Question

A man sold his bicycle for Rs. 405405 losing one-tenth of its cost price. Find the loss percent.

• A. $12$%
• B. $10$%
• C. $18$%
• D. $16$%

Answer 1

The correct option is B $10$%

Selling Price of bicycle $=$ Rs. $405$

Let Cost Price be $x$

As he loses $\frac{1}{10}$th of its cost price upon selling, Selling Price $=x-\frac{x}{10}$

$\Rightarrow$ $405=\frac{9x}{10}$

$\Rightarrow$ $x=450$

Loss $=\frac{x}{10}$

$=$ Rs. $45$

Loss $\%=\frac{loss}{x}\times 100$

$=10\%$
