Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...3, because 3X$60=r$180; by the second method we added on J, because 60da.-(-0da.=75da. N. B.--When advantage can be taken of both time and principal, if the student wishes to prove his work, he can first work it by the Bankers' Method, and then by taking advantage of the principal, or vice versa. And as the two operations are entirely different, if the same result is obtained bj fta/ih, he may fairly conclude that the work is correct On all notes that bear $12 per annum, or any aliquot part or multiple of $12. If a note bears $12 per annum, it will certainty bear $1 per month; hence the time in months would be the interest in $; and the decimal parts of a month would be the interest in decimal parts of a $; therefore when the note bears $12 per annum we have the following rule: Rule.--Reduce the years to months, add in the given months, and place one-third of the days to the right of this number, and you have the interest in dimes. Example 1.--Required the interest of $200 for 3 years. 7 months, and 12 days, at 6 per cent. 200 i of 12 days=4. 6 Ti. Me. Da. S12.00=int. for 1 yr. 3 7 12=43.4mo. Hence 43.4 dimes, or $43.40cts., Ans. We see by inspection that this note bears $12 interest a year; honce the time reduced to months, with one-third of the days to the right, is the interest in dimes. If this note bore $6 a year, instead of $12, we would take one-half of the above interest; if it bore $18, instead of $12, we would add one-half; if it bore $24, instead of $12, we would multiply by 2, etc. Example 2.--Kequired the interest of $150 for 2 years, 5 months, and 13 days, at 8 per cent. 150 of 13 days=4t. 8 Tr. Mo. Da. 812.00=int. for 1 yr. 2 5 13=29.4$moa. Hence $29.4J dimes, or $29.43J cts., Ans. We see by inspection that this note bears...
