In a shop, 70% of the number of vegetables sold were yams and the rest were radishes. Each yam cost 25¢ and each radish cost 20¢ less than the cost of each yam. Given that $197.60 was collected from the sale of the vegetables,
- How many yams were sold?
- How much was collected from the sale of the radishes only?
(a)
|
Yams |
Radishes |
Number |
7 u |
3 u |
Value |

$0.05 |
Total value |
1.75 u |
0.15 u |
70% =
70100 =
710Cost of each radish
= 0.25 - 0.20
= $0.05
Total cost of the vegetables
= 1.75 u + 0.15 u
= 1.9 u
1.9 u = 197.60
1 u = 197.60 ÷ 1.9 = 104
Number of yams sold
= 7 u
= 7 x 104
= $728
(b)
Amount collected from the sale of radishes
= 0.15 u
= 0.15 x 104
= $15.60
Answer(s): (a) 728; (b) $15.60
