In a shop, 75% of the number of vegetables sold were ginger and the rest were turnips. Each ginger cost 25¢ and each turnip cost 20¢ less than the cost of each ginger. Given that $250.40 was collected from the sale of the vegetables,
- How many ginger were sold?
- How much was collected from the sale of the turnips only?
(a)
|
Ginger |
Turnips |

3 u |
1 u |
Value |
$0.25 |
$0.05 |
Total value |
0.75 u |
0.05 u |
75% =
75100 =
34Cost of each turnip
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 0.75 u + 0.05 u
= 0.8 u
0.8 u = 250.40
1 u = 250.40 ÷ 0.8 = 313
Number of ginger sold
= 3 u
= 3 x 313
= $939
(b)
Amount collected from the sale of turnips
= 0.05 u
= 0.05 x 313
= $15.65
Answer(s): (a) 939; (b) $15.65
