Question

the C.P of 8 pens is same as S.p of 10 pens .Calculate the profit or loss percent made,if all the pens bought are considered to be sold

Answer 1

Answer:

The loss percentage is given by 20%.

Step-by-step explanation:

Given : The C.P of 8 pens is same as S.p of 10 pens.

To find : Calculate the profit or loss percent made, if all the pens bought are considered to be sold ?

Solution :

Let C.P. of 8 pens = S.P. of 10 pens = Rs.100

∴  C.P. of 1 pen is $\frac{100}{8}=12.50$

And S.P. of 1 pen $\frac{100}{10}=10$

As CP>SP there is loss.

So, Loss = CP -SP  

Loss = Rs.12.5-Rs. 10

Loss = Rs.2.50

The loss percentage is given by,

$L\%=\frac{L}{CP}\times 100$

$L\%=\frac{2.50}{12.50}\times 100$

$L\%=20\%$

The loss percentage is given by 20%.

Answer 2

Answer:

Given:

cost price of 8 pens is same as selling price of ten pens calculate the profit or loss percent made if all the pens bought considered to be

sold.

Find:

if all the pens bought considered to be sold (find).

Given:

Let us assume ₹1 be cost price of one pen.If the cost price of 1 pen = ₹10 than cost of 10 be it will be ₹10.

Let ₹10 be the selling price of 10 pens.

10 / 8 = ₹1.25 = CP = 1 pen.

Formula:

→ Loss = Cp - Sp

→ ₹1.25 - ₹1

→ ₹0.25

It is loss because cost price is more than selling price.

→ (Loss / Cost price) × 100

→ (0.25 / 1.25) × 100

→ 20%

Therefore, 20% is loss.
