The total mass of 6 packets of sugar and 4 packets of chilli powder is 176 kg. Each packet of sugar has a mass of 16 kg.
- What is the total mass of 6 packets of sugar?
- What is the total mass of 4 packets of chilli powder?
- If each bag of chilli powder has the same mass, what is the mass of 1 packet of chilli powder?
(a)
Let the mass of 1 packet of sugar and chilli powder be S and C respectively.
Let 1 packet of sugar be 1 S.
Let 1 packet of chilli powder be 1 C.
6 S + 4 C = 176
1 S = 16
Mass of 6 packets of sugar
= 6 x 16
= 96 kg
(b)
Mass of 4 packets of chilli powder
= 176 - 96
= 80 kg
(c)
Mass of 1 packet of chilli powder
= 80 ÷ 4
= 20 kg
Answer(s): (a) 96 kg; (b) 80 kg; (c) 20 kg
