now add 20. Now add another 1000. Now add 10. What is the total?
[4] Mary's father has five daughters - Nana, Nene, Nini, Nono and (what's the name of the fifth daughter)?
[5] A mute person goes into a shop and wants to buy a toothbrush. By Imitating the action of brushing his teeth, he successfully indicates to the shopkeeper what he wants and the purchase is done. Next a blind person comes into the shop - he wants a pair of sunglasses. How does he indicate this to the shopkeeper?
Answers to questions ...
- Not the first position - if you overtake the second person, you are the new second placer.
- Not the second last person - there's no position from which to overtake the last position!
- The answer is not 5000 - it's 4100. Check with a calculator.
- Not Nunu. Mary!
- He asks - he's not mute!

That 3rd one was messing with whats left of my mind, till I figured it out.
ReplyDeleteLoved that last one.
I'd take issue with your answer to Q. 2. Since you didn't specify the race being run, I'd have to say that it is entirely possible to pass the person in last position if you are winning and you lap them.
ReplyDeleteAlso why would anyone think the answer to Q.3 was 5000?
Got anything harder? (Oh, innuendo. Fnaar.)
Seasons greetings.
hey Ive
ReplyDeletethere will be situations where this doesn't fit - of course you are right - i was thinking of the more usual or general case.
for some reason a lot of my friends doing No. 3 come up with the answer 5000 - no idea why - something (psychological) about the way the problem is put that distorts the result
here's something harder:
The goal cell holds three prisoners. In the morning two are to die. The jailer is to decide which one is to live.
In view of the prisoners, our custodian takes five small squares of paper and on three he places a cross and on two a circle. He then tells the prisoners he will randomly select three of the pieces of paper and discard the remaining two. And that he will place one square to each of the prisoners’ foreheads. Each will be able to see what is on the others’ foreheads, but not his own. In fact the jailer secretly contrives to select only the three squares with crosses on them.
So each prisoner now has a square with a cross on his forehead. But while each sees a cross on the forehead of each of the other prisoners, he himself could in fact have a circle or a square attached to his own.
The jailer tells the prisoners that the one to tell what is on his forehead with the right reasoning will be freed. A guess, even if right, with the wrong logic will result in death.
One prisoner took less than five minutes to determine the answer. And gain his freedom.
What was his argument?
hey greg
