Question

Find the profit per cent or loss per cent made in each of the following cases, when :
by selling 20 identical articles, a shopkeeper gains equal to C.P. of 5 articles.

• A. Loss $=12$%
• B. Loss $=30$%
• C. Profit $=22$%
• D. Profit $=25$%

Answer 1

Answer: (D)

Profit $=25$%

Let Cost price of $1$ article $=Rsx$
=> And Cost price of $20$ articles $=Rs20x$
Given, Gain on selling $20$ articles $=$ Cost price of $5$ articles $=Rs5x$
Now, Profit % $=\frac{Profit}{C.P.}\times 100=\frac{5x}{20x}\times 100=\frac{1}{4}\times 100=25$ %
