Solution
\[\text { A dealer buys a wrist watch for Rs } . 225\]
\[\text { Money spent on repairing the watch = Rs } . 15\]
\[\text { Therefore, C . P = Rs } . (225 + 15) = Rs . 240\]
\[\text { S . P = Rs . } 300\]
\[\text { Profit = SP - CP }\]
\[ = Rs . (300 - 240)\]
\[ = Rs . 60\]
\[\text { Profit % }= \frac{\text { Profit }}{C . P} \times 100\]
\[ = \frac{60}{240} \times 100\]
\[ = 25\]%
