Question

janata stationery bought 8 book for rs 1280 at 20% discount on marked price from a book dealer what is mp of each book​

Answer 1

To find the marked price (MP) of each book, divide the selling price by (1 - discount %).

Step-by-step explanation:

To find the marked price (MP) of each book, we can use the formula:

MP = (Selling Price)/(1 - Discount %)

Here, the selling price (SP) is given as Rs. 1280 and the discount is 20%. Let's plug them into the formula:

MP = 1280/(1 - 0.20)

MP = 1280/0.80

MP = 1600

Therefore, the marked price of each book is Rs. 1600.

Answer 2

Rs 200

Step-by-step explanation:

If Janata Stationery bought 8 books for Rs 1280 at a 20% discount on the marked price, we can use the following formula:

`\sf \textsf{Selling Price (SP)} = \textsf{Marked Price (MP)} - Discount \% * \textsf{Marked Price}`

In this case, the Selling Price is Rs 1280, the discount percentage is 20% = 0.2, and the number of books is 8.

Substitute the known value and solbe for MP.

`\sf 1280 = \textsf{MP} - 0.2 * MP`

`\sf 1280 = 0.8 * \textsf{MP}`

`\sf \textsf{MP} = (1280)/(0.8)`

`\sf \textsf{MP} = 1600`

So, the marked price of 8 book is Rs 1600.

Now

The marked price of each book :

`\sf = (Rs 1600)/(8) = Rs 200`

Therefore,the marked price of each book is Rs 200.
