Interesting, Cathal, You have put a link to a site with a "bricks" teaser just like mine, and obviously you will have taken not the they posted theirs on March 25 2002 a whole 8 days after I posted this. Thanks, I shall contact them to complain bitterly on your behalf.

OK I can't see the March 25 date you are talking about. The point is that if they did copy it from you, its impossible to tell, because you copied it from somewhere else. You only changed the numbers. Appart from that its word for word. You are still trying to claim its your own?

it was part of my maths A level in 1985. There happy?

i didnt get why the other half is ten. suppose it could be 4? no one said it has to be 10!

Dina_2002 -- half is the whole thing divided by two, therefore the other HALF must be 10 if not it would not be a HALF would it??? =¬(

If there's one bad bricks teaser, I haven't heard it!

seen this on far many occasions to appreciate

If that was part of your A Level Maths, you must have crazy easy math in the UK or wherever!

And it is really the same teaser as #726 by "vikass" in section Math.

let x = the weight of one brick in pounds

x = 10 + ½x

1x - ½x = 10

½x = 10

2(½x) = 2(10)

x = 20 (pounds)

let y = the weight of one and a half bricks in pounds

y = 1½x

y = 1½(20)

y = 30 (pounds)

x = 10 + ½x

1x - ½x = 10

½x = 10

2(½x) = 2(10)

x = 20 (pounds)

let y = the weight of one and a half bricks in pounds

y = 1½x

y = 1½(20)

y = 30 (pounds)
