There is, indeed, great variety in questions in this rule; but they may be all easily solved by a little consideration, and the following proportion, viz.-That the gains or losses, are in proportion as the quantities of goods. EXAMPLES. 1. Bought 30 hogsheads of molasses for 600 dollars ; paid in duties 20 dollars 66 cents, freight 40 dollars 78 cents, for storage 6 dollars 5 cents, and for insurance 30 dollars 84 cents: If I sell it at 26 dollars per hogshead, how much shall I gain per cent. ? $. cts. 600 $26 30 hhds. $780 00 Sold for. 698 33 Cost. :: 698 33 81 67 Gain. $. cts. $. cts. $. cts. 693 33 : 81 67 100 11 69+Ans. 2.

If I sell a cwt. of sugar for $8, and thereby lose 12 per cent. ; what shall I gain or lose per cent., if I sell 4cwt. of the same sugar for $36 ? Ans. I lose only 1 per cent. per yard? FELLOWSHIP. FELLOWSHIP is a rule by which merchants, &c. trading in company with a joint stock, determine each person's particular share of the gain or loss in proportion to his share in the joint stock. By this rule a bankrupt's estate may be divided among bis creditors; as also legacies adjusted when there is a deficiency of assets or effects. SINGLE FELLOWSHIP. Single Fellowship is when different stocks are employed for any certain equal time. RULE.*--As the whole stock is to the whole gain or loss, so is each man's particular stock to his particular share of the gain or losset PROOF.-Add all the shares together, and the sum will be equal to the gain or loss, when the work is right. EXAMPLES. 1. A and B gained by trade £182. A put into stock A $300 and B £100; what is each person's share of the profit? £ £ £ £ £. 300+400=700 : 182 : : 300 : 78 A's share. 700 : 182 : : 400 : 104 B's share. £182 Proof. { 2. A man dying, bequeathed his estate to his three sons in the following manner, viz. to the eldest he gave 1840 dollars, to the second 1550 dollars; and to the third 960 dollars ; but it was found his whole estate was no more than 1840 dollars; what is each one's proportion ? $778,2977 the first. Ans. 655,63), the second. 406,067, the third. 3. A and B companied ; A put in 450 dollars, and received of the gain ; what did B put in? Ans. $300. 4. Three merchants freight a ship with wine; A loaded 110 tuns, B 97 tuns, and C 133 tuns. In a storm the seamen were obliged to throw 85 tuns overboard; how much must each sustain of the loss ? Ans. A 274, B 244, C 334 tuns. C 5. Three men, A, B, and C, contract to build the hull of a vessel for 625 dollars; A works 100 days, and his work is estimated at 1 dollar 80 cents per day ; B works 1011 days, estimated at 1 dollar 60 cents per day; and C * That the gain or loss in this rule is evidently in proportion to their stocks, may be shown from the nature of the Rule of Three. + The first and third contractions of note 4 of the Rule of Three, are often the best for working questions in this ruley especially in decimals. work 98 days, at 1 dollar 50 cents per day : how much is each man's proportion according to his work? day. $. cts. days. day. $. cts. days. day. $. cts. days. 1:1 80 ::100 1: 1 60 :: 1011 1: 1 50 :: 98 100 150 1 011 180,00 A's work. 40 4900 98 147,00 16 489 162,00 $. cts. 489 : 625 :: 162 : 207,0583 489 : 625 : : 147 : 187,88.563 $. 8. $. cts. 489 : 625 180 230,06233 $230,06-29 A's share.

Ans. C put in his cloth at $21 per yard; B's part of {was , . L { DOUBLE FELLOWSHIP. Double FelloWSHIP is when the stocks are employed for different times. Rule.*-Multiply each man's stock by the time of its continuance; then say, as the sum of all the products is to the whole gain or loss, so is each man's particular product to his particular share of the gain or loss. EXAMPLES 1. A and B hold a piece of ground in common, for which they pay £36-A put in 23 oxen for 54 days, B 21 oxen for 70 days; what part of the rent must each man pay? 23x54=1242 21x70=1470 £. 19 10 32 B's.

Two merchants enter into partnership for 16 months A put in at first 1200 dollars, and at the end of 9 months 200 dollars more; B put in at first 1500 dollars, and at the expiration of 6 months took out 500 dollars—with this stock they gained 772 dollars 20 cents; what is each man's part of it ? Ans. A's $401 70cents-B's $370 50 cents. 3. A, B and C, enter into partnership; A put in 85 dollars for 8 months, B put in 60 dollars for 10 months, and C 120 dollars for 3 inonths; by misfortune they lost 41 dollars; what part of the loss must each man sustain?

At the end of 7 months, Thomas sold his share to White ; and at the end of the first year White sold the mill. They then made a settlement; and, the year's profit of the mill being ascertained at $260, what was each man's share ? Ans. Thomas's $54,16 cts. White's $205,83.4 cts. * When the times are equal, the shares of the gain or loss are evidently as the stocks, as in Single Fellowship; and when the stocks are equal the shares are as the times; but when neither are equal, the shares must be as their products. |
