Loss

A bookstore purchased from a publisher the biography of a well-known politician for R15 per copy, but sales have been very poor. The manager has decided to mark the copies down to R12 each to make a quick sale. Calculate the loss on each book as a percentage of the selling price.

Result

p =  20 %

Solution:

p=100 151215=20=20%p=100 \cdot \ \dfrac{ 15-12 }{ 15 }=20=20 \%
