There were some pomegranates, pears and passion fruits. The number of pomegranates was three times the number of pears. The total number of pomegranates and pears was one-third of the number of passion fruits. There were 160 fruits altogether. All the passion fruits were sold at 8 for $12. How much money was collected from the sale of the passion fruits?
Number of pears = 1 u
Number of pomegranates = 3 u

Total number of pears and pomegranates
= 1 u + 3 u
= 4 u

Number of passion fruits
= 3 x 4 u
= 12 u

Total number of fruits
= 1 u + 3 u + 12 u
= 16 u

16 u = 160

1 u = 160 ÷ 16 = 10

Number of passion fruits sold
= 12 u
= 12 x 10
= 120

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

Amount collected from the sale of passion fruits
= 15 x 12
= $180

Answer(s): $180
