Question

Q1. A book seller sold 200 copies of books at a profile of 20% . If a book costs him Rs 70,find the total SP of the books.

Answer 1

Answer:

Given -

• Total number of copies = 200
• Profit = 20%
• Cost = Rs. 70
• Cost of 200 copies = 200 × 70 = 14000

To find -

• Total SP of the books.

Solution -

As we know that the profit is 20%. So,

Profit = 14000 × 20 / 100

→ 2, 800

So, total SP is -

→ 14000 + 2800

→ 16,800

Answer 2

Answer:

Given:

A book seller sold 200 copies of books at a profit of 20%.

Find:

• If a book costs him Rs 70, find the total SP of the books.

Remember:

• 200 copies = 200 (70) = 14000

Using formula:

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

Calculations:

⇢ $\sf{\dfrac{14000 \times 20}{100}}$

⇢ ${\sf{\underline{\boxed{\pink{\sf{2800 }}}}}}$

Using the above value, we get:

⇢ $\sf{14000 + 2800}$

⇢ ${\sf{\underline{\boxed{\pink{\sf{16800}}}}}}$

Therefore, 16800 is total selling price of the books.
