**Approach:** Assume cost price as $100.

Let the cost price of the goods to be $ 100.

The merchant marks his goods up by 50%.

Therefore, his marked price = cost price + mark up.

Marked price = $100 + 50% of $100 = 100 + 50 = $150.

The merchant offers a discount of 20% on the marked price.

Discount offered = 20% of 150 = $30.

Therefore, the goods are finally sold at $150 − $30 = $ 120.

Cost price is $100 and final selling price is $120.

Therefore, profit made = $20 on the cost price of $ 100.

Hence, % profit = \\frac{\text{profit}}{\text{cost price}}) × 100 = \\frac{20}{100}) × 100 = 20%.

**Merchant made a profit of 20%**
