The total mass of 4 bags of rice flour and 6 bags of flour is 190 kg. Each bag of rice flour has a mass of 13 kg.
- What is the total mass of 4 bags of rice flour?
- What is the total mass of 6 bags of flour?
- If each bag of flour has the same mass, what is the mass of 1 bag of flour?
(a)
Let the mass of 1 bag of rice flour and flour be R and F respectively.
Let 1 bag of rice flour be 1 R.
Let 1 bag of flour be 1 F.
4 R + 6 F = 190
1 R = 13
Mass of 4 bags of rice flour
= 4 x 13
= 52 kg
(b)
Mass of 6 bags of flour
= 190 - 52
= 138 kg
(c)
Mass of 1 bag of flour
= 138 ÷ 6
= 23 kg
Answer(s): (a) 52 kg; (b) 138 kg; (c) 23 kg
