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%
