In a kiosk, 60% of the number of vegetables sold were ginger and the rest were garlics. Each ginger cost 25¢ and each garlic cost 10¢ less than the cost of each ginger. Given that $235.20 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the garlics only?
(a)
|
Ginger |
Garlics |
Number |
3 u |
2 u |
Value |
$0.25 |
$0.15 |
Total value |
0.75 u |
0.3 u |
60% =
60100 =
35Cost of each garlic
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.3 u
= 1.05 u
1.05 u = 235.20
1 u = 235.20 ÷ 1.05 = 224
Number of ginger sold
= 3 u
= 3 x 224
= $672
(b)
Amount collected from the sale of garlics
= 0.3 u
= 0.3 x 224
= $67.20
Answer(s): (a) 672; (b) $67.20
