There were some pears, kiwis and passion fruits. The number of pears was four times the number of kiwis. The total number of pears and kiwis was one-quarter of the number of passion fruits. There were 150 fruits altogether. All the passion fruits were sold at 8 for $9. How much money was collected from the sale of the passion fruits?
Number of kiwis = 1 u
Number of pears = 4 u

Total number of kiwis and pears
= 1 u + 4 u
= 5 u

Number of passion fruits
= 4 x 5 u
= 20 u

Total number of fruits
= 1 u + 4 u + 20 u
= 25 u

25 u = 150

1 u = 150 ÷ 25 = 6

Number of passion fruits sold
= 20 u
= 20 x 6
= 120

Number of sets of 8 passion fruits
= 120 ÷ 8
= 15

Amount collected from the sale of passion fruits
= 15 x 9
= $135

Answer(s): $135
