I have a book called Tutorial Arithmetic dated 1906. Here is a problem from the ratio and proportion section:
1) An Indian officer, whose annual pay was estimated in rupees, lost £41 12s. 6d. in one year by a fall in the value of a rupee from 1s. 1½d. to 1s 10¼d. What was his salary, estimated in rupees?
Here's another:
2) What is the value of 1 lb Troy of silver cut from a bar weighting 400 oz and worth £50 16s. 8d?
These are the sort of arithmetic problems students had to work out in 1906!

Sorry
Ha ha your post doesn't make sense now!:)
I know there's 16 oz in a lb so could that far in the second one but that far only. I'd have to take £50 16s. 8d, divide it by 400 then multiply that by 16. Not too difficult if I only knew the correct money units. Even so, I'll give a rough answer of just over £2 if I haven't made a mistake or misread the question.
I'm not sure though how a rupee can be classed as having fallen in value when it was worth 1s. 1½d to 1s 10¼d
isn't that a rise in the value of the rupee not a fall ?
PS: I see swingaleg beat me to it.
PPS: The second question would catch most people out, since there are 12 Troy ounces in a Troy pound, not 16. (I had to look that up!)
*claps enthusiastically*
almost a pity I actually quoted you
Oops, then my attempt at answering that question further up the thread would have been wrong.
The value of the rupee should have been 1s. 11½d.
Is that the actual book you used in school. Bought brand new?
Using arithmetic, I will now go and calculate my lifespan after that comment.
The pattern on the books was weird in the light, it had paler red ripples.
silvine?

I just know there's one in the attic somewhere with some dreadful poetry in it
assuming that's the case I make his salary 7992 rupees......
I loved those books. The info came in handy at a quiz the other night.
Q. What has five pieces of wood at the end of a chain?
A. Cricket pitch
I suddenly remembered that there were 22 yards in a chain.
Two farthings to a ha'penny,
Two ha'pennies to a penny.
Three pennies to a thep'ney bit,
Two thre'pney bits to a tanner.
Two tanners to a bob.
Two bob to a florin.
A florin and a tanner to a half crown.
Four half crowns to a ten-bob-note (the full crown wasn't generally seen in circulation).
Two ten-bob-notes to a pound
A pound and a bob to a guinea.
Decimalisation was a long time coming, mostly because people were worried that it might make things too complicated.
