" . . . 208. Sold goods for 75, and lost thereby, 10 per cent though 1 ought to have cleared 12% per cent; how much under their just value were the goods sold 2 - 209. Sold to A 20 hlids. of flaxseed, by which I have gained 74 per cent; these A sold to B at a profit of 24s, per hbd. ; and B sold them to C for 115l 10s. by which he gained 5 per cent; what did 1 pay for the flaxseed per hlid.” 210. lf 5 gallons of brandy be worth 8 gallons of rum, and 3 gallons of rum be worth 4 of whiskey; what is the price of each per gallon, the price of 3 gallons, taking one of each, being 21 1s. 10%d. ? - PRACTICE Is a compendious method of finding the value of any quantity of goods, by the given price of one of the said quantity. It is performed, by supposing the given quantity to be units of the highest denomination of the given price, and by separating the price into aliquot parts of the integer, of which it is a part or parts, and dividing the given quantity by the denominators of those parts, the answers to such questions as commonly occur in business, are found in an easy and con cise manner. * Note –An afiquot part of any number is such, that being taken a certain number of times, will exactly make up that number, thus 4 is an aliquot part of 12, and 3s, 4d, or 40d, an aliquot part of a pound sterling. 3 . . . . . . . . .* 2 00 . . . . ... +'s #.... ------ +++ *Note—The aliquot parts of alb, Troy are nearly the same as those of a shilling, The different variations of this rule are so numerous, that it would be tedious and perhaps impossible to enumerate all of them, and some would not beeutitled to the epithet of conciseness; the annexed are, I hope, as unexceptionable in this way, as any that have been yet adopted. Case 1st.—When the given price is a part or parts of a penny, consider the given quantity as pence, and divide by the denominator or denominators of the aliquot part or parts of a penny, which will give the answer in pence. * One farthin o of a £ sterling, therefore, when the price is #, divide by 12 and 80. one halfpenny being ++g of a £ sterling, therefore, when the price # being s:g of a £ sterling, therefore, divide by 8 and 40. CAss 2d.--When the price is an aliquot part of a shilling, and also of a pound. If the given quantity be small, consider it as shillings, and divide by the denominator of the given aliquot part of a shilling, which win be the answer in shillings. If the given number is large, consider it as pounds, and divide by that aliquot part of a pound, of which the given price is a part; this will give the pounds of the answer, and the remainder divided by the denominator of the given aliquot part of a shilling, will give the shillings; the remainder, if any, wilf be so many ones of the given price.” CAse 3d.—When the price is the complement of a shilling. Divide the quantity considered as shillings, by the denominator of such aliquot part as the remainder may be after subtracting the given price from a shilling, which subtract from the given quantity, the remainder will be the answer in shillings Practice can always be proved by the Rule of Proportion, and in general, a case can be found by which an other can be proved by a different operation. - -* |
