The distance of Cork from Belfast is, suppose 204 miles: two travellers set out in order to meet, one from Cork the other from Belfast, they meet at the end of 4 days, when it appears, that the traveller from Cork has gone 3 miles per day less than he from Belfast; how many miles did each of them travel per day? , 155. Suppose I bought 2 pieces of grey linen, the one 63 yards, at the rate of 9 yards for a pound, the other 54 yards at the rate of 12 yards for a pound; but unexpectedly being called on for a sum of money, which not having, I sell both pieces at 21 yards for 21; whether do I gain or lose, and how much P 156. If 5 men, or 8 boys, can do a piece of work in 3 days: in what time could one man and one boy together perform it P Here it is plain, that in 3 days one man will perform + of the work, and a boy # of the work in the same time. Therefore, H = 3 days work for a man. + = 3 days work for a boy. 43 = 3 days work for a man and a boy. 13 : 40 : : 3 days. 3
157. Suppose the proportion of mens’ work to boys to be the same as in the last question, and that 5 men and 8 boys can perform a piece of work in 13 days; in what time would 8 men and 5 boys perform the same piece of work?

160. Two merchants entered into partnership, and each put in 20 pieces of cloth; but one of them had a better quality than the other, and cost 4l more per piece; the cloth being sold, they find they have gained 1021 10s. of which he that had the worst quality received 461 5s. for his part of the gain; how much per piece was each of their cloths valued at 7 161. Two merchants buy certain goods, the one advances 80l, the other 105l, they gain on sale of them 741; what is each man's part of the gain :
162. Three persons went into trade, with the respective cas pitals of 26300, 250, and 350; their joint profit at the end bf the year was 5001; what was each man's part of the gain? 163. Two merchants made a stock of 1200l., of which one contributed 750l and the other the remainder, they gain 300l; what is the share of each 164. Divide 1541 in the proportions 2, 3 and 4 respectively. 165. Divide 1541 in the proportions +, + and + respectively. 166. A piece of ground of 45a. 2r. 20p. is to be divided between 3 sons, of which the eldest is to get #, and the remainder to be equally divided between the other two: what is the share of each * 167. A ship, worth £1960 being lost, of which A had #, B #, C or and D the remainder: what will each partner lose if £1200 of the value be insured? 168. Three persons, A, B and C purchase a ship, of which A advanced #, B 3 and Cthe remainder, which was 350l; what part of the vessel had C, and what money did each of the others put in P 169. Divide £240 between 3 persons, in the proportions of 1, 2, 3, respectively. 170. Three merchants enter into partnership, their joint stock was £3440, they gain 4051, which they divide equally; what did each put in, having continued in trade 5, 6 and 9 months respectively :
Here, as the gains are equal and the stocks required, no notice need be taken of the gain, in solving this question, and it is evident, that the less time each man’s money was in trade, the greater the sum of money he should employ, therefore, proceed thus ; find the least common multiples of the numbers 5, 6 and 9, which is 90. --Whence, 90 + 5 = 18.) The direct propor90 -i- 6 = #} tions of the respec90 -i- 9 - 10 J tive stocks. Then, as 18 + 15 + 10 = 43 : 18 :: 3440 : 1440 43 : 15 : : 3440 : 1200 43 : 10 :: 3440 : . 800 And the answers are 1440l., 1200I, and 800l respectively. Or, by taking the gain into consideration, 405 + 3 = 135 each man's gain.
and ; .# = # The direct proportions
135 + 9 = 15 of the respective stocks
Which numbers being in the same proportion as the former will give the same result. - - 171. A, B and C have had capitals of 2000l., 3000l, and 4000l., in trade 12, 9 and 7 months respectively, at the years end they have to divide 2133 l ; what is each man's part? 172. Three merchants, C, D and E have gained 340l when the profit of C is multiplied by 2, that of D divided by 3 and that of E increased by 20, the results will be equal; what was the share of each 2. Here it is plain that D's part is six times A's, and E’s onethird of C's less 20l. - - - Then C will have 1 part D will have 6 parts and E will have 2 parts less 20!. . . and adding 201 to the given sum, we have to divide 360l into parts as 1, 6 and 2 respectively. * : Whence C's part is 401, D's part 2401, and E’s 80–20= 60l the answer required 2 : 173. Suppose, as in last question, but the share of C to be divided by 2, that of D to be multiplied by 3, and E’s increased by 20 as before; what is the share of each P 173. In this question the parts are 6, 1, and 3-20; therefore, adding
20 to the given sum and proceeding as above, the answers are readily obtained.
