Question

If the credit price of 5 copies is equal to the cash price of 6 copies,what is the rate of discount?? ​

Answer 1

Answer:

16.66%

Step-by-step explanation:

Total credit price of the copied = 5 (Given)

Let the book price with credit = x.

Thus, the total credit price = 5x

Total cash price of the copies = 6 (Given)

Let the book price with cash = y.

Thus, the total cash price = 6Y.

Therefore, since they are equal -

5x = 6y, or  y = 5/6x.

Thus for each book that is bought by cash, one pays 1/6th less of the money they will spend if they used credit (also termed as discount).

Therefore, the discount is 1/6th the price of the original cost, or 16.66%.
