Three types of curry powder, V, W and X come in containers of 100 g, 150 g and 300 g respectively. Containers of V, W and X are mixed together in the ratio 1 : 3 : 5 to obtain 24.6 kg of an assortment of curry powder.

1. How many containers of V and W are used altogether?
2. Find the difference between the combined weight of all the curry powder in containers W and containers X as compared to the curry powder in containers V. Express the weight in kilograms.

	V	W	X
Number	1 u	3 u	5 u
Value	100	150	300
Total value	100 u	450 u	1500 u

(a)
Total mass of curry powder
= 100 u + 450 u + 1500 u
= 2050 u

2050 u = 24600

1 u = 24600 ÷ 2050 = 12

Total number of containers of V and W used
= 1 u + 3 u
= 4 u
= 4 x 12
= 48 

(b)
Combined weight of all the curry powder in containers W and containers X
= 450 u + 1500 u
= 1950 u

Difference between the combined weight of all the curry powder in containers W and containers X as compared to the curry powder in containers V
= 1950 u - 100 u
= 1850 u
= 1850 x 12
= 22200 g
= 22.2 kg 

Answer(s): (a) 48; (b) 22.2 kg
