The questions given in these col
umns from time to time, afford an
excellent review for persons desirous
of reviewing Their studies. They
show to persons contemplating teach
ing, the nature, and something of
the extent of an examination. With
pleasure it is noted, that many who
have long since LAID aside their
school books, read these lists, and
find therein, occasionally, questions
tor mental recreation.
The correctness of the answer
given to No. 4, first-class arithmetic,
is doubted by some.
Sollution.-The person who holds
the note, at the end of the first year,
will receive $500, the payment $500
plus one years interest on the face
of the note at 8 per cent; at the end
of the second year, he Will receive
5000, the payment, $500 plus the in
terest on $4,000 for one year at s per
cent; at the end of the third year,
he will receive sl296, the payment
plus the interest on $1,000 for one
year at s per cent; that is, the note
will yield, at the end of the first,
second, and third years, respectively,
500, $3.50, and sl296. The pur-
chaser-we will call him P.-must
receive 10 per cent. on his invest
ment for each year. At the end of
the first year, he must receive the
amount of his investment for that
year; so for the second and third
years. To find the amount, we null
tiply by plus the rate. In this case
then by l plus one-tenth, IL. In
this question, the present worth is
the unknown quantity. Call 1t X, or,
as we do in the cases in percentage,
and in many of the applications Of
percentage, call it 100 per cent; that
is, any number is once itself. Then
P's. investment for the first year is
100 per cent, and, as he is to receive
10 per cent. of this, the amount of his
investment at the end of the first
year is ITO per cent, that is IL
times the present worth of the note.
The yield of the note each year must
reduce the investment for that year.
At the end of the first the note yields
800. At the end of the first year,
the difference between the amount
of the investment, and the yield of
the note for that year, is P's. invest
ment tor the second year; then P's. in
vestment for the second year is 11O
per cent. of the present worth less
the yield of the note,=1.1-s7oo.-
P's. investment for the second year,
l.l-s7OO, plus 10 per cent. of the
same-(l.l-s7oo) q plus 12)-Q.l-
$7OO) l.l-square OF IL, plus $40
is the amount of P's. investment al
the end of the second year. The
amount of P's. investment at the end
of the second year, less the yield OF
the note for the same year, is P's
investment for the third year; then
the square of l.l,-S77O-s96O=square
of IL, less $3.50. The amount OF
P's. investment at the end of the
second year less the yield of the note
for the same time, is P's. investment
for the third year-square of ,less
$3.50. P's. investment for the thirG
year-square of IL, less $3.50, mul
tiplied by plus +, by l.l,=(squart
of IL, less Sl720) IL, is the amount
of P's. investment at the end OF
the third; then the cube o.
IL, less sl90a, is the amount of P's
investment at the end of the third
year. This amount less the yield o.
the note for the third year, is P's
investment for the fourth year. Ther
P's. for the fourth year equals the
cube of IL, less $l9O3 less $l296
equal to the cube of IL less S3l99
But this investment must equal zero
since the note is paid up at the enc
of the third year. Then we have the
cube Of IL times the proceeds of the
note, less s3l99 equal to zero, or the
cube of IL times the proceeds=sl,

solution is, ($7OOxl.21 plus s96Oxl.l l
plus $l296) divided by 1881, equa
to S2403. .46-.
