Step 1: Calculate the price at which Manish bought the bicycle.
Discounted Price:
\[ 10000 - \frac{33.33}{100} \times 10000 = 10000 - 3333.33 = 6666.67 \]
Step 2: Manish sold the bicycle for ₹10,000. The profit earned is:
\[ 10000 - 6666.67 = 3333.33 \]
Step 3: Calculate the percentage of profit.
\[ \frac{3333.33}{6666.67} \times 100 = 50\% \]
Conclusion: The profit percentage is 50%.
