Question 8
Amina buys a book for Rs 275 and sells it at a loss $15\%$. How much does she sell it for?

Given that
Amina bought a book for Rs 275.
So the Cost price, CP = Rs 275.

$\text{Loss}\%=15\%$

$\text{Loss}=15\%\text{of}275$

$\text{Loss}=\frac{15}{100}\times 275$

$\text{Loss}=\frac{4125}{100}$

$\text{Loss}=41.25$

$\text{Selling price}=\text{Cost price - Loss}$

$\text{Selling price}=275-41.25$

$\text{Selling price}=\text{Rs.}233.75$

Hence she sold it at Rs 233.75.
