In a stall, 60% of the number of vegetables sold were radishes and the rest were ginger. Each radish cost 25¢ and each ginger cost 20¢ less than the cost of each radish. Given that $236.30 was collected from the sale of the vegetables,
- How many radishes were sold?
- How much was collected from the sale of the ginger only?

$0.05 |
Total value |
0.75 u |
0.1 u |
60% =
60100 =
35Cost of each ginger
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.1 u
= 0.85 u
0.85 u = 236.30
1 u = 236.30 ÷ 0.85 = 278
Number of radishes sold
= 3 u
= 3 x 278
= $834
(b)
Amount collected from the sale of ginger
= 0.1 u
= 0.1 x 278
= $27.80
Answer(s): (a) 834; (b) $27.80
