Example 2.

Two Partners join together and are re∣solved to make up a Stock, viz. A and B. The first Partner A doth resolve to have 4/7 of the profit, and layeth in 1368 Pound. It is required to know how much B must pay into Stock to gain the remaining 3/7 of the profit.

By the Rule of Three, say, If 4/7 of the gain which the first man A taketh, did pay into Stock 1368/1, how much must 3/7 of the gain lay into Stock, which is the second man B profit, which by multiplying and dividing you will find to be 1026l. and so much must B lay into Stock to gain 3/7 of the profit, if A gaineth 4/7 by putting in 1368l.
