Question

Shouvik sells a book at 10% discount whose marked price is
₹ 350 , then find the selling price of the book.

• A. 315

Answer 1

The correct option is A 315
Given,
Regular cost = ₹ 350
Discount is 10 % of regular price. So,

$\text{Discount}=\text{regular price}\times \frac{10}{100}$
$\text{Discount}=₹350\times \frac{10}{100}$
$\text{Discount}=₹35$

Now,
Selling price = Regular price - discount
Selling price = ₹ 350 - ₹ 35
Selling price = ₹ 315

[Alternate way]

Given,
Discount percent = 10%
Marked price = ₹ 350

Now, we know that
Discount % $=\frac{\text{Discount}}{\text{Marked price}}\times 100$

From this, the discount can be calculated as
$\text{Discount}=\frac{\text{Discount \%}}{100}\times \text{Marked price}$
$\text{Discount}=₹350\times \frac{10}{100}$
$\text{Discount}=₹35$
Now,
Selling price = Marked price - discount
Selling price = ₹ 350 - ₹ 35
Selling price = ₹ 315
