Answer 1

x is the price of 1 banana then,

Let the selling price (S.P) of 36 bananas be 36x,

The loss will be 4x,

Loss percent=loss/cost price x 100

=loss/(selling price +loss) × 100

=4x/(36x+4x) × 100

=4x/40x × 100

=1/40 × 100

=10%

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

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

$\red{ \textsf{Let x be the price of a banana . }}$

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

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

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

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

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

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

$\red{ \colorbox{yellow}{\boxed{\mathsf{Loss \: Percentage = 10\%}}}}$
