I'm having a great time playing on my daughters DSi on Prof Laytons Curius Village. For those that like puzzles....


1. On an analogue clock. How many times does the minute hand cross the hour hand between 12 noon and 12 midnight?

2. A market trader is offering a camera and case for £310. The camera costs £300 more than the case. A guy wishes to buy the case only and gives the trader £100. How much change should he get in return?

1) the hands will cross at approx:

1.06pm
2.11pm
3.16pm
4.22pm
5.28pm
6.30pm
7.37pm
8.44pm
9.48pm
10.54pm

and that's it I believe.; 10 in total. They won't cross after that as they will meet but not cross at 12 midnight

2) Simple maths this

x = case

therefore x + (x + £300) = £310

therfore 2x + £300 = £310

therefore 2x = £310 - £300

therefore 2x = £10

therefore x = £5

cost of case = £5 (presuming there wasn't a discount for buying the package of camera and case)


I presume this is correct wires71?

I was bullied. Still I got my own back years later.

How? I like stories of how the bullies get their just desserts.

Kids who bully are usually themselves bullied therefore victims of circumstance. To hold onto their sanity/ego/selfworth some transfer their pain onto others. Kids emotional development isn't exactly err developed. Given support/goals/focus can help vastly in their future life. To get your own back years later on what was technically a child makes you no better. If the lad that knocked me about all them years ago came to me for a job i would treat him completely fairly. I don't see the point of holding a grudge against a child

Superb game. 2000 years old, simple rules, incredible strategies. In my view it makes chess appear like Kaplunk

I have always been a big fan of Othello. Or Reversi as some uneducated types like to refer to it.

4 sided house, window on every side pointing the same direction. Bear walks past the house.

A ladder hangs over the side of a ship anchored in a port. The bottom rung touches the water. The distance between rungs is 20 cm and the length of the ladder is 180 cm. The tide is rising at the rate of 15 cm each hour.

When will the water reach the seventh rung from the top?
