1. Answer:

   33.33%

   Let cost of one notebook is x and selling price of one notebook is y. Then according to the condition of the question,

   10x=15y

   y = 2x/3

   So the loss is x-y per notebook.

   The percentage loss is given by

   percentage loss = loss/cost × 100

   = \frac{x-y}{x}

   x

   x−y

   ×100

   = \frac{x-\frac{2x}{3} }{x}

   x

   x−

   3

   2x

   ×100

   = 100/3 = 33.33
