Answers
Answer:
Here you go ..............
Step-by-step explanation:
The Cost price of 20 books = selling price of 18 books
So cost price of one book = 9/10 selling price of one book
Selling price = 10/9 Cost price
Profit is obtained because cost price is less than selling price
Profit = SP - CP = 10/9CP - CP = 1/9 CP
Profit percent = profit / CP x 100
= [{(1/9) CP }/ CP] x 100
= 1/9 x 100 = 100/9
= 11.11%

Answer:
100%
Step-by-step explanation:
Let the cost price be 100
Cost price of 20 books = 20×100 = 2000
Selling price of 18 books = 2000
Selling price of 1 book = 2000/18
Profit = SP - CP
= 2000/18 - 100
= 2000-100/18
= 200/18
Profit % = Profit/CP × 100
= 200/18/100 × 100
= 200/18
= 100%
