Question

If the selling price of 15 articles is equal to the cost price of 12 articles, then the loss percent is ___.

Answer 1

Let CP of one article be ₹1

$\therefore$ CP of 12 articles = ₹12

SP of 15 articles = ₹12

$\therefore$ SP of 1 article = $\frac{12}{15}=₹0.80$

Loss = CP - SP

= 1 - 0.80 = 0.20

$\text{Loss}\%=\frac{\text{loss}}{CP}\times 100$

= $\frac{0.20}{1}\times 100$

= 20%
