Mrs. Neo has two packets of flour. The ratio of the mass of flour in Packet A to the mass of flour in Packet B is 1:2. Mrs. Neo uses ⅓ of the flour in Packet A and has 800 grams left altogether. How much flour is there in Packet B?

3 answers

2/3 A = 800
A = 1200
A:B = 1:2 = 1200:2400
The Correct Answer is 600g for PACKET B
SOLUTION:

- RATIO of FLOUR A to B is 1:2
[3A/3 - 1/3] + 2A = 800 Grams
2A/3 + 2A = 800 Grams
2A/3 + 6A/3 = 800 Grams
8A/3 = 800 Grams
8A = 2400 Grams
A = 300 Grams

B = 2 (A)
B = 2 (300)
B = 600 Grams
