Question

a vendor loses the price of four oranges on selling thirty six oranges. his loss percent is ?

Answer 1

Let the Sp of 1 orange = ₹1
Sp of 36 oranges= 36×1 = ₹36
Loss = Sp of 4 orange
= 4×1 = ₹4
Cp of orange = Sp + Loss
=36+4
=₹40
Loss = Cp - Sp
=₹40 - ₹36
=₹4
Loss % = loss/cp×100
= 4/40×100
10%

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

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

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

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

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

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

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