Question

By selling 36 oranges a vendor suffers a loss equal to the selling price of 4 oranges. Find the loss pdrcentage.

Answer 1

let the S.P. of one orange be x .

therefore,
SP of 36 oranges = 36x
given-
loss = SP of 4 oranges = 4x
then,
CP = SP+Loss
=36x+4x
=40x
Loss%=
$\frac{loss}{cp} \times 100$
= (photo)
=10%

ANSWER- LOSS%=10%

$\red{ \textsf{Loss percentage = \orange{10 \% }}}$

$\huge \purple{ \underline{ \boxed{ \red{ \mathbb{EXPLANATION : }}}}}$

$\red{ \textsf{Let x be the price of an orange . }}$

$\green{ \mathbb{ACCORDING \: TO \: QUESTION :}}$

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

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

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

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

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