Solution

Change in percentage = 3.33+5=8.33%
change in price = Rs 65
The percentage if he sells for Rs 65 is = 8.33%
The percentage if sells for Rs 1 $= \frac{8.33}{65}$
The percentage if he sells for Rs 936 = $\frac{8.33}{65} \times 936$
$= \frac{833}{6500} \times 936$
$= 120$ %
$∴$ Profit = 120-100=20%
