A man bought a cycle for Rs.450 and sold for Rs.405. find the loss percent.

\par Loss = 450 - 405 = 45                                   

\par Loss %  = \frac{45}{450} \times 100 = 10                                 \par \lbrack loss % = \frac{loss}{C.P.} \times 100\rbrack $

\par \therefore$ loss % = 10
