A large truck is crossing a bridge
A large truck is crossing a bridge
A large truck is crossing a bridge 1 mile long. The bridge can only hold 14000 lbs, which is the exact weight of the truck. The truck makes it half way across the bridge and stops. A bird lands on the truck. Does the bridge collapse? Give a reason.
No it does not collapse. Because it has driven a half mile - you would subtract the gas used from the total weight of the truck.

6 in roman
6 in roman
After teaching his class all about roman numerals (X = 10, IX=9 and so on) the teacher asked his class to draw a single continuous line and turn IX into 6. The only stipulation the teacher made was that the pen could not be lifted from the paper until the line was complete.
Draw an S in front of the IX and it spells SIX. No one said the line had to be straight :)
Chocolate Machines
Chocolate Machines
There are ten chocolate machines numbering 1 through 10 and each producing chocolate bars that weigh 1kg. However, there is a faulty machine which is producing 0.1kg more per bar than it should be.
There is one scale in the room that can only be used once to weigh the chocolate bars although a number of combinations is allowed.
How can you identify which machine is faulty?
Put one bar from the first machine on the scale, take two from the second machine, take three from the thrid machine, take four from the fourth machine and so one until such time that you have taken 10 from the 10th machine and placed them on the scale. Depending on which machine is faulty will be determined by the number reflected in the decimal column of your scale. For example -- if the thrid machine is faulty the final number will show 55.3kg's; if the seventh machine is faulty the final number will show 55.7kg's.
