Three types of pepper, G, H and J come in containers of 150 g, 200 g and 250 g respectively. Containers of G, H and J are mixed together in the ratio 1 : 2 : 3 to obtain 14.3 kg of an assortment of pepper.

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

	G	H	J
Number	1 u	2 u	3 u
Value	150	200	250
Total value	150 u	400 u	750 u

(a)
Total mass of pepper
= 150 u + 400 u + 750 u
= 1300 u

1300 u = 14300

1 u = 14300 ÷ 1300 = 11

Total number of containers of G and H used
= 1 u + 2 u
= 3 u
= 3 x 11
= 33 

(b)
Combined weight of all the pepper in containers H and containers J
= 400 u + 750 u
= 1150 u

Difference between the combined weight of all the pepper in containers H and containers J as compared to the pepper in containers G
= 1150 u - 150 u
= 1000 u
= 1000 x 11
= 11000 g
= 11 kg 

Answer(s): (a) 33; (b) 11 kg
