Question

a bookseller sold 200 copies of a book at a loss of 5% if each copy costs him Rs 40,find the selling price of the book
.​

Answer 1

Answer:-

Given:

Number of copies of books = 200

CP of each book = Rs. 40

⟶ CP of 200 books = 40 * 200 = Rs. 8000

Loss% = 5%

We know that,

SP = [ 100 - loss% / 100 ] * CP

⟶ SP (200 copies) = [ 100 - 5 ] * 8000/100

⟶ SP (200 copies) = 95 * 80

⟶ SP (200 copies) = Rs. 7600

Now,

SP of 1 copy of book = 7600/200

⟶ SP of 1 copy of book = Rs. 38

∴ The SP of the book is Rs. 38.

Additional Information:-

• Profit = SP - CP

• Loss = CP - SP

• Profit% = (Profit/CP) * 100

• Loss% = (Loss/CP) * 100

• SP = [ 100 - loss% ] * CP /100

• SP = [ 100 + gain% ] * CP / 100

• CP = 100 * SP/ 100 - loss%

• CP = 100 * SP / 100 + gain%

Answer 2

Step-by-step explanation:

Given : -

• No. of copies sold = 200
• Loss = 5%

C.P of each copy = Rs.40

Total C.P = No. of copies x C.P of each copy

               =  R.s(200 x 40)

= R.s 8000

➻ S.P = R.s(95/100 x 8000)

➻ S.P = 95 × 80

➻ S.P = 7600 R.s

the selling price of the book

Sp / number of copy

➻ = 7600 / 200

➻ = 38 R.s
