Question

If the selling price of a book is 3/5 of its cost price, find the loss percent​

Answer 1

The loss percentage is 40%

GIVEN

Selling price of book is 3/5 of its cost price.

TO FIND

The loss percentage of the book.

SOLUTION

We can simply solve the above problem as follows;

Let the cost price of the book be,Rs X

Selling price of the book =

$\frac{3}{5}x$

Loss on the book =

$= x - \frac{3}{5} x$

$= \frac{5x - 3x}{5}$

We know that,

Loss% = (Loss/C.P) × 100

Therefore,

$= \frac{ \frac{2x}{5} }{x} \times 100$

$= \frac{2x \times 1}{5 \times x} \times 100$

= 40%

Hence, The loss percentage is 40%

Answer 2

Answer:

If the selling price of a book is 3/5 of its cost price, find the loss percent​.

Step-by-step explanation:

• Selling  price of an item or service is the price payable by the customers to avail that goods or services. It is inclusive of profit earned or loss suffered by the seller.
• Hence it can be said that SELLING PRICE=COST PRICE (+)(-)PROFIT/LOSS.
• Cost price of an item means the total of direct and indirect cost incurred to bring an item to its present salable condition on which profit can be earned.
• Hence COST PRICE= SELLING PRICE (-)(+) PROFIT/LOSS.
• Selling price is denoted by SP and cost price is denoted by CP.
• In this question SP of a book=$\frac{3}{5}$ of CP.
• It means selling price is lower than the cost price.
• Hence loss =CP-SP.
• ⇒$Loss= CP-\frac{3}{5} CP$
• $=\frac{2}{5} =40%.$%
• so total loss is 40%.
