First, find the total ounces of bread.
$600 \times35 \times24$ ounces $= 504000$ ounces
Now, find the new number of men-shares needed.
$4800 \times45 = 120000$
Divide $504000$ ounces by $120000$ to get $2 1/3$ ounces a day.
Hence, each man must only eat $2 1/3$ ounces of bread a day.
$£14 10\text{s} = 290\text{s}$
$£5 7/16 = 108.75$ shillings
| Weight (cwt) | Distance (miles) | Amount (shillings) | |
|---|---|---|---|
| $60$ | can be transported for | $20$ | for $290$ |
| $1$ | can be transported for | $20$ | for $290/60 = 29/6$ |
| $1$ | can be transported for | $30$ | $(29/6)\times(30/20)\text{s} = 7.25$ |
| $(1/7.25)$ | can be transported for | $30$ | $1$ |
| $108.75 \times (1/7.25)$ | can be transported for | $30$ | $108.75$ |
Since $108.75 /7.25 = 15$
Hence, $15$ cwt can be carried for $30$ miles at a cost of $£5 7/16$
