test your intelligence 3

time passes fast when u r slacking at home, but now that i'm working, i realised time passes faster when u work.

anyway, it's tuesday again! time to test ur intelligence, but sad to say no one has yet to solve for last week problem.

This week's problem shall be slightly easier:

A high school has this ritual on the last day of school: The students go into the hall and stand by their closed lockers.

At the first blow of a whistle, the students open every locker. At the second whistle, the students close every second locker (lockers 2, 4, 6, etc., are slammed shut). At the third whistle, the students toggle every third locker. To "toggle" means to close it if it's open, and to open it if it's closed. They toggle 3, 6, 9, etc.

At whistle four, they toggle every fourth locker. At whistle five, they toggle every fifth locker, and so on.

Let's make things easy and say it's a small school with only 100 lockers. At the one hundredth whistle, the student standing next to locker 100 toggles his locker.

How many and which are the lockers are then open?

i personally feel this is a gd and challenging question...

You have 12 coins. One of them is "defective", meaning that it weighs differently from the others. How do you tell, using a balance, which coin is defective, and whether it is lighter or heavier than the others, in 3 weighings?

have i asked this before?

comments/suggestions

recently, i have been thinking whether i should organise something for my coming birthday, i.e maybe treating some gd friends to a meal.

definitely not some party thing like the one yuneng organise la... of course, just something simple..

problem is: i don't whether i should do it. anyway, i don't think anyone will expect me to do anything also rite?

hence, if u happen to be reading this, i would really like to know whether you think i should 'celebrate' it.

below are some reasons which i think i shouldn't do anything:

• since, if i do anything will definitely be on 2nd july, so it's the next day after chung hang's celebrate his, a bit 'bo' rite? like too consecutive liaoz
• if i invite some, since i no $$, will those whom i omitted feel bu4 shuang3?
• maybe there's no one who really care about whether i do something or not

anyway, just like to do a initial response check, so kindly feedback

wat i do...

these days, i realise i have a frequent and common question posted to me by the people i met:

"u not working? stay at home, do wat?"

sometimes, i spend my time thinking of answers to questions which seems forever to solve (see previous post "test your intelligence")

today, while surfing the net, looking for something to keep me entertained, i came across this website:

http://www.mitsubishicars.com/06eclipse/eclipse_micro.html

i suggest that those who r like me, with nothing better to do, to check the above website. try the "thrill-ride challenge"

the driver with the fastest timing for that particular race will win an ipod-mini.

i thought: ok, since i'm quite gd at some racing game, e.g. initial d in ps2 and NFSU2 in pc, maybe i should give it a try..

haha.. i spend at least an hour on the not-so-excellent graphics racing game, only to finally manage a loser timing below 4 mins.

the thing is.. i m no where close to the top racers. the fastest currently recorded is an unbelievable 30.9 sec. i look like a complete loser with my results..

i have came to the conclusion that these other racers are either superhumans with super reflexes or they simply hack into the programme to attain such results.

anyway,

i challenge anyone to try out the "thrill-ride challenge". who knows, u may end up with an additional ipod...

test your intelligence

stop slacking and let your brain do some work... some say this is a pri. 5 mathematics problem.


5 pirates on an island have 100 gold coins to split among themselves. They divide the loot as follows: The senior pirate proposes a division and everyone votes on it. Provided at least half the pirates vote for the proposal, they split the coins that way. If not, they kill the senior pirate and start over. The next most senior (surviving) pirate then proposes his own division plan, and they vote by the same rules and either divide the loot or kill the senior pirate, as the case may be. The process continues until one plan is accepted.

Suppose you are the most senior pirate. What division do you propose? (The pirates are all extremely logical and greedy, and all want to live.)

answer will be disclosed a week later should no one manages to get it correctly.

Top 10

Listed below is my personal top 10 unique experiences from my 3 days K.L. trip (not in any particular order)

1. i got served claypot chicken rice in a plate, simply because they run out of claypots

2. it seems that there is limited bowling balls in their bowling alleys

3. their shopping centres/malls are so big, i think u would have walk at least 4 km visiting every shops

4. the first floor in singapore is known as ground floor in k.l., basement is known as lower ground

5. they have excellent drivers. even their 5 tonners/landrovers travel at 100km/h

6. the 'pirates' seems to be well-prepared for any raids. they have walkie-talkie to keep each other informed

7. the numerous tolls made travelling much more expensive

8. the price of movie tickets varies with different movies, the most expensive is still cheaper than singapore's

9a. travelling by cabs seems to be cheaper than travelling by their train system. just make sure they switched on their meter

9b. when travelling by cab, they charges 20 cents more when there are 3 passengers and 40 cents more when there are 4 passengers

10. the length of their train does not coincide with the length of their platforms

5 Books I Recommend

Title: Out
Author: Natsuo Kirino
What is it about: A japanese thriller on what happens when people are pushed to their limits. I would say it's quite different from the usual stories I read. A page-turner.



Title: The Rule of Four
Author: Ian Caldwell and Dustin Thomason
What is it about: There are readers whom say that this book is nothing compared to the widely proclaimed "The Da Vinci Code" by Dan Brown, but since I had yet to read the latter, I can't really make the neccessary comparison. However, I personally enjoy the plot of this book.



Title: Shopaholic Ties The Knot
Author: Sophie Kinsella
What is it about: This is probably for the female readers, some of you may think, but the story itself is outstanding. It really captures the reader's attention and while reading you can really feel you are part of the book. Though, there are many "Shopaholic" series by Sophie, I had yet have the opportunity to read the rest.



Title: The Time Traveller's Wife
Author: Audrey Niffengger
What is it about: This is the book that I will always have on my recommending list. The story integrates the love story between the two main characters, Henry and Clare with the scientific aspect of time-travelling. A truly touching and original love story on how love can survive the test of time. A must read!


Picture Not Available
Title: Inside Out
Author: Elise Title
What is it about: Probably the least heard book and author out of these 5 I recommended. However, this book had really proven how well a female author can write thrillers. This is the second book of the series, with main character Natalie Price. First book is "Killing Time". Heard the third book "Conviction" is also available now. Anyway, "Inside Out" has twists to its' story and plot that will caught you off your guard. Don't ever think you know who's the killer...
