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…
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?
**
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
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.
