Show Answer
Answer:
Correct Answer: A
Solution:
- Let the cost price $ =Rs.,x $
$ \therefore $ Marked price $ =x+20%\text{ of},x $ $ =x+\frac{x}{5}=Rs.\frac{6x}{5} $ Selling Price $ =Rs.( \frac{6x}{5}-5%of\frac{6x}{5} ) $ $ =Rs.\frac{6x}{5}( 1-\frac{1}{20} ) $ $ =Rs.\frac{6x}{5}\times \frac{19}{20} $ $ =Rs.\frac{57x}{50} $ Profit $ =Rs.\frac{57x}{50}-x=Rs.\frac{7x}{50} $
$ \therefore $ Profit per cent $ =\frac{50}{x}\times 100=14% $
