Let the cost price of 10 books be 100. So selling price of 8 books=100. So. cost price of 1 book= 100/10=10. And SP of 1 book= 100/8=25/2. Cost price of 8 books= 10×8=80. gain=Sp of 8 books-Cp of 8 books= 100-80=20. gain%= 20/100×100=20%

Answer:

20% loss

Step-by-step explanation:

Let the selling price of 10 books be 100

so, cost price of 8 books = 100

selling price of 1 books = 100/10=10

Cost price of 1 books =100/8 =25/2

Selling price of 8 books = 10×8 = 80

since, C.P > S.P , there is loss

Loss = C.P - S.P

= 100- 80

= 20

Loss% = Loss/ C.P ×100

= 20/100×100

= 20%
