Question

$630$ articles.

• A. Loss $=30\%$
• B. Profit $=30\%$
• C. Loss $=47\%$
• D. Profit $=47\%$

Answer 1

The correct option is D Profit $=47\%$

Total C.P. $=Rs0.60\times 750=Rs450$
Let $Rsx$ be the S.P. of each article.
Then, S.P. of $600$ articles $=Rs600x$
Given, for this CP and SP, Profit % $=\frac{SP-CP}{CP}\times 100=40$ %
$=>\frac{600x-450}{450}\times 100=40$
$=>600x-450=180$
$=>x=Rs\frac{630}{600}=Rs\frac{21}{20}=Rs1.05$
When, $630$ articles are sold, $S.P.=Rs1.05\times 630=Rs661.5$
So, Profit % when $630$ articles are sold, $=\frac{SP-CP}{CP}\times 100=\frac{661.5-450}{450}\times 100=47$ %
