Arithmetic, Continued.
Seventh.

must it be marked SO that the
merchant may discount 20 pei
cent and make 25 per cent profit
BY multiplying $s.75 by 25 pei
cent applicant got SO. 1875 gair
which added to cost gave SIC
9375. what goods must be sold
for. The selling price is then
equal to the marked price less &c
per cent, or 80 per cent of it.
Applicant then divided selling
price by 80 per cent, which gave
$13.67 plus as the marked price.
Same problem worked by
fractions would run thus: Cost
1915. plus IA of it is $40. 1875,
the selling price, which is 4-5 of
marked price. If it is 4-5, IA of
it, or S2.7343 plus, would be 1 S,
5 times which, OF $13.67 plus, is
the marked price. -Editor).
Eighth.
Lost 5000, gained 3-4 as much as
he had left, then had 1-2 as much
as at first. How much at first?
"A left, 3.4 gain to which
makes IA, equals 1-2 as much as
ne had at first, which was 5000
plus Al of what he had left
IA equals 1-2(s6CO plus 4.4)
IA equals $500 plus "a of
what he had left.
"A less "a is sd, equals $500,
$50 would be IL, and $24O would
be what he had left, This add.
ed to what was lost gives $84C
that he had at first.
Ninth.
The amount of the principal at
6 per cent fora certain time is
$3.50, and at 10 per cent for the
same time is $500. Find prin.
The difference in amounts,
$120, must be interest for the
amount at per Cent, the differ
ence between 6 and 10 per cent
If S12O is 4 per for the time,
then $50 is ] per cent, and $3.50
is 6 per cent for the time, which
would leave 5000 Oas the principal;
and the time is 5 years.
Tenth
If 8 men can build a wall 12C
feet long, IL feet thick and
teet high in 9 days, working 9
hours a day, how many days will
it take 20 men to build wall 200
feet long, 2 feet thick and feet
high, working 10 hours day?
,, Omen 9 days 8 hours, 576.
120long 2 high 1 1-2 thick, $50.
20 men x days 10 hours, 200.
500 long 5 high 2 thick, 1000.
Then 576 800 :: 200 1000.
Applicant divided the product
of the extremes by the product
of the means which gave 1e
days as the answer.
There were thirteen problems,
applicant to work any ten Of
them. The other three will be
given next week.
1t was huge undertaking
the mechanical part of the Her
aid, with two small boys who hat
never been inside printing
office before. We could have
proceeded to turn out any kint
of old paper and made our par
of it easier; but the editor pre-
ferred to give the public news
paper, and Notwithstanding
that, in order to do SO, we have
been few times late in getting
out the paper, we believe thu
public appreciates the circum
stances and the efforts put fortl
as we know it has appreciated
the paper for it's own self. W.
believe though that we have now
arrived at that point when W.
ca1 announce that, unless some
thing Unforeseen intervenes, WI
will hereafter be out prompt!
on time, and at the same tint
keep on making the paper bette
and better.
The Sentinel up and declare.
that it has been calling attention
to feterita grown in this county
for a long time, and is puzzlet
because everybody didn't know
about it. If editor Jones want

he should have sent a few lines t.
