There were some pears, chikoos and passion fruits. The number of pears was five times the number of chikoos. The total number of pears and chikoos was half of the number of passion fruits. There were 180 fruits altogether. All the passion fruits were sold at 4 for $12. How much money was collected from the sale of the passion fruits?
Number of chikoos = 1 u
Number of pears = 5 u

Total number of chikoos and pears
= 1 u + 5 u
= 6 u

Number of passion fruits
= 2 x 6 u
= 12 u

Total number of fruits
= 1 u + 5 u + 12 u
= 18 u

18 u = 180

1 u = 180 ÷ 18 = 10

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

Number of sets of 4 passion fruits
= 120 ÷ 4
= 30

Amount collected from the sale of passion fruits
= 30 x 12
= $360

Answer(s): $360
