Question

A bookseller purchased 11 books for ₹10 and sold all the books at the rate of 10 books for ₹11 Find the profit percent
​

Answer 1

Answer:

21%

Step-by-step explanation:

Cp of 11 book=₹10

SP of 10 books= ₹11

CP of each book = Rs. 10/11

SP of each book = Rs. 11/10

Profit = Rs. (11/10–10/11)= Rs. 21/110

Profit % = (21/110)×100/(10)11= (21×100×11)/(110×10)= 21%
