Note. When goods are bought or sold on credit, we must find, by discount, the present worth of their price in order to calculate the true gain or loss.

FELLOWSHIP

is a rule by which persons trading in partnership adjust their accounts so that each may have his share of the gain, or sustain his share of the loss, in proportion to his share of the stock. Also, by this rule a bankrupt's estate may be divided among his creditors.

SINGLE FELLOWSHIP İs when the several shares of stock are continued in trade an equal term of time.

RULE.

As the whole stock, is to the whole gain or loss, so is each man's share of the stock, to his share of the gain or loss.

EXAMPLES.

1. Three men, A, B and C, traded in company ; A put in $200, B $400, and C $600 ; they gained $348: what was each man's share of the gain ?

As gain B's gain. C's gain.

A's stock $200
B's stock 400

1200 : 348 :: 200: 58 C's stock 600

1200 : 348 ::

: : 400 : 116

1200 : 348 :: 600 : 174 Whole stock 1200

In this example, the whole stock being $1200, A's stock $200=ă of the whole, thus 20%=; B's stock $400=} of the whole, and C's stock $600=1 of the whole ; then

of $348=$58, A's part : } of $348=$116, B’s part, and of $348=$174, C's part, as before. Or, we may first find the gain on $1

Thus, 1200 : 348::1:0,29; then A's stock 200 X,29 =$58, A's gain ; B's stock $400 x ,29=$116, B's gain ; and C's, stock $600 X,29=$174, C's gain.

Proof. It is evident that if the several shares of gain oi loss, added together, be equal to the whole gain or loss, the work is right. Thus, $58+$116+$174=$348, the whole gain.

2. Three merchants, E, F and G, gained by trading in company $300 ; E's stock was $300, F's $600, and G's $900; what was the gain on $1, and how much was each man's share of the gain ? Ans. The gain on $1 is $£; then, £ of $300=$50, E's part; d of $600=$100, F's part, and of $900=$150, G's part of the gain.

3. A and B trade in company; A puts in $1250, and B $850. They find they have gained $700; what is the gain on $1, and what is each one's share of the gain?

Ans. $}. and A's $416,666+ B's $283,333+ 4. Four men, A B C and D, shipped 1150 barrels of flour; A put on board 150 barrels, B 200 barrels, C 500 barrels, and D 300 barrels ; in a storm the seamen threwo overboard 325 barrels; what number of barrels did each lose ? Ans. A lost 4216, B 5628, C 14116, D 8426

5. Two men, C and D, join their stock and trade in company ; C put in $650 and D $550. They gained $300 what is each man's share of the gain ?

Ans. C's $162,50, D's $137,50. 6. A bankrupt is indebted to A $375, to B $125,50, to C $110, to D $695,50, and to E $294, and his whole es:

tate amounts to only $1200, which he gives up to his creditors ; what must each receive in proportion to his claim?

Ans. A $281,25, B $94,121, C $82,50, D $521,62}, and E $220,50.

7. Divide $1850 among 5 persons so that their shares shall be to each other as 1, 2, 3, 4, 5.

Ans. $123,33}, $246,66%, $370, $493,331, $616,66 8. Two partners, C and D, trade with a capital of $3500 ; C put in $1950 and

the rest.

By misfortune they lose $700; what was D's stock, and how much is each one's share of the loss ?

Ans. D's stock $1550, and C's loss $390, D's $310. 9. Two merchants, E and F, traded in company and gained $875. E put in $1150, F put in so much that his share of the gain was $300; what was F's stock, and what was E's share of the gain ?

Ans. F's stock $600. E's gain $575. 10. Two men, B and C, traded in company with a joint capital of $1350. They gained $450, of which B took $300, and C the remainder; what was each one's stock ?

Ans. B's stock $900. C's $4504 11. C, D and E drew a prize of $2500, of which C is to have 5 shares, D 8 shares and E 7 shares; what is each man's part ?

Ans. C $625, D $1000, E $875:

COMPOUND FELLOWSHIP. When the several stocks, &c. of the partners are continued in trade an unequal term of time, it is called Compound, or Double Fellowship.

RULE.

Multiply each man's stock, or share, by the time it was continued in trade.

Then, as the sum of the products, is to the whole gain or loss, so is each man's product, to his share of the gain or loss.

EXAMPLES.

1. Two men hired a pasture for $24 ; A put in 6 cows for 4 months, and B 12 cows for 3 months ; what ought each to pay ?
