If the selling price of 318 articles is equal to the cost price of 212 articles, then what is the loss percentage ?

$33 frac{2}{3} \%$

$20 \%$

$33 frac{1}{3} \%$

$40 \%$

Answer : Option C

Explanation :

C.P. of each article = Re. 1.

∴ C.P. of 318 articles = Rs. 318

S.P. of 318 articles = Rs. 212

$herefore$ Loss per cent $=left(frac{318-212}{318} ight) imes 100$

$=frac{106}{318} imes 100=frac{100}{3}=33 frac{1}{3} \%$
