Hi!

what you do is you move all the numbers on one side of the equal sign and the variable on the other side, when you move the numbers the switch signs

so it will look like

-2n=2-4

-2n=-2

drop the minus

2n = 2

n =1

If 24 bags of sugar with equal weight weigh 21 kg, how many bags of sugar would weigh 122kg?

aleksandrvk [35]

Answer:

24 bags = 21 kg

1.142 bag = 1 kg

About 139 bags = 122 kg

You start off with 24 bags that equal the same amount as 21 kg. You need to find out how many bags of sugar equal the same amount as 122 kg. The first line is a ratio and to find your answer you need to figure out what is 1 kilogram equal to in the amount of bags. You divide both sides by 21 leaving 1.142 bag equal to 1 kilogram. In order to find 122 kilograms, you have to multiply both sides by 122 kilograms which would give you about 139 bags = 122 kilograms.

Your final answer: 139 bags

I hope this helped!

A pair of shoes which costs Rs 320 was sold at a loss of 5%what was the selling price if it is sold at profit of 20%find the gai

taurus [48]

Answer:

The Sell Price of the shoe at 5% loss is Rs 304.

The Sell Price of the shoe at 20% profit is Rs 384.

The Total Gain Percent is 12.5% when shoes are sold at Rs.360.

Step-by-step explanation:

Given,

Cost Price(C.P.) of shoe = Rs 320

Case 1.

Loss = 5%

C.P. = Rs 320

Here loss percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100-loss\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100-5)}{100}\\\\S.P. =\frac{320\times 95}{100} =\frac{30400}{100} =Rs\ 304$

The Sell Price of the shoe at 5% loss is Rs 304.

Case 2.

C.P. = Rs 320

Profit = 20%

Here profit percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100+profit\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100+20)}{100}\\\\S.P.=\frac{320\times 120}{100}=\frac{38400}{100}=Rs\ 384$

The Sell Price of the shoe at 20% profit is Rs 384.

Case 3.

C.P. = Rs 320

S.P. = Rs 360

Now we need to find the gain percent.

First we will find the gain.

Gain is the difference of S.P with C.P.

Gain = $360-320 = 40$

Now Gain Percent can be calculated by dividing gain with the cost price and then multiplying it with 100

Gain Percent = $\frac{40}{320}\times 100 = 12.5\%$

Hence The Total Gain Percent is 12.5% when shoes are sold at Rs.360.
