Question

if the cost price of 10 Notebooks is equal to the selling price of 15 notebooks find the loss peecent

Answer 1

Answer:

33.33%

Step-by-step explanation:

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

= $\frac{x-y}{x}$×100

= $\frac{x-\frac{2x}{3} }{x}$×100

= 100/3 = 33.33
