The total mass of 6 bags of pepper and 3 bags of curry powder is 189 kg. Each bag of pepper has a mass of 19 kg.
- What is the total mass of 6 bags of pepper?
- What is the total mass of 3 bags of curry powder?
- If each bag of curry powder has the same mass, what is the mass of 1 bag of curry powder?
(a)
Let the mass of 1 bag of pepper and curry powder be P and C respectively.
Let 1 bag of pepper be 1 P.
Let 1 bag of curry powder be 1 C.
6 P + 3 C = 189
1 P = 19
Mass of 6 bags of pepper
= 6 x 19
= 114 kg
(b)
Mass of 3 bags of curry powder
= 189 - 114
= 75 kg
(c)
Mass of 1 bag of curry powder
= 75 ÷ 3
= 25 kg
Answer(s): (a) 114 kg; (b) 75 kg; (c) 25 kg
