Brain Teaser Game!


cornerstone

Recommended Posts

I have a bunch of cards with some brain teasers on them. A few of them are good, some of them are easy, quite a lot of them are annoying. I figured that whereas the annoying ones are normally, well, annoying - they could provide a bit of scope for some funnies too.

So feel free to play along, or wind everyone up as well. There is only one rule: the 'right' answer is always what is written on the card. Take it as a given that I agree with you that there were a million better answers - it's us versus the quesion card for shits and giggles.

Here's a relatively easy and uncontroversial clock-related question to start things:

TwoTone has a clock that chimes on both the hours and the half hours. The clock strikes once for each half hour, once for one o'clock, twice for two o'clock, three times for three o'clock, etc. As TwoTone commando rolled into his house one day, he heard the clock chime once. A half hour later it chimed once again. A half hour later it chimed once, and a half hour later it chimed once again. Since the clock is working properly (of course), what time was it when TwoTone entered his house?

Okay....! As I said, you have to get what is written on the card! :)

A survey was conducted of all the various mechanical modes of transportation people use to get to work each day. What did it find was the most common form of transportation?

Oh all right........................their legs.......................goodnight

Ok then when you factor in the Asian countries I would have to agree with the bicycle.

Now here's a question, has anyone ever had a prob tracking down their car in a large mall carpark.

Ok so these Asians often work in factories with many hundreds of co-workers who all ride in on bikes (many identical), so how do they find their bike's at the end of the day? :blink:

I´d guess it´s an elevator...

Good answer ;)

Just to explain my original answer, the question only stated mechanical there was nothing pointing to man-made,

so I chose Bio-mechanical...............yes I know it's not on the card and I will play by the rules :)

And the card says.....

"The lift"

WINNER! :thumbsupsmileyanim:

Good work! Every point made, by the way, was a good one. I'm sure that about 3% of domestics are caused by brain teasers. By comparison, 72% are Ikea-related.

Okay I have another one:

Imagine a bridge 4 km long and strong enough to hold 10,000 kg, but no more. A loaded transport truck weighing exactly 10,000 kg drives onto the bridge. At the half way point, a sparrow weighing 30 g lands on the truck, yet the bridge doesn't collapse. How could this be?

Because the truck is moving, 10,000kgs is the trucks stationary weight.

Intriguing idea. The quick answer is: that's not what the card says.

I actually googled around for this to satisfy my own curiosity - there is obviously a relationship between speed and mass in E=mc2.

The answer appears to be that moving objects actually increase in mass (but only by the tiniest amount until you hit the speed of light) as speed increases.

To give you an idea of how small the increase is: a 100,000 kg jet travelling at 2,000mph would increase in mass by only half a milligram (roughly). All news to me!

Any other suggestions out there for the truck? :)

Ok I have just found out that your sparrow is too big, they average 22.5 grams with the big fat ones tipping the scales at 29 grams.

So I don't think your 30 gram sparrow exists...........so there :bleh:

Ken :D

Elementary my dear Watson. The sparrow landed upon the truck when it was precisely over the mid-span support tower. The bridge span wasn't supporting the truck+sparrow, the brick columns were.

Nice thinking - but again it's not what it says on the card...

The truck weighed the limit when it got on the bridge but, as all motor-sport fans will tell you, the weight at the end of a race is lower than at the beginning. This in particular is why Valentino Rossi is better at the end of a race than at the beginning, as the fuel-tank is less full and therefore lighter.

The truck used 30g of fuel to get to the midway point.
