Puzzles and Curious Problems by Henry Ernest Dudeney: $8$
- Equal Values
- A lady and her daughter set out on a walk the other day,
- and happened to notice that they both had money of the same value in their purses,
- consisting of three coins each, and all six coins were different.
- During the afternoon they made slight purchases,
- and on returning home found that they again had similar value in their purses made up of three coins each, and all six different.
- How much money did they set out with, and what was the value of their purchases?
Solution
The two ladies had:
- $10 \shillings$, $1 \shillings$ and $6 \oldpence$ in one purse
and:
- $5 \shillings$, $4 \shillings$ and $2 \shillings 6 \oldpence$ in the other.
That is, they had $11 \shillings 6 \oldpence$ each.
They each spent $4 \shillings$ and returned with:
- $5 \shillings$, $2 \shillings$ and $6 \oldpence$ in one purse
and:
- $4 \shillings$, $2 \shillings 6 \oldpence$ and $1 \shillings$ in the other.
They started with $11 \shillings 6 \oldpence$ each and ended with $7 \shillings 6 \oldpence$ each.
