Question

cost price of a book is rs340
profit percentage = 10%
Calculate the SP ?​

Answer 1

★ Answer -

• The selling price of the book is Rs 374.

★ To find -

• The selling price of the book.

★ Step-by-step explanation -

• Here, the cost price and profit percentage of a book are given to us. We have to find its SP.

We know that -

$\bigstar \: \underline{ \boxed{\sf SP = \dfrac{CP \: (100 + Profit \: \%)}{100}}}$

Substituting the given values in this formula -

$\longmapsto \bf SP = \dfrac{340 \: (100 + 10)}{100}$

$\longmapsto \bf SP = \dfrac{340 \: (100 + 10)}{100}$

$\longmapsto \bf SP = \dfrac{340 \: (110)}{100}$

$\longmapsto \bf SP = \dfrac{340 \times 110}{100}$

$\longmapsto \bf SP = \cancel{\dfrac{37400}{100}}$

$\longmapsto \bf SP = Rs \: 374$

Hence -

• The selling price of the book is Rs 374.
