Answer 1

Answer:

find the S.p of one book

Answer 2

Given data :-

• Renu bought ten copies of a book for Rs 450.
• Renu spent Rs 20 on the cartage and then sold them at profit of 15 %.

Solution :-

According to given :

→ cost price of 10 copies = Rs 450

→ spent money on the cartage = Rs 20

Hence,

→ total cost = Rs {450 + 20}

→ total cost = Rs 470

→ profit percentage on selling 10 copies = 15 %

Now, we use formula of profit % :

→ profit % = {profit × 100}/total cost

→ 15 = {profit × 100}/470

→ 15 × 470 = profit × 100

→ 7050 = profit × 100 i.e.

→ profit = 7050/100

→ profit = Rs 70.50

To find selling price of 10 copies :

→ selling price = total cost + profit

→ selling price = 470 + 70.50

→ selling price = Rs 540.5

Now, to find selling price of one book :

→ selling price of one book

= {selling price of 10 copies}/10

→ selling price of one book

= 540.5/10

→ selling price of one book

= Rs 54.05

Hence, the selling price of one book is Rs 54.05
