A garrison of 600 men has just enough bread to allow 24 ounces a day to each man for 35 days; but, with the news that the enemy was planning an attack, the garrison was forced to reinforce to 4 800 men. The enemy arrives and decides to enforce a siege - to reduce
their own loss of life. How many ounces of bread a day must each man in the garrison be allowed, to hold out 45 days against the siege of the enemy?
If the transport of 60 cwt. (hundredweights) of bread for 20 miles costs the garrison £14 \; 10\text{s}. (i.e. Fourteen pounds ten shillings), what weight can be carried 30 miles for £5 \; 8\text{s } 9 \text{d}?
n.b. in those days:
12d(pennies) = 1s (shilling)
20s = £1 (pound)
16 ounces = 1 lb (pound - "weight")
112 lb= 1 cwt
