Problem Analysis

To solve this problem, we need to find out how many pairs of shoes are left after the day's sales. We are given that 1200 pairs of shoes arrived at the department store. Before lunch, 2/5 of the total shoes were sold, and after lunch, 3/4 of the remaining shoes were sold. We need to calculate the number of shoes left after the day's sales.

Calculation

Let's calculate the number of shoes sold before lunch: - 2/5 of 1200 pairs = (2/5) * 1200 = 480 pairs

Now, let's calculate the number of shoes remaining after lunch: - Remaining shoes = Total shoes - Shoes sold before lunch = 1200 - 480 = 720 pairs

Next, let's calculate the number of shoes sold after lunch: - 3/4 of the remaining shoes = (3/4) * 720 = 540 pairs

Finally, let's calculate the number of shoes left after the day's sales: - Shoes left = Remaining shoes - Shoes sold after lunch = 720 - 540 = 180 pairs

Answer

After the day's sales, there are 180 pairs of shoes left in the department store.
