Maths is not my strong point
Another one. I buy one type of tea (A) at £24/17/0 per cwt and blend it with another type (B) which costs £33/19/0 per cwt in the ratio 5A:3B.
To the nearest farthing, at what price per lb should I sell it in order to make a profit of 10%?
NB - for youngsters:
1 cwt = 8 stone
1 stone = 14 lb
20 shillings = 1 pound
12 pence = 1 shilling
4 farthings = 1 penny.

To answer VFTC's (1046) question, purely hypothetically, and nothing to do with my own experience, as far removed as can be imagined from my daily activites now or at any time in the past, and as far as I know (and I don't) not connected with real-life practices and methods anywhere:
Suppose you've been asked to provide information on encapsulated (ie, internal parts embedded in resin) battery packs found with captured equipment. X-ray analysis tells of the two variants tells you that two types of cell, short and long, are used in series. Pack A contains three long and two short, and provides 12V at the terminal. Pack B contains five long and six short, and provides 24V. What voltages are the short and long cells? For a bonus pint*, what is the likely battery chemistry and why are the packs badly designed?
I'll get me coat.

* Prize will be forfeited if not personally collected within two days. No cash equivalent. Not transferable. Pub may contain nuts. Freshly brewed coffee may be hot. Travel, food, accommodation and insurance not included. Your home is at risk if you do not keep up with payments. The location of the prize will be withheld for security reasons.

I make the answer 29. Do I get a gold star?
edit to say in my eagerness to get the answer I totally missed the second page of posts and therefore did not see the answer. Honest Sir, please dont send me to the Headmaster for a caning!

adr:
Short cell 1.5v, probably alkali manganese
Long cell 3v, probably lithium manganese
Poorly designed due to non-uniform discharge characteristics.
Oggin aviator - see me after prep!

Depends what you mean by "to the nearest farthing".
5/6½d (five and sixpence ha'penny) a pound is the nearest to the exact answer, but realises slightly less than 10%. To the nearest farthing producing at least 10% (in fact slightly more than) you would need to charge 5/6¾d (five and sixpence three farthings) a pound.

Quite right - 5s 6 3/4d per lb is the closest value to achieve a profit of 10%!
Take a gold star and an intimate session with the assistant matron in the sanitorium dispensary!!

Thankyou BEagle, that was an enjoyable 20 min with a spreadsheet
Though of course that assumes (1) you sell all the tea you blend and (2) have no other overheads, such as advertising, storage, travel time, equipment etc.
My geography teacher though we were the smartest race in the world because we continually had to do LSD and ft/in problems in our heads. Perhaps the decline in our civilization mentioned in various JB threads suggests she was (partially at least) correct.

Was said UAS dude trying to answer the maths question inverted at night on STBY generator having suffered structural damage from previously repored fire with a fuel imbalance and icing while trying to compensate for PEC for the forthcoming comm out ILS without the main ADI.....then its OK if he got it wrong.
