Answer 1

1%

Explanation:

Money spent by the stationer :

• 100 books x 80 rupees
• 8000 rupees

Money earned (after donation and sales) :

• Donated 10 books = 0 rupees
• Sold rest at 88 rupees per book
• 90 books x 88 rupees
• 7920 rupees

Here, the money spent is more than the money earned. Hence, we have to find the loss percentage.

• Loss % = New - Old / Old
• Loss % = 7920 - 8000 / 8000
• Loss % = -80/8000
• Loss % = -1/100

The loss percentage is 1%
