The mass of each bag of flour is 2 kg.
What is mass?
In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. In the International System of Units, a kilogram is a unit of mass (SI).
How to solve this problem?
Given that the mass of each bag of rice is 1.2 kg. We can see that there are 5 and 3 bags containing rice and flour respectively. First, we have to calculate the total weight of the right side of the weight machine. Then we equate it with the total weight of the left side of the weight machine.
Let, the mass of each bag of flour be y kg.
Now,
Weight of the right side = Weight of the left side
i.e. number of rice bags × mass of rice bags = no. of flour bags × mass of flour bags
i.e. 5 × 1.2 = 3 × y
i.e. 3y = 6.0
i.e. y =6/3=2
So, the mass of each bag of flour is 2 kg.
