I think you're off a bit.
I'd put the answer at 12 pounds.

if a brick weighs 4pounds and half a brick
  then what does a brick and a half weigh ?

i.e.        b = 4 + Żb
=>     Żb = 4
=>        b = 8
=> CliffordK is correct

  Well done Clifford    the answer is indeed 12 pounds     its a simple algebra question made tricky by its wording...   the question is basically    What is the weight of a the brick ?

This one has caused a helluva rumpus in work  even amongst academics ..its only when i DREW it on a board as a seesaw   with a brick on one side.. balanced by a half brick and a 4lb weight on the other that SOME people started to get it !!!!

There was an old (probably first world war vintage) puzzle that went: "If a hen and a half laid an egg and a half in a day and a half, how many eggs would a rooster lay in a week?". That was, of course, the easy one. The harder variant went: "If a hen and a half laid an egg and a half in a day and a half, how many eggs would a hen (working at the same rate) lay in six days?"

Your second question - and PippySD's OP are important.  Algebra is great -  I love it - but it is of little use if you cannot take real world lumpen phrase and represent it algebraically

Based on all of this, can you tell me then, how much milk is in a bar of Cadbury's Dairy Milk?

Hmmmm

So, the question is which half of the wishbone did the half a hen have.     :-\

So, algebraically, one gets...
R = the number of eggs laid by the rooster...
E = the number of eggs laid in 6 days.
H = the number of eggs that 1.5 hens lays in 1.5 d.
So, it would be

E =10xR + 4xH   :o

So...
One must conclude E=6  eggs laid by one hen in 6 days.  ::)

As a firm believer in empirical study I took a bar of choccy and asked a cow !....The cow consumed the choccy and then did a cow pat !....so...I reckon it's about 2 litres !

*broken English mode* Cow eat wrapper too.....silly cow !!





Bona- fide non-doctored piccy of cow eaty choccy !

so there are the Eggs and the Rooster, but the Rooster will lay 0  -- Rooster is the key, because when we cancel the lower case we arrive at
ERR0R
and we can conclude that the answer must be 4 eggs, not 6!

Nobody said the answer  was 720
