Of the CP of 15 articles equals to the SP of 12 articles, find the gain percent. an ple 4:

Rasek [7]

Question

If the CP of 15 articles equals to the SP of 12 articles, find the gain percent.

Answer:

gain percent = 25%

Step-by-step explanation:

To solve the question given, we will follow the steps below:

gain% = $\frac{s.p - c.p}{c.p}$ × 100%

But from the question;

"CP of 15 articles equals to the SP of 12 articles", this implies that

15 c.p = 12 s.p

s.p = 15c.p / 12

s.p = $\frac{15 c.p}{12}$ = $\frac{5c.p}{4}$

s.p = $\frac{5c.p}{4}$

substitute s.p = $\frac{5c.p}{4}$ into the formula

gain% = $\frac{s.p - c.p}{c.p}$ × 100%

= $\frac{\frac{5c.p}{4} - c.p }{c.p}$ × 100%

= $\frac{\frac{5c.p - 4c.p}{4} }{c.p}$ × 100%

= $\frac{c.p}{4}$ ÷ c.p × 100%

= $\frac{c.p}{4}$ × $\frac{1}{c.p}$ × 100%

= $\frac{1}{4}$ × 100%

= 25 %

9450 = .16 N

divide by .16

9450/.16 = .16N/.16

59062.50 = N

The number is 59062.50

We want 100% of the number which is all of it

John has a rectangular-shaped field whose length is 62.5 yards and width is 45.3 yards. The area of the field is ________ square

oee [108]

Area = 2831.25 square yards

Perimeter =215.6 yards

EXPLANATION

The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.

That means, area of the rectangular field is given by the formula,

$A= l\times w$

We just have to substitute
$l=62.5$ and $w= 45.3$ into the given formula and evaluate.

This implies that;

$A= 62.5\times 45.3$

This gives the area of the rectangular-shaped field to be;

$A= 2831.25$ square yards.

Now for the perimeter, we use the formula

$P=2w +2l$

Or

$P=2(w +l)$

Substituting the values for the length and width gives,

$P=2(62.5+45.3)$

$\Rightarrow P=2(107.8)$

$\Rightarrow P=215.6$

Hence the perimeter of the rectangular shaped field is 215.6 yards.
