Question

a book which cost 300 naira was sold for 240naira.what was the loss percentage?​

Answer 1

Answer:

20%

Step-by-step explanation:

Since the original price of the book is 300 naira...

100% = 300 naira

1% = 300 ÷ 100 = 3 naira

240 ÷ 3 = 80

Since 80% is the percentage of the price after the loss..

100 - 80 = 20%
