I guess these questions are designed to see how the person thinks. Either literally or out of the box type thinking.

[imchaser]

I guess if im the applicant, ill answer all the question with the same answer.

My answer to all questions would be:

"Ill Google it"

Here's another one

Four people need to cross a rickety rope bridge to get back to their camp at night. Unfortunately, they only have one flashlight and it only has enough light left for seventeen minutes. The bridge is too dangerous to cross without a flashlight, and it’s only strong enough to support two people at any given time. Each of the campers walks at a different speed. One can cross the bridge in 1 minute, another in 2 minutes, the third in 5 minutes, and the slow poke takes 10 minutes to cross. How do the campers make it across in 17 minutes?

[Guest mature]

is that difficult??

..only need 10min to across them all

now do tell us how you can make it in 10min

[Guest sblue]

Q4: How many times a day does a clock’s hands overlap?

Assuming that it starts at 0000, that's already 1 overlap. Every hour, it overlaps once, so 24hrs, 24 times, plus 1 so it's 25 times.

Q5: You have eight balls all of the same size, 7 of them weigh the same, and one of them weighs slightly more. How can you find the ball that is heavier by using a balance and only two weighings?

1st weighing: put 3 on each side. If the scale balances, the heavier ball must be among the 2 left out so 2nd weighing will tell the difference. If one side is heavier, take 2 of them from the same dish and weigh them against each other for the 2nd weighing. If it balances, it must be the one left out. If not, you'll have found the heavier ball.

Q6: You are shrunk to the height of a nickel and your mass is proportionally reduced so as to maintain your original density. You are then thrown into an empty glass blender. The blades will start moving in 60 seconds. What do you do?

The safest place would be to tie yourself to one of the blades and hope for the best.

You must write the question on a card which and give it to Eve who will take the card to Bob and return the answer to you.

Ask Eve to ask Bob for his number and call him yourself to give him your number?

If camper 1min can piggy back the rest, it'll only take 5mins to cross the bridge.

I was chatting online with AV and posted him one of the most

Suggestive Question above : Why are manhole round ?.

His answer : Because cock are cylindrical

Peter says : Why are manholes round ?

AV says : wahhhhhhhhhhhh

Peter says : man-hole NOT those holes in ass for Fxxking OK

AV says: suggestive

Peter says : haha, I knew it he will think that way, haha

AV says : for access to sewers, venting of gas

Peter says : haha, I think the question, why not square, oblong etc, Why design it round

AV says : can fit in anyway

Peter says : Good answer

AV says : easy to roll oso, no need to carry

Peter says : Easier to fxxk, haha

AV says : cos cock is cylindrical

Peter says : haha, Best answer ! haha

Peter says : This IQ question I saw in another book b4, The answer they offered is that it is for safety.

Square, Oblong shaped manhole shape. The cover can fall by the "diagonal" side and dropped into the manhole

AV says : orh

Peter says : But I think that your answer is very appropriate.

We humans, like cocks are also cylindrical shape

AV says : lol

Peter says : square and oblong manhole are not efficient

AV says : not shiok oso, less contact

Peter says: round shape manhole are most efficient in volume

AV says : lol

Peter says : haha, I think this question is design to catch gay man

Only gay man will think of cylindrical shape cock, haha

AV says : LOL

Peter says : and relate to man-hole problem, haha

AV says : gay btms esp

Peter says : haha, Go apply for a job with Google, haha, I go post your answer on BW, haha

AV says : haha

A=1min, B=2min, C=5min, D=10min

A & B cross first - 2 min

B returns to pass C&D the torch and A remain behind - 2min

B stays while C & D cross together and pass torch to A - 10min

A returns to fetch B - 1min

A & B then crosses together - 2 min

so total 17min

It may sound strange, but if u do rotate the clock's hand manually using a real clock, it only overlap 22 times. Cos when u did it, when the eleventh hours overlap, it actually shown 12. In another word 11 hour and 12 hour share the same overlapping. So 24 - 2 = 22.

If 11 & 12th hour share the same overlap, should'nt it be 23 times ?

Try this people.

Alson saw a pair of shoes which costs him $97. He borrowed $50 from Bernard and $50 from Chris.

Upon purchasing the pair of shoes, he decided to return both Bernard and Chris a dollar each, which leaves him with a dollar left.

So now, let's trackback together:

When Alson returns Bernard the dollar, he still owes Bernard $49, which applies the same to Chris as well.

Therefore, Alson owes both of them $98 in total. In addition, he still have a dollar left on his hand,

which sums up to $99.

The question comes: Where did the last dollar go?

Have a great day ahead,

XOXO.

Look at it this way.

If he sells his $97 pair of shoes to David for $97, which means he didn't earn anything.

He has $97, and $1 in his hand = $98.

He pays Chris and Bernard their $49 each. He doesn't owe anything else..

Where did the $2 go ?

sotong_sg, your phrasing is totally wrong. you can't just relate the "$1 in his hand" without including the other guy into the pic.

because if you were to include the other guy, there will still be the missing $1. this makes more sense when you say the last sentence.

so all in all, there will be a total of $99.

however, i have the solution to this question which i have no idea whether it is right or wrong.

$97 / 2 = $48.50

$(48.50 + 1) + $(48.50 + 1) = $99

$99 + $1 (remaining $1 on hand) = $100.

problem solved. it is all just the err in sentence phrasing i guess.

I was just trying to bring around the idea that the total value now is no longer $100, but $98.

He borrowed $100.

Then returned $2.

So he now owes $98. The $100 is no longer in the picture, forget about the $100.

So where did he spend the $98 ?

$97 in shoes, $1 on hand.

Basically there is no loss of money, except the question is designed to confuse ppl with the ins and the outs of money changing hands.

key phase is above, the $1 is already in the $98, so should not have add into the 98, that will be double entry...

In a 24 hour period, there are Two times the above happens, so minus two = 22
