The total mass of 5 packets of sugar and 4 packets of curry powder is 169 kg. Each packet of sugar has a mass of 17 kg.
- What is the total mass of 5 packets of sugar?
- What is the total mass of 4 packets of curry powder?
- If each bag of curry powder has the same mass, what is the mass of 1 packet of curry powder?
(a)
Let the mass of 1 packet of sugar and curry powder be S and C respectively.
Let 1 packet of sugar be 1 S.
Let 1 packet of curry powder be 1 C.
5 S + 4 C = 169
1 S = 17
Mass of 5 packets of sugar
= 5 x 17
= 85 kg
(b)
Mass of 4 packets of curry powder
= 169 - 85
= 84 kg
(c)
Mass of 1 packet of curry powder
= 84 ÷ 4
= 21 kg
Answer(s): (a) 85 kg; (b) 84 kg; (c) 21 kg
