Three types of chilli powder, G, H and J come in containers of 80 g, 120 g and 240 g respectively. Containers of G, H and J are mixed together in the ratio 1 : 3 : 6 to obtain 22.56 kg of an assortment of chilli powder.

1. How many containers of G and H are used altogether?
2. Find the difference between the combined weight of all the chilli powder in containers H and containers J as compared to the chilli powder in containers G. Express the weight in kilograms.

	G	H	J
Number	1 u	3 u	6 u
Value	80	120	240
Total value	80 u	360 u	1440 u

(a)
Total mass of chilli powder
= 80 u + 360 u + 1440 u
= 1880 u

1880 u = 22560

1 u = 22560 ÷ 1880 = 12

Total number of containers of G and H used
= 1 u + 3 u
= 4 u
= 4 x 12
= 48 

(b)
Combined weight of all the chilli powder in containers H and containers J
= 360 u + 1440 u
= 1800 u

Difference between the combined weight of all the chilli powder in containers H and containers J as compared to the chilli powder in containers G
= 1800 u - 80 u
= 1720 u
= 1720 x 12
= 20640 g
= 20.64 kg 

Answer(s): (a) 48; (b) 20.64 kg
