Answer 2

$\large\underline{\sf{Solution-}}$

Given that, By selling a chair for 1440, a shopkeeper loses 10%.

It means, we have

• Selling Price of a chair = 1440

• Loss % = 10 %

We know,

$\boxed{ \rm{ \:Cost \: Price \: = \: \frac{100 \times Selling \: Price}{100 - Loss\%} \: }}$

So, on substituting the values, we get

$\rm \: Cost \: Price \: = \: \dfrac{100 \times 1440}{100 - 10}$

$\rm \: Cost \: Price \: = \: \dfrac{100 \times 1440}{90}$

$\rm \: Cost \: Price \: = \: \dfrac{10 \times 1440}{9}$

$\rm \: Cost \: Price \: = \: 10 \times 160$

$\rm\implies \:\boxed{ \rm{ \:Cost \: Price \: = \: 1600 \: \: }}$

So, he buy chair at the cost of 1600.
