**Question:**

A dealer buys a wristwatch for Rs 225 and spends Rs 15 on its repairs. If he sells the same for Rs 300, find his profit percent.

**Solution:**

A dealer buys a wrist watch for Rs. 225

Money spent on repair ing the watch $=$ Rs. 15

Therefore, C. $\mathrm{P}=$ Rs. $(225+15)=$ Rs. 240

S. $\mathrm{P}=$ Rs. 300

Profit $=\mathrm{SP}-\mathrm{CP}$

$=$ Rs. $(300-240)$

$=$ Rs. 60

Profit $\%=\frac{\text { Profit }}{\text { C.P }} \times 100$

$=\frac{60}{240} \times 100$

$=25 \%$
