A boy is out with his father and their car crashes. The father is killed and the boy is seriously injured. He's rushed to hospital and prepared for an emergency operation. The surgeon comes out and says "I can't operate on him, he's my son". How?

The Doc's his mum

If you add the letter 's' to this word it changes from plural to singular and changes gender. What is the word?

okay say you're a bus driver, and you're driving your bus. On the first stop 9 people get on, then on the next stop another 3 get on, at your 3rd stop 6 get on and 4 get off, and the 4th stop another 7 get on and 6 off and on the 5th stop 3 more get on and 2 get off, so.....

....whats the drivers name?

Nope, you can only put a weight onto the scales once and take one reading off it.

He stands on the scales and eats the bars one at a time. When his weight goes up by 110g, he has the offending bar

A manager of a factory has 10 conveyor belts churning out chocolate bars. One of the belts is giving out bars 10% heavier than the others, say 110g as opposed to 100g from the other 9. He needs to find out which one and fix the problem. However, he can only use the weighing scales once. How does he do it?

Spoiler:

Put one bar from belt one on, two from belt two, three from belt three, etc up to belt 10.
That will be 55 bars (which would be 5500g with problem fixed). Now take a reading. If its 10g more than this, belt one is the issue, 30g more then belt three is the issue, 70g more then belt seven is the issue, etc

westendgirlie · 31-05-2012 02:59PM

Oh that's very clever

Take 1 bar from belt 1, 2 from belt 2, 3 from belt 3 etc.
Weigh them all.

If the total is over by 10g its belt 1, 20g its belt 2, etc

(assuming a proper bar is 100 and heavier one is 110)

edit - damn you newport, got in before me *shakes fist*

Anyway...I like this one......

3 lads shared a house. One morning, one of them gets up. All there is to eat in the house are some sausages. So, he eats half the sausages AND half a sausage. Then he leaves. The next guy gets up. He eats half of the remaining sausages AND half a sausage. Then he leaves. The last guy gets up and eats half of the remaining sausages AND half a sausage. Then he leaves.
The third guy finished the sausages. There were no half sausages to begin with. None left at the end.
There were no half sausages left between guys eating.
How many sausages were there in the beginning?

You have three cups of coffee and 14 sugar cubes. You must put an odd number of (whole) sugar cubes in to each cup (and each cup must get sugar put in to it and all sugar cubes must be used). What's the answer?;)

1,1,12.

You put the cubes of sugar in in this order

first cup 3 cubes
second cup 1 cube
third cup 1 cube
first cup (again) 9 cubes

You said must be an odd number put in, you didnt say total number must be odd.

Sorry for hijacking the 'why' there but he got there before me with the right answer
