A trader buys coffee for 1200 and sells it 1500 For each bag of he earns a profit 50 How many bags did have?

Profit per bag = Selling price - Cost price

Profit per bag = 1500 - 1200

Profit per bag = 300

Step 2: Calculate the number of bags sold

Let the number of bags sold be x.

Then, Total profit = Profit per bag * Number of bags sold

Total profit = 300x

Step 3: Equate the total profit to the given profit

We know that the trader earns a total profit of 50.

Therefore, 300x = 50

Step 4: Solve for x

Dividing both sides by 300, we get

x = 50/300

x = 1/6

Step 5: Interpret the result

The trader sold 1/6 of a bag of coffee. Since we cannot sell a fraction of a bag, we can conclude that the trader did not sell any bags.
