LOSS AND GAIN, Is one of the imaginary accounts in Double Entry Book Keeping, and so called in order to supply the want of real or personal titles in recording gains and losses, which could not with propriety be placed to real or personal accounts. It is by this Rule, that merchants discover the gain or loss in business, and the rate per cent. in buying or selling goods. Q. What does the words buy or bought, sell or sold imply in this rule? A. Buy or bought, means the first cost of the goods, sell or sold, the sales made. Q. What does the first cost or invoice refer to? A. By taking the difference between the first cost and the sales. Q. How is a loss ascertained? A. When the amount sold is less than the first cost, take the difference, that difference will shew the loss. CASE I. First cost and a gain given to find the rate per cent. Rule.- Take the difference between the first cost and the sales. Then say as the first cost is to the difference, so is 100 to the rate per cent. Ex. 1. Bought coffee at 10 cts. per lb. and sold it for 12 cts., how much is the gain per et.? Ans. 20 pr. ct. Sold for 12 As 10 : 2 gain : : 100 = 20 pr. ct. Ans. CASE II. Given the first cost and a loss to find the rate per cent. Rule.- As the first cost is to the loss, so is 100 to the rate per cent. Ex. 2. Bought sugar at 8 cts, per lb. (which was damaged,) and had to dispose of it at 5 cts. per lb., how much is the loss per Ans. 374 pr. ct. : As 8 2 3 cts. loss : : 100= 37} pr. ct. Ans. 25 CASE III. To gain a certain per centage. RULE.--As 10 per cent is t' of a hundred, add it to the first cost. Thus, is of $1.00 is 40 cts. which added, make $4.40, the selling price required; or, agreeably to the common method, say as 100: 110 :: $4.00 = $4.40 as before. The first method is more concise, and therefore, the best. 1. Admitting I purchase cloth at $4 per yard, and wish to gain 10 per cent, how much is the selling price? 2. Bought calico at 20 cts. per yard, and want to gain 25 per cent, how much must be the selling price per yard? Ans. 25 cts. CASE IV. Selling price,gain andrate per cent given to find the first cost. Rule.--Add the gain per cent. to 100, then sày as 100 with the given per centage added, is to 100, so is the retail price to the first cost. 1. Suppose the retail price to be $5 per yard for cloth, and the gain 25 per cent, how much is the first cost? Ans. $4.00 per yard. CASE V. When a certain loss per cent. has to be sustained on the first cost to find the retail price. Rule.—Multiply the first cost by the given per centage, and divide by 100 for the amount of loss sustained, the amount subtracted from the first cost will give the result; or, as 100 : 84 : : 840 : $705.60 as required. Suppose I purchase a lot of goods for $840, at auction, and owing to their being damaged, have to sustain a loss of 16 per cent below the first cost, how much will they be sold for? Ans. $705.60. CASE VI. To find the profit per pound, per yard, &c. when the first cost and sales of a certain number of yards, pounds, cwts. &c., are given. RULE.—Find the whole gain, and divide it by the number of yards, pounds, or cwts., &c. Ex. 5. Bought a chest of tea, containing 340 lbs. for $289, and sold it for $408, what was the profit on each pound? Ans. 35 cts. per lb. CASE VIL When there is a loss per cent. sustained by the sale and the first cost is required. RULE.—Subtract the rate per cent. from 100, then say as 100 less the rate per cent. is to 100, so is the amount of the sale to the first cost. Ex. 6. Sold a lot of dry goods for $540, and had to sustain a loss of 10 per cent., what did they cost me? Ans. $600. CASE VIII. When you purchase goods and wish to gain a certain sum on the whole purchase, so as to be able to sell them at a certain per centage. Rule.--Add the sum you wish to gain to the amount of the purchase, then divide that amount by the number of yards, pounds, and cwts. for the answer required. Ex. 7.
