What did he get?
Solution:-
Total books are purchased by Ravi = 10
The cost of 10 books = Rs. 60
The cost of each book = Rs. 60/10 = Rs. 6
Number of books are gives as free = 1
Total number of books with Ravi
= 10+1 = 11
Selling Price of each book
= 5% less than the Price printed on the book
=> 6 - 5% of 6
=> 6 - (5/100)×6
=>6 - (1/20)×6
=> 6-(6/20)
=> 6-(3/10)
=> (60-3)/10
=> 57/10
=> 5.7
The cost of each book sold by Ravi = Rs. 5.70
Total cost of 11 books
=> 11×Rs. 5.70
=> Rs.62.70
He bought 10 books for Rs. 60
He sold 11 books for Rs. 62.70
62.70 > 60
He got profit
The profit = Rs. 62.70 - Rs. 60
