Problem Analysis

To solve this problem, we need to find out how many kilograms of flour were sold on the third day. We are given that a total of 144 tons of flour were delivered to the store. On the first day, 7/16 of the total flour was sold, and on the second day, another 7/16 was sold. The remaining flour was sold on the third day. We need to determine the weight of the flour sold on the third day.

Solution

To find the weight of the flour sold on the third day, we first need to calculate the weight of the flour sold on the first two days. Then, we can subtract this amount from the total weight of the flour to find the weight sold on the third day.

Let's calculate the weight of the flour sold on the first two days: - On the first day, 7/16 of the total flour was sold. So, the weight of the flour sold on the first day is (7/16) * 144 tons. - On the second day, another 7/16 of the total flour was sold. So, the weight of the flour sold on the second day is also (7/16) * 144 tons.

Now, let's calculate the weight of the flour sold on the third day: - To find the weight of the flour sold on the third day, we need to subtract the weight of the flour sold on the first two days from the total weight of the flour. The total weight of the flour is 144 tons.

Let's calculate the weight of the flour sold on the first two days: - Weight of flour sold on the first day: (7/16) * 144 tons = 7 * 9 tons = 63 tons - Weight of flour sold on the second day: (7/16) * 144 tons = 7 * 9 tons = 63 tons

Now, let's calculate the weight of the flour sold on the third day: - Weight of flour sold on the third day: Total weight of flour - Weight of flour sold on the first two days = 144 tons - (63 tons + 63 tons) = 144 tons - 126 tons = 18 tons

Therefore, 18 tons of flour were sold on the third day.

Answer

18 tons of flour were sold on the third day.
