To calculate interest by the preceding table; RULE. Multiply the sum by the rate per cent. and that produ& by the months, weeks or days given; then cut off the two last figures to the right hand, and enter the table with what remains to the left; against which numbers, collected, is the interest for the given sum. Note. For every 1 cut off in months, add 2d. for every 10 in weeks, add 1d. and for every 40 in days, Iqr. EXAMPLES. 1 What is the interest of 24661 16s 6d. for 10 months, at 4 per cent. per annum ? £. s. d. 2466 16 6 £.s. d. 4 2 What is the interest of 2467/ 10s. for 12 weeks, at answer 281 9s. 5d. 3 What is the interest of 24671 10s. for 50 days, at 6 To find what any estate from 1 to 50000l. per annum will be for a month, or a day; RULF RULE. Collect the suras from the table opposite the given numbers for the answer. EXAMPLES. At 3651. per annum, what is that per day; also 16 3 3 month; 300 51 per £30 8 4 per month. To find the amount of any income, salary or servant's wages, for any number of months, weeks or days, RULE. Multiply the yearly income, or salary, by the number of months, weeks, or days, and collect as before from the table. EXAMPLE. What will 270 per annum come to for 11 months, for 3 weeks, and for 6 days, separately and collectively? A TABLE Of Days for any given time less than a Year.

First, To know the number of days, from the beginning of the year, to any given day of any month: This is obtained by inspection only. Secondly, To find the number of days from any day in any month to the end of the year : Suppose from 10th 9mo. Thirdly, To find the number of days between different dates: Suppose the 9th of the 5th month, and the 5th of the 11th month. From the number answering to 5th 11mo. Remains 309 129 Days 180 Fourthly, To find the number of days from a given date, to some other in the year following: Suppose, from 12th 10mo. to 10th 6mo. ensuing. Note If the intercalary day of a leap year intervene, one day must be added to those found as before, COMPOUND INTEREST. Compound interest is that which arises from a principal increased by its interest as the interest becomes due. RULE |
