Three types of chilli powder, J, K and L come in containers of 60 g, 150 g and 210 g respectively. Containers of J, K and L are mixed together in the ratio 1 : 4 : 5 to obtain 10.26 kg of an assortment of chilli powder.

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

	J	K	L
Number	1 u	4 u	5 u
Value	60	150	210
Total value	60 u	600 u	1050 u

(a)
Total mass of chilli powder
= 60 u + 600 u + 1050 u
= 1710 u

1710 u = 10260

1 u = 10260 ÷ 1710 = 6

Total number of containers of J and K used
= 1 u + 4 u
= 5 u
= 5 x 6
= 30 

(b)
Combined weight of all the chilli powder in containers K and containers L
= 600 u + 1050 u
= 1650 u

Difference between the combined weight of all the chilli powder in containers K and containers L as compared to the chilli powder in containers J
= 1650 u - 60 u
= 1590 u
= 1590 x 6
= 9540 g
= 9.54 kg 

Answer(s): (a) 30; (b) 9.54 kg
