The total mass of 8 bags of pepper and 3 bags of chilli powder is 188 kg. Each bag of pepper has a mass of 16 kg.
- What is the total mass of 8 bags of pepper?
- What is the total mass of 3 bags of chilli powder?
- If each bag of chilli powder has the same mass, what is the mass of 1 bag of chilli powder?
(a)
Let the mass of 1 bag of pepper and chilli powder be P and C respectively.
Let 1 bag of pepper be 1 P.
Let 1 bag of chilli powder be 1 C.
8 P + 3 C = 188
1 P = 16
Mass of 8 bags of pepper
= 8 x 16
= 128 kg
(b)
Mass of 3 bags of chilli powder
= 188 - 128
= 60 kg
(c)
Mass of 1 bag of chilli powder
= 60 ÷ 3
= 20 kg
Answer(s): (a) 128 kg; (b) 60 kg; (c) 20 kg
