Answer 2

Answer:

Her profit/loss percent is  10%.

Step-by-step explanation:

Divya purchased 11 books for 10 rupees.

Hence, Divya spent a total of (11×10) rupees = 110 rupees in buying the books.

Divya sold all books for 11.

Hence, Divya got a total of (11×11) rupees = 121 rupees in selling the books.

Divya's profit= (121-110) rupees = 11 rupees.

Divya's profit percent = (11×100)/110 % = 10%

∴Her profit/loss percent is  10%.
