Answer 2

Calculation of the Amount of Flour Sold

To calculate the amount of flour that was sold, we need to subtract the weight of the remaining flour from the initial weight of 40 kg.

Given that there were 9 packets of flour left, with each packet weighing 2 kg, we can calculate the weight of the remaining flour as follows:

Weight of remaining flour = Number of packets left * Weight per packet

Weight of remaining flour = 9 packets * 2 kg/packet = 18 kg

To find the weight of the flour that was sold, we subtract the weight of the remaining flour from the initial weight:

Weight of flour sold = Initial weight - Weight of remaining flour

Weight of flour sold = 40 kg - 18 kg = 22 kg

Therefore, 22 kilograms of flour were sold.
