RE: Monday's thinker...

I thought i’d start a thread on something that might exercise your mind, may help wake ppl who are bored at work or college…

OK, here goes…

**Imagine a bookshelf with 6 books on it numbered 1-6 from left to right. You need to re-arrange the order of the books on the shelf so that adjacent book numbers differ by at least 3 (i.e book 1 can only stand next to book 4) and the leftmost book number is as small as you can make possible (this is not necessarily book number 1).

**Good luck, and if you think you know the answer, then let me know and I will announce the person with the correct answer…so go on get ur thinking caps on…

Re: Monday's thinker...

4-1-5-2-6-3

Re: Monday's thinker...

and 6-3-5-2-4-1

Re: Monday's thinker...

very close....

Re: Monday's thinker...

seeing as ur the only one present....the answer is:

362514

Re: Monday's thinker...

Anyway another thinker for u clever cloggs out there:
**
I visited London Zoo yesterday, and they had a special exhibition of snakes and lizards in the reptile house. As I went round, I counted a total of 27 heads and 70 feet. I was counting only snakes, lizards and people and I know that there were exactly twice as many lizards as people. Can you tell me, how many snakes did I count?

Re: Monday’s thinker…

:slight_smile: wrong

1-4-2-5-3-6

PS: just saw THAT bit.. :grumpy:

Re: Monday's thinker...

so that adjacent book numbers differ by at least 3...

Re: Monday's thinker...

ooops I made a poo pooo :(

My tubelight moment... sighz.. I need a break

Re: Monday's thinker...

yes, i think u do....

try out the 2nd one, see if u can get that....

Re: Monday's thinker...

assuming no abnormalities i.e. all lizards had four feet, all humans two and all snakes none.

14 lizards, 6 snakes, 7 people

Re: Monday’s thinker…

this is the basic linear algebra question…

let number of snakes be S, number of lizards be L and number of people be P

we have 3 unknowns and hence we require 3 equations to solve the problem…

total of 27 heads gives equation 1: S + L + P = 27
total of 70 legs gives equation 2: 4L + 2P = 70
assuming all lizards have 4 legs and all people have 2
twice as many lizards as people gives equation 3: L = 2P

from equation 3, we can take the value of 2P = L and substitute it in equation 2, we get: 5L = 70 (i.e. L = 14)
and we know that P is half of L, hence P = 7
putting values of L and P in equation 1 we get,
S + 14 + 7 = 27 → S = 27 - 14 - 7 = 6

Re: Monday's thinker...

The answer to the 2nd thinker was that I saw 6 snakes ( along with 14 Lizards and 7 people!). Well done to all those who got it right....

Re: Monday's thinker...

Third thinker of the week is as below:

Study this paragraph and all things in it. What is wrong with it? Actually, nothing in it is wrong, but you must admit that it is most unusual. Don't just zip through it quickly, but study it scrupulously. With luck you should spot what is so particular about it and all words found in it. Can you say what it is? Tax your brains and try again. Don't miss a word or a symbol. It isn't all that difficult!

If you think you can work out this little brain-scratcher, drop me a PM and I'll tell you if you got it right and, as always, the answer will be posted here as soon as someone gets it right.

Good luck!

Re: Monday’s thinker…

^ old one :yawn:
there is no letter e in this paragraph, although it is the most used alphabet…

Re: Monday's thinker...

clever cloggs! You're absolutely correct....
