Question

By selling 36 oranges, a vendor suffers a loss equal to the selling price of 4 oranges. find the loss per cent.​

Answer 1

Answer:

Step-by-step explanation:

CP of an oranges =x

CP of 36 oranges =36x

Let SP of oranges =s

∴ SP of 36 oranges =36 s

Loss =SP of 4 oranges =4 s

Loss =SP−CP

Loss =36 x−36 s

4 s=36 x−36 s

40 s=36

∴ s=9x/10

Loss %=  

CP

Loss×100

​

 

=  36 x 45×100

​

 

=  10×36x 4×9x×100

​

 

Loss%=10%

$\red { \textsf{Cost Price = 36x+4x = 40x}}$

$\red{ \textsf{Selling Price=36x}}$

$\red{\mathsf{Loss \: Percentage = \frac{Cost Price - Selling Price }{Cost Price} \times 100 }}$

$\red{\mathsf{Loss \: Percentage = \frac{4 \cancel{x}}{40 \cancel{x}} \times 100}}$

$\red{\mathsf{Loss \: Percentage = \frac{100}{10} }}$
