Answer 2

$\huge\red{Question:}$

An item was sold for Rs.440 at a loss of 10%, what was its cost price?

$\huge\green{Solution ->}$

Given,

S.P = Rs 440

L = 10 %

Let the cost price be x, then,

$loss = ( \frac{loss}{x}) \times 100$

$loss \: = ((x \: - s.p) \div \: x) \times 100$

$\frac{5}{100} = \frac{x - 540}{x}$

$\frac{1}{20} = \frac{x - 540}{x}$

$x \: = 20(x - 540)$

$20 = 20x - 10800$

$20x - x = 10800$

$19x = 10800$

$x = 10800 \div 19$

$x = 568.42$

Thus, Cost price of the item = Rs 568.42
