what are the main causes of underpopulation???

Answer:

let, friend club has 'x' members.

Step-by-step explanation:

According to question,

(35)^2 + (x)^2 = 1369

1225 + x^2 = 1369

x^2 = 1369 - 1225

x^2 = 144

x^2 = (12)^2

Remove square-

x = 12

Thus, friend club has 12 members and each member contributed 12 rs.

Hence, total member of both club = 35 + 12 = 47

And the amount contributed by each member of joy club is Rs. 35 and the amount of each member of friend club is Rs. 12.

5.5-;667

it is answer is it ok

Step 1:

Given data:

AB = 5.5 cm

Ap=2/3 PB.

Step 2:

Let P be a point so that AP = 2/3 PB

then AP + PB = AB

Step 3:

Substitute the value of AP in above equation.

2/3 PB PB = 5.5

Step 4:

Evaluate the step 2 data.

5/3 PB5.5

Step 5:

Find the value of PB by simplifying

PB=3.3cm

AP=2.2cm.

Answer: The Selling Price should be 49677.42 to have a profit of 10%

Step-by-step explanation:

Given that the motorcycle was sold for 42000 at a loss of 7%

We have to find the selling price so that there is a profit of 10%

Let the cost price be x

As it is sold at a loss of 7 %

[tex]loss=\frac{7}{100}x[/tex]

[tex]SP=x-\frac{7}{100}x = \frac{93}{100}x[/tex]

Given Selling Price(SP)=42000

Now,

[tex]\frac{93}{100}x = 42000\\\\ x=\frac{42000*100}{93}\\\\ x=45161.29[/tex]

So the Cost Price(CP) of the motorcycle is 45,161.29

For a profit of 10%

[tex]Profit=\frac{10}{100}*45161.29[/tex]

[tex]Profit=4516.129[/tex]

The new Selling Price of the motorcycle is = Profit + Cost Price

                                                                      = [tex]45161.29+4516.129[/tex]

                                                                      = [tex]49,677.42[/tex]

So the Selling Price should be 49,677.42 to have a profit of 10%
