In a shop, 60% of the number of vegetables sold were radishes and the rest were ginger. Each radish cost 25¢ and each ginger cost 10¢ less than the cost of each radish. Given that $218.40 was collected from the sale of the vegetables,
- How many radishes were sold?
- How much was collected from the sale of the ginger only?
(a)
|
Radishes |
Ginger |

$0.25 |
$0.15 |
Total value |
0.75 u |
0.3 u |
60% =
60100 =
35Cost of each ginger
= 0.25 - 0.10
= $0.15
Total cost of the vegetables
= 0.75 u + 0.3 u
= 1.05 u
1.05 u = 218.40
1 u = 218.40 ÷ 1.05 = 208
Number of radishes sold
= 3 u
= 3 x 208
= $624
(b)
Amount collected from the sale of ginger
= 0.3 u
= 0.3 x 208
= $62.40
Answer(s): (a) 624; (b) $62.40
