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 %

A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles. HINT [See Example 7.

kirill115 [55]

Answer:

There are 12 sets of four marbles include all the red ones.

Step-by-step explanation:

Given : A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles.

To find : How many sets of four marbles include all the red ones?

Solution :

Number of red marbles = 3

Number of green marbles = 2

Number of lavender marbles = 1

Number of yellow marbles = 4

Number of orange marbles = 5

We have to form sets of four marbles include all the red ones,

For position of getting red ones we have three red marbles i.e. $^3C_3$

For the fourth one we have 12 choices i.e. $^{12}C_1$

Total sets of four marbles include all the red ones is

$=^3C_3\times ^{12}C_1$

$=1\times 12$

$=12$

Therefore, There are 12 sets of four marbles include all the red ones.

Mrs. Bogaczyk got bored and decided to go on an Amazon spending spree! She bought 3 pairs of flip flops for $14.95 each, a sundr

Dovator [93]

Step-by-step explanation:

3 pairs of flip flops = 14.95 x 3 = 44.85

Total amount spent = 44.85 + 21.50 + 9.99 + 15. 44 = 91.78

After adding tax = 91.78 + 7.34 = 99.12

Mrs B spent 99.12 altogether

Budget = 100

Then money left = 100 - 99.12 = 0.88

1. If a = -1 , the value of3a + 1 is

erastovalidia [21]

Answer:

$f(a) = 3a + 1 \\ Now,\: a = - 1 \\ f( - 1) = 3( - 1) + 1 \\ f( - 1) = - 3 + 1 \\ \boxed{ f( - 1) = - 2}$

Therefore, -2 is the right answer.
