→ Number of copies of a book = 300 .

To find :-

→ The selling price of 300 books .

Solution :-

According to question,

→ Cost price of 1 copy = ₹48 .

→ Cost price of 300 copies = 48 × 300 = 14400 .

∵ Selling price of 300 copies = ( 15/100 × 14400 ) + 14400.

= 2160 + 14400.

= 16560 .

Total selling price of 300 copies of books = ₹16560 .

Answer 2

Answer:

Given:

• A book seller sold 300 copies of books at a profit of 30%.

Find:

• If a book costs him Rs 15, find the total SP of the books.

Remember:

• 300 copies = 300 (15) = 4500

Using formula:

⇢ $\tiny{\sf{\underline{\boxed{\blue{\sf{ Profit = \dfrac{Cost \: price \times Profit \: percentage}{100} }}}}}}$

Calculations:

⇢ $\sf{\dfrac{4500 \times 30}{100}}$

⇢ ${\sf{\underline{\boxed{\pink{\sf{1350 }}}}}}$

Using the above value, we get:

⇢ $\sf{4500 + 1350 }$

⇢ ${\sf{\underline{\boxed{\pink{\sf{5850}}}}}}$

Therefore, 16800 is total selling price of the books.
