Question

A person sells two articles, each for Rs 1040. He incurs 20% loss on the first and 10% loss on the second. Find out overall percentage loss.

• A. $12\frac{5}{17}\%$
  
• B. $15\frac{5}{17}\%$
  
• C. $13\frac{3}{4}\%$
  
• D. $14\frac{3}{4}\%$
  
• E. None of these

Answer 1

The correct option is B $15\frac{5}{17}\%$


We have, x =-20 and y =-10.
$\therefore$ Overall gain/loss
$=\left[\frac{100(-20-10)+2x-20x-10}{(100-20)+(100-10)}\right]\%=-\frac{2600}{170}\%=-15\frac{5}{17}\%$
