Farmer Doug sells his newly laid eggs to a local grocer.

If the farmer has 5 hens laying 6 eggs per day, 9 hens laying 4 eggs per day, and 10 hens laying 2 eggs per day, how many eggs would he have after 14 days ...

... if 3 of the 4-per-day hens were eaten by 2 foxes after 5 days, and 4 of the 6-per-day hens ran away after 4 days, but 3 of them were caught by the farmer's wife after 2 days, and 8 of the 2-per-day hens stopped laying after 3 days but started again after 1 day, and 3 of the 6-per-day hens produced 2 extra eggs per day for 4 of the 14 days, and 1 extra eggs per day for 7 of the 14 days, with 4 new 2-per-day hens added after 6 days to replace the 3 4-per-day hens that were eaten by the 2 foxes?


I have the answer here waiting to post ... ;)

What! ... you're sat behind a computer, use that ... pen-n-paper is for wimps.

Answer is quite easy. ;)

I've spent 50 odd years at it ... and I'm still wrong.

;)
 
Is it a proper maths question, or an answer so simple we will cringe? :D
 
Tut tut.

The answer is nill. Do I win something?

:)

Edit: So long as this is a conceptual question rather than a mathematical one...

You could join the grocer for a celebratory omlette:D! Well done tomesega, I missed that one completely!
 
Firstly, what does the first line have to do with it - eggs arent fresh after 2 weeks surely!

probably went totally wrong somewhere but heres my workings - please point out where i went wrong!! It was VERY hard!

Start @ 00:07

5 Hens @ 6 per day = 6x5...30. 30x14 = 420 eggs.

9 Hens @ 4 per day = 9x4...36 36x14 = 504 eggs

10 hens @ 2 per day = 10x2...20 20x14 = 280 eggs

Thats 1204 eggs assuming they were consistent for the 2 weeks...

BUT

3 of the 4 per day hens didn't produce for 9 of 14 days

so 3x4 = 12 x 9 = 108
1204 - 108 = 1096

BUT

4 of the 6-per-day hens ran away after 4 days, but 3 of them were caught by the farmer's wife after 2 days

5x6 + 5x6 + 5x6 + 5x6 + 1x6 + 1x6 + 3x6 + 3x6 + 3x6 + 3x6 + 3x6 + 3x6 + 3x6 + 3x6

30 + 30 + 30 + 30 + 6 + 6 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18

= 30x4days + 6x2days + 18x8 days

= 120 + 12 + 144 = 276

So... 420-276 = 144

So... 1096 - 144 = 952

BUT

8 of the 2-per-day hens stopped laying after 3 days but started again after 1 day

8x2 = 16 so 1 day of not laying = 16 less in total

So... 952 - 16 = 936

BUT

3 of the 6-per-day hens produced 2 extra eggs per day for 4 of the 14 days, and 1 extra eggs per day for 7 of the 14 days,

3(2x4)= 24 extra eggs

THEN

3 extra eggs a day for 7 days so 7x3 = 21

SO... 24+21 = 45 ADDED

So... 936 + 45 = 981

BUT

4 new 2-per-day hens added after 6 days to replace the 3 4-per-day hens that were eaten by the 2 foxes

So AFTER 6 days = 8 days with 4 hens laying 2 eggs a day = 8 eggs a day multiplied by 8 days

SO... 8x8 = 64

64 added to 981 = 1045

Finished at 00:30
 
Oh MAN!

I got screwed over...

thought about the first sentance again and if 2 week old eggs ARENT sold as newly laid, he would have got rid of them leaving him with an un-workoutable minimial stock, if any!

Git! ;)

Oh dear - Cambridge students, eh? I think I'm going to Bath uni, personally.

'Farmer Doug sells his newly laid eggs to a local grocer.'

Nobody said anything about eggs going bad. How do we know farmer Doug doesn't put them in the fridge?

I did more than cringe... more like lost the will to live using my brain only to find out 2 week old eggs aren't classed as newly laid, therefore deeming it a trick question.
 
Well I'm off to the Grocers place for some nice fresh omlette, followed by a nice pavlova I think... or maybe some meriengs (sp?)
