Step-by-step explanation:

Full 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 consider to be sold.

Given:

The c.p. of 8 pens is same as s.p. of 10 pens.

Cp of 8 pens = Sp of 10 pens.

Let the Sp of 1 pen = ₹1

=> Sp of 10 pens = ₹10

Cp of 8 pens = ₹10

=> Cp of 1 pen = 10/8 = ₹1.25

=> Cp is more than Sp. Hence, Loss occurred.

=> Loss = Cp - Sp

=> ₹1.25 - ₹1

=> ₹0.25

Loss Percentage = (Loss/Cp)x100

Loss Percentage = (0.25/1.25)x100

Loss Percentage = 20%

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.
