Question

A man sold his bicycle for Rs. $405$ losing one-tenth of its cost price. Find its cost price.

• A. Rs. $250$
  
• B. Rs. $320$
  
• C. Rs. $400$
  
• D. Rs. $450$

Answer 1

Answer: (D)

Rs. $450$

Given: S.P. $=405$ Rs.
Loss $=\frac{1}{10}\times C.P.$
$\Rightarrow$ C.P. $-$ S.P. $=\frac{1}{10}\times$ C.P.
$\Rightarrow \frac{9}{10}\times$ C.P. $=405$ Rs.
$\Rightarrow$ C.P. $=450$ Rs.
