A container packed with 2 packets of curry powder weighs 4.63 kg. The same container when packed with 12 such packets of curry powder weighs 23.83 kg.
- Find the mass of 2 packets of curry powder in kg.
- Find the mass of the empty container in kg.
(a)
Let the mass of 1 container be 1 C.
Let the mass of 1 bag of curry powder be 1 B.
1 C + 2 B = 4.63 --- (1)
1 C + 12 B = 23.83 --- (2)
(2) - (1)
10 B = 23.83 - 4.63
10 B = 19.2
1 B = 19.2 ÷ 10 = 1.92
Mass of 2 packets of curry powder
= 2 x 1.92
= 3.84 kg
(b)
Mass of the empty container
= 4.63 - 3.84
= 0.79 kg
Answer(s): (a) 3.84 kg; (b) 0.79 kg
